Description

TECHNICAL FIELD

[0001] The present application relates to the field of three-dimensional modeling, in particular to a modeling method, device and equipment for a steel reinforced concrete model. BACKGROUND

[0002] The steel reinforced concrete composite structure has been widely used in modern buildings, especially in high-rise buildings, large-span frames and complex shear wall structures, due to its excellent bearing capacity and seismic performance. Among them, the single-pier H-shaped and cross-shaped solid-web steel reinforced concrete joint as the key connecting part, its mechanical properties directly determine the safety and reliability of the overall structure. Therefore, during the structural design stage, it is necessary to use finite element analysis and other means to accurately simulate the mechanical properties of such joints, and the simulation analysis is based on the rapid and accurate establishment of the three-dimensional geometric model of the joint.

[0003] At present, the mainstream method for constructing the three-dimensional geometric model of such joints in the industry is for the designer to manually model by using general CAD software or the pre-processing module of finite element software. This process usually includes the following steps: first, positioning the shaft in the three-dimensional space, then drawing the reinforcement mesh (including longitudinal reinforcement and stirrup) by manually copying, offsetting and other operations; then, drawing the steel section profile according to the design size, generating the steel solid by stretching, rotating and other commands, and combining and trimming it with the concrete part by Boolean operation and other operations. However, this modeling method which highly depends on manual operation has the following significant defects: first, the modeling process is tedious and the repetitive workload is large, which leads to extremely low efficiency and makes it difficult to meet the modern rapid iteration design requirements; second, manual operation is prone to errors, for example, the geometric fit between different components (steel, reinforcement, concrete) is insufficient, which leads to the fact that the components that should be connected are not effectively coupled in the subsequent finite element analysis, thereby seriously affecting the accuracy of the calculation results; third, once the model is built, if any design parameter needs to be adjusted, the model often needs to be reconstructed from scratch, which lacks flexibility and makes the design optimization process costly and time-consuming.

[0004] Therefore, how to realize the rapid, accurate and parameterized three-dimensional geometric modeling of the H-shaped and cross-shaped solid-web steel reinforced concrete joint, so as to significantly improve the design efficiency and analysis reliability, has become a core problem to be solved in the field of building structure design and analysis software technology.

[0030] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0031] In view of the low efficiency, easy errors, insufficient fit, and inability to modify the size of the manually drawn H-shaped and cross-shaped solid-web steel reinforced concrete node three-dimensional model, the present application provides a grasshopper-based parameterized geometric modeling method for H-shaped and cross-shaped solid-web steel reinforced concrete nodes. Through this method, after programming, only the axis of the connecting rod and the size of the related components need to be input, and the H-shaped and cross-shaped solid-web steel reinforced concrete node three-dimensional model can be quickly generated.

[0032] The application is described in detail below Figures 1-11 The embodiments of the application are described in detail.

[0033] Figure 1 A flowchart of a modeling method of a steel reinforced concrete model provided by the application is shown in FIG. 1, which comprises the following steps: Figure 1 S110, obtaining axis geometric information of a connecting rod, steel section size, concrete member size and steel bar arrangement parameters. S110, obtaining axis geometric information of a connecting rod, steel section size, concrete member size and steel bar arrangement parameters.

[0034] According to the modeling method of the steel reinforced concrete model provided by the application, the form of the steel section includes an I-shaped section and a cross-shaped section; the I-shaped section size includes a flange width, a flange thickness, a web height and a web thickness of the H-shaped steel; and the cross-shaped section size includes a flange width, a flange thickness, a web height and a web thickness of the cross-shaped section.

[0035] According to the modeling method of the steel reinforced concrete model provided by the application, the steel bar arrangement parameters include a diameter, a number, an arrangement radius and a protective layer thickness of input longitudinal bars, and a diameter, a spacing, an encryption area range and a protective layer thickness of input stirrups.

[0036] Specifically, taking an I-shaped steel reinforced concrete beam-column joint as an example. First, the user inputs the central axis of the beam and column rod in the Grasshopper platform. Then, the I-shaped steel section parameters are defined: the flange width is 300 mm, the flange thickness is 20 mm, the web height is 500 mm and the web thickness is 15 mm. The concrete member size parameters include the beam-column section width, height and protective layer thickness. In the steel bar arrangement parameters, the longitudinal bars are HRB400 steel bars with a diameter of 25 mm, a total of 8, and are evenly distributed in the member width range; the stirrups are HPB300 steel bars with a diameter of 10 mm, and the encryption interval is 100 mm. After the input is completed, the parameterized algorithm of the Grasshopper automatically generates the I-shaped steel entity through "section along path stretching" according to the axis positioning and section parameters, generates the concrete outer layer through "offset surface", and generates the longitudinal bar and stirrup network through "layout along arrangement line". Finally, the model is ensured to be seamlessly fitted through Boolean operation, and supports real-time updating of the entire model after the user adjusts any parameter.

[0037] This embodiment significantly improves the efficiency and accuracy of I-shaped joint modeling through parameterized input and automatic generation, avoids geometric mispositioning problems in manual modeling, and greatly facilitates design optimization and scheme comparison through parameter-driven modification.

