[0002] With the rapid development of digital technology, the application scenarios of web applications continue to expand and extend in depth. In many fields such as architecture and engineering, the demand for displaying and analyzing complex models on the web is extremely urgent, so web-based mesh model construction technology has become key. Building Information Modeling (BIM) can integrate various types of information throughout the life cycle of a building, and Finite Element Models (FEM) are widely used in the engineering field to simulate and analyze structural mechanical behavior. Currently, converting BIM and FEM into mesh models that can be used on the web through specific conversion methods has become an academic hotspot.

[0003] Current research often focuses on single-model conversion, such as converting only BIM model geometry and some building attributes, or solely focusing on FEM mechanical performance characterization. An ideal web-based mesh model should not only accurately represent inherent structural characteristics such as load effects, stiffness distribution, and structural dynamics, but also fully reflect the complex mechanical behavior during construction, as well as aspects such as structural safety and comfort, and structural degradation performance. Therefore, in-depth research on the conversion interface between different models and web-based mesh models is essential. Summary of the Invention

[0054] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0055] Figure 1 This is a flowchart provided by an embodiment of a method for generating a web page model for structural information of the present invention. Figure 1 , this embodiment may include the following steps:

[0056] S1. Extracting BIM model geometric information and generating a web-based mesh model that can represent structural geometric information based on the BIM model geometric information;

[0057] S2. By extracting structural information from the Abaqus local structural model and using mesh expansion and integration, a local web-based model that can represent the local structural mechanical information is generated;

[0058] S3. By extracting the structural component composition information, geometric coordinate information and cross-sectional form information from the Opensees overall structural model, coordinate transformation is used to generate an overall web-based model that can represent the overall structural mechanical information;

[0059] S4. Build a web-side visualization environment, import the web-side grid model, the local web-side model and the overall web-side model description, construct the model interaction function module, and realize the visualization of the model.

[0060] It is understandable that although Figure 1 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily performed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction for the execution of these steps, and these steps can be performed in other orders.

[0061] Preferably, step S1 includes:

[0062] Extract Revit model information through GltfContextExporter function;

[0063] Convert entities in Revit model information into Brep format, and store the converted Brep components in the form of triangular facets;

[0064] The model information is lightweight by deleting redundant vertices in Brep format components;

[0065] The Revit model coordinate system is converted to the web coordinate system through the Translation function, Zoom function, and Rotate function, thereby generating a web grid model that can represent the structural geometric information.

[0066] Preferably, the model information is lightweighted by deleting redundant vertices in the Brep format component, including:

[0067] Determine a target node and two nodes adjacent to the target node; wherein the two nodes adjacent to the target node are: a first adjacent node and a second adjacent node;

[0068] Determine a first vector of an edge formed by a target node and a first adjacent node;

[0069] Determine a second vector of an edge formed by the target node and the second adjacent node;

[0070] determining an angle between the first vector and the second vector;

[0071] If the angle is greater than the preset angle, the target node is a redundant vertex.

[0072] It can be understood that step S1 includes extracting Revit model information, lightweighting the model information, and converting the coordinates of the model information.

[0073] Extracting Revit model information involves writing a Revit model information storage module, GltfContextExporter, in C# based on Revit secondary development. This module primarily involves determining the Revit model's base coordinate system, traversing model instances (structural components), obtaining member information, and obtaining model geometry information, ultimately transforming the Revit model into a web-based mesh model file.

[0074] The GltfContextExporter function contains a series of custom sub-functions, such as OnViewBegin, OnElementBegin, OnMaterial, OnPolymesh, OnElementEnd, and OnViewEnd. These functions have clear divisions of labor: OnViewBegin initiates the information collection process, OnElementBegin prepares for member processing, OnMaterial handles material information processing, OnPolymesh parses polygon mesh data, OnElementEnd completes information verification, and OnViewEnd aggregates and integrates the information.

[0075] The specific method of lightweighting model information is to convert the entities in Revit into Brep format. The components converted into Brep format are stored in the form of triangular facets. The components in Brep format contain redundant vertices. The lightweighting of model information is achieved by deleting redundant vertices.

[0076] Redundant vertices include two types: overlapping vertices and irrelevant detail vertices, such as Figure 2 As shown, point E is a coincident node, and point F is an irrelevant detail vertex. Redundant vertices are deleted by traversing and comparing node information. Duplicate nodes and nodes with the same coordinates are redundant nodes. Redundant nodes are structural boundaries and nodes with large angles with adjacent nodes. By judging the vector of the edge formed between the vertex and the two surrounding points, The angle θ between the two vectors is:

[0077]

[0078] For θ greater than 175°, the vertices are considered redundant.

[0079] The Draco algorithm is used to further simplify the model.

[0080] Model information coordinate conversion specifically involves converting the model from the Revit coordinate system to the web page coordinate system. Key operations include translation, scaling, and rotation. Function modules Translation, Zoom, and Rotate are written to implement these operations.

[0081] Preferably, step S2 includes:

[0082] Extract the information of Inp file in Abaqus local structure model through modelParse module;

[0083] Based on the extracted information, beam elements and shell elements are determined in the mesh elements of the Abaqus local structural model;

[0084] Based on the cross-sectional information of beam and shell elements, the beam and shell elements are converted into cylindrical rectangular structures with 8 nodes, completing the mesh expansion of the Abaqus local structural model.

[0085] Based on the extracted information and the expanded mesh elements of the Abaqus local structural model, a local web-based model that can represent the local structural mechanics information is generated.