[0038] For the cross-section node, the user first inputs the axis geometric information of the intersecting bars. The cross-shaped steel section parameters are defined as follows: the flange width is 280 mm, the flange thickness is 18 mm, the web height is 450 mm, and the web thickness is 12 mm. The concrete size parameters include the node core size and the extension length in each direction. In the steel bar parameters, the longitudinal bar diameter is 22 mm, a total of 12 bars, and the arrangement radius is 180 mm; the stirrup diameter is 12 mm, and the spacing is 100 mm.

[0039] S120, generating a three-dimensional model according to the axis geometric information, the steel section size, the concrete member size and the steel bar arrangement parameters. The three-dimensional model includes a three-dimensional solid steel, a three-dimensional solid concrete and a steel bar line in a three-dimensional space.

[0040] According to the steel-concrete model modeling method provided by the application, a three-dimensional model is generated according to the axis geometric information, the steel section size, the concrete member size and the steel bar arrangement parameters, and specifically includes: determining the spatial orientation and positioning of the steel according to the axis geometric information; generating a three-dimensional steel model according to the steel section size based on the spatial orientation and positioning; generating a concrete three-dimensional model wrapping the steel according to the concrete member size based on the three-dimensional steel model; and generating a three-dimensional steel bar model according to the steel bar arrangement parameters based on the three-dimensional concrete model.

[0041] Specifically, the Grasshopper platform automatically determines the spatial orientation and positioning of the steel according to the axis geometric information, generates a three-dimensional I-shaped steel model through the “section along path stretching” algorithm; then generates a three-dimensional concrete outer layer model through the “offset surface” operation based on the steel model; finally, generates a three-dimensional entity network of longitudinal bars and stirrups based on the geometric boundary of the concrete model according to the steel bar parameters using the “layout along arrangement line” algorithm, and ensures that the steel bars are located in the concrete protective layer. The whole process is driven by parameters, and the model can be updated in real time.

[0042] The three-dimensional model is automatically generated through the parameterization process, which significantly improves the modeling efficiency, ensures the geometric fit degree between the steel, concrete and steel bars, avoids the common mispositioning and uncoupling problems in manual modeling, and provides a reliable foundation for subsequent accurate finite element analysis.

[0043] According to the steel-concrete model modeling method provided by the application, when the steel is a cross-section, generating a three-dimensional steel model includes: generating a first I-shaped steel entity; generating a second I-shaped steel entity orthogonal to the first I-shaped steel entity; and performing a Boolean set operation on the first I-shaped steel entity and the second I-shaped steel entity to obtain a three-dimensional cross-shaped steel model.

[0044] Specifically, Grasshopper first generates an orthogonal I-shaped steel entity according to the axis, and then fuses it into a cross-shaped steel through a Boolean union operation. The concrete part is generated through "stretching the outer contour of the section", and the reinforcement is automatically arranged according to the geometric characteristics of the node area. After the model is generated, the user can check the collision between the stirrup and the steel, and quickly update by adjusting the parameters.

[0045] The embodiment realizes the rapid construction of a complex cross-shaped node, ensures the geometric fitting degree of the steel, concrete and reinforcement through automatic Boolean operation and collision avoidance, improves the model reliability, and provides an accurate basis for finite element analysis.

[0046] According to the steel reinforced concrete modeling method provided by the application, after generating a three-dimensional model, the three-dimensional model is updated according to modified axis geometric information, steel section size, concrete component size and reinforcement arrangement parameters.

[0047] After the model is generated in any embodiment, if the design changes need to adjust the parameters, the user only needs to modify the corresponding input value. The Grasshopper platform will automatically re-execute the entire process: re-determine the steel positioning, update the steel three-dimensional entity, adjust the concrete outer layer size, and re-generate the reinforcement arrangement. All steps are driven by algorithms, without manual intervention, ensuring the consistency of the internal logic of the model and the overall fitting degree after updating.

[0048] The embodiment highlights the dynamic response capability and high flexibility of the method, greatly facilitates design iteration and scheme optimization, significantly shortens the model modification time caused by design changes, and avoids errors that may be introduced by manual updating.

[0049] As Figure 2 shown is a detailed process diagram of generating a three-dimensional model of a steel reinforced concrete node and a connecting rod based on a parameterized method. The user inputs the rod size, inputs the rod axis, and inputs the size of the concrete and steel node. These parameters provide basic data for subsequent geometry generation. According to the rod axis, the end points are obtained. Next, the process is divided into two main branches, which process the generation of rods and nodes respectively.

[0050] 1. Rod generation branch: first, generate a reference plane perpendicular to the rod axis. On the reference plane, draw the cross-sectional shape of the rod according to the input rod size parameter. Finally, stretch (extend) this section along the direction of the axis to generate a complete rod three-dimensional model.

[0051] 2. Node generation branch: analyze the bar axis to obtain its direction vector and end point position to determine the position and orientation of the node. According to the input concrete, steel section node size, generate various sections parallel to the bar axis, including concrete profile, steel section and key steel stiffening rib section.

[0052] Stretch each type of section generated in the previous step respectively. The concrete section stretching forms a solid cuboid, while the steel and stiffening rib section stretching forms the corresponding three-dimensional entity.

[0053] After the three-dimensional entities of the bar and the node are generated, two Boolean operations are performed to ensure the geometric relationship between them is perfect. First, "subtract" the part overlapping with the node entity from the bar entity, so as to form an interface on the bar matching the shape of the node. Then, perform "intersection" operation on the bar and the node, and finally obtain the three-dimensional model of the bar and the node seamlessly connected and perfectly matched with each other.

[0054] Figure 3 The bar axis generated according to the parameters of the application is shown in the figure. Figure 4 The node generation diagram is shown in the figure.

[0055] As Figure 5 The parameterized program logic diagram for generating a three-dimensional entity of concrete provided by the application is shown in the figure, Figure 6 The parameterized program logic diagram for generating a three-dimensional entity of steel mesh provided by the application is shown in the figure, Figure 7 The parameterized program logic diagram for generating a three-dimensional entity of steel provided by the application is shown in the figure. The process of generating a three-dimensional model is realized by a logical program flow in a parameterized modeling platform. The logical program flow usually includes a parameter input module, a vector conversion module, a section generation module and a Boolean operation module.

[0056] The parameter input module is used to receive the axis geometric information, steel section size, concrete member size and steel bar arrangement parameters input by the user.

[0057] The vector conversion module is used to calculate the space vector according to the axis geometric information, and determine the orientation, positioning and normal plane of the member in the three-dimensional space.

[0058] The section generation module is used to generate a steel section, a concrete section profile or a steel bar arrangement point on the normal plane according to the corresponding section size parameters.

[0059] The Boolean operation module is used to perform set union, set difference and other Boolean operations on the basic three-dimensional entity generated by section stretching, lofting and other operations, so as to form a complex geometric shape or ensure the geometric fitting relationship between the members.

[0060] As Figure 8As shown in the integrated program for generating the steel bar mesh, the user can input specific parameter values through the interface. For example, "width" defines the concrete section size (600mm x 900mm), the "cover" thickness is 30mm, the "number of longitudinal bars in the width direction" is 7, the "number of longitudinal bars in the height direction" is 6, the "spacing of stirrups" is 100mm, and the "number of stirrups" is 41. The program automatically completes the arrangement of longitudinal bars and stirrups and generates a three-dimensional entity based on these parameters.

[0061] As shown in the integrated program for generating the steel bar mesh, the user can input specific parameter values through the interface. For example, "width" defines the concrete section size (600mm x 900mm), the "cover" thickness is 30mm, the "number of longitudinal bars in the width direction" is 7, the "number of longitudinal bars in the height direction" is 6, the "spacing of stirrups" is 100mm, and the "number of stirrups" is 41. The program automatically completes the arrangement of longitudinal bars and stirrups and generates a three-dimensional entity based on these parameters. Figure 9 As shown in the integrated program for generating the steel bar mesh, the user can input specific parameter values through the interface. For example, "width" defines the concrete section size (600mm x 900mm), the "cover" thickness is 30mm, the "number of longitudinal bars in the width direction" is 7, the "number of longitudinal bars in the height direction" is 6, the "spacing of stirrups" is 100mm, and the "number of stirrups" is 41. The program automatically completes the arrangement of longitudinal bars and stirrups and generates a three-dimensional entity based on these parameters.

[0062] Figure 10 As shown in the integrated program for generating the steel bar mesh, the user can input specific parameter values through the interface. For example, "width" defines the concrete section size (600mm x 900mm), the "cover" thickness is 30mm, the "number of longitudinal bars in the width direction" is 7, the "number of longitudinal bars in the height direction" is 6, the "spacing of stirrups" is 100mm, and the "number of stirrups" is 41. The program automatically completes the arrangement of longitudinal bars and stirrups and generates a three-dimensional entity based on these parameters.

[0063] By specifically disclosing the logical program flow composed of parameter input, vector conversion, section generation, and Boolean operation modules, and combining specific parameter examples of the integrated program interface, the present application not only realizes the automation of the modeling process, but also ensures the geometric accuracy of the model from the mechanism. It puts the 'parameter-driven' concept into practice, through the explicit parameter-model mapping relationship, making the design modification intuitive and efficient, greatly improving the speed and quality of design iteration. At the same time, this standardized process lays the foundation for the popularization and application of technology, and is conducive to the standardization and intelligentization of modeling in engineering practice.

[0064] The parameterized modeling method of the present application overcomes the shortcomings of low efficiency, error-prone, insufficient fit, and inability to modify the size when manually drawing the three-dimensional model of the H-shaped and cross-shaped solid-web steel reinforced concrete joint, greatly improving the drawing efficiency and accuracy. The generated three-dimensional model not only serves for subsequent analysis, but also can be directly used as a tool to verify the rationality of the design parameters. Designers can observe the generated model from multiple angles, intuitively check the spatial relationship, collision situation, and geometric fit between the steel, concrete, and steel bars, and quickly verify or adjust the design input parameters.

The program automatically completes the arrangement of longitudinal bars and stirrups and generates a three-dimensional entity based on these parameters.