[0086] It is understandable that step S2 includes local structure information extraction and coordinate expansion

[0087] The local structure information extraction is specifically as follows:

[0088] Based on the Inp file in Abaqus, the information contained in the node data block, element data block, and local structure data block is extracted. The Python-based information acquisition module modelParse contains four core functions: parse_node_coordinates parses node numbers and coordinates from the Inp file, storing them in the dictionary format {node number:node coordinate}; parse_line_elements parses and stores beam element information in the dictionary format {beam element number:[node 1 number, node 2 number]}; parse_shell_elements extracts information from the Inp file and stores it in the format {shell element number:[node 1 coordinate, node 2 coordinate, node 3 coordinate, node 4 coordinate]}. The parse_nset function parses and stores set information in the structure in the array format [node 1 number, node 2 number, ...].

[0089] The modelParse module can be used to extract different Abaqus grid information.

[0090] The coordinate expansion is as follows:

[0091] The mesh elements in the Abaqus model mainly include hexahedral elements, tetrahedral elements, beam elements, and shell elements. This method will render beam elements, shell elements, hexahedral elements, and tetrahedral elements into three-dimensional web page solid graphics. Among them, hexahedral elements and tetrahedral elements have been rendered as three-dimensional solid graphics, so there is no need to perform further unit expansion rendering operations on their plates, such as Figure 3 As shown in the figure, the beam element itself only contains information about two nodes. During the element expansion process, an array function needs to be written to convert it into a columnar rectangular structure with 8 nodes based on the cross-section information, such as Figure 4 As shown in the figure, the shell element itself only contains information about four nodes. During the element expansion process, you need to write the array1 function to convert it into a cylindrical rectangular structure with 8 nodes based on the cross-section information, such as Figure 5 shown.

[0092] Preferably, step S3 includes:

[0093] The model_Opensees_parse module is used to parse the Tcl file of the Opensees overall structural model to extract the structural component composition information, geometric coordinate information and cross-sectional form information;

[0094] The geometric coordinate information is converted through the geomTransfer function to convert the local coordinate system of the Opensees overall structure model into the global coordinate system;

[0095] Section information includes dispBeamColumn and Fiber_Section.

[0096] According to the cross-sectional information of the dispBeamColumn form, the dispBeamColumn form is converted into a columnar rectangular structure with 8 nodes;

[0097] According to the cross-sectional information in the Fiber_Section format, each fiber cross-sectional area in the Fiber_Section format is expanded to eight-node information;

[0098] An overall web-based model that can represent the overall structural mechanics information is generated based on the structural component composition information, the converted geometric coordinate information and the expanded cross-sectional form information.

[0099] It can be understood that step S3 includes overall structural information extraction, node coordinate conversion and cross-section information conversion.

[0100] The overall structural information extraction is specifically as follows:

[0101] The model_Opensees_parse module, written in Python, parses Opensees Tcl files. It contains two core functions: parse_node_coordinates parses node numbers and coordinates from Tcl files and stores them in a dictionary format of {node number:node coordinate}. This facilitates the rapid extraction of large numbers of node coordinates from complex finite element models for subsequent analysis. The parse_elements function parses and stores component element information in a dictionary format of {component element number:[node 1 number, node 2 number]}, facilitating the understanding of component element connectivity.

[0102] The node coordinate transformation is as follows:

[0103] The coordinates of the Opensees model components are in the local coordinate system, and the model nodes on the web page are in the global coordinate system. The geomTransfer function is used to implement the coordinate conversion of the model nodes.

[0104] The specific conversion of cross-section information is as follows:

[0105] The Opensees model contains two cross-section types: dispBeamColumn and Fiber_Section. The dispBeamColumn type only contains information about two nodes. During element expansion, you need to write an array function to convert it into a cylindrical rectangular structure with eight nodes based on the cross-section information. The Fiber_Section type contains multiple fiber cross-sections, each of which contains only two nodes. This type needs to be expanded to eight nodes.

[0106] Preferably, step S4 includes:

[0107] Build a web-based visualization environment based on the Three.js framework;

[0108] Import the web page grid model directly into the web page visualization environment through Gltfloader to realize the visualization of the web page grid model;

[0109] Use the Indicies function to write component index numbers for the local web model and the overall web model respectively, and use the SetAttribute function and material function to import the local web model and the overall web model into the web visualization environment and assign material attributes to achieve visualization of the local web model and the overall web model;

[0110] Introducing the Controls function into the Three.js framework to implement model scaling, movement, and roaming functions;

[0111] By monitoring the changes of the Camera component, the perspective change is achieved, the Raycaster function is introduced to realize component selection, the Outlinepass function is used to realize component click highlighting, and the table function is written to realize the table display of component information when the component is clicked and highlighted, so as to realize the interactive visualization of the model.

[0112] It can be understood that step S4 includes setting up a web-side visualization environment, loading a model for the web-side visualization environment, and visualizing interactive models on the web-side.

[0113] The specific construction of the web-side visualization environment is as follows:

[0114] Build a web-based visualization environment based on the Three.js framework. The web-based visualization environment consists of multiple modules, including the Camera module, Light module, Loader module, and Render module. Import the corresponding modules into the front-end web framework to build the visualization environment.

[0115] The model loading for the web-based visualization environment is as follows:

[0116] For the web-based mesh model generated from the Revit model in S1, Gltfloader can be used to directly import it into the visualization environment, enabling geometric visualization of the web-based model. For the web-based models generated from the finite element model in S2 and S3, the Indicies function is used to set the component index number. Then, the SetAttribute and material functions are used to import it into the visualization environment and assign material properties to achieve visualization of the web-based model.

[0117] The interactive visualization of the web-side model is as follows:

[0118] In the Three.js framework, the Controls function is introduced to implement model scaling, movement, and roaming functions. The perspective change is achieved by monitoring the changes of the Camera component. The Raycaster function is introduced to implement component selection. The Outlinepass function is used to achieve component click highlighting. Figure 6 As shown; write the table function to realize the display of component information in the table when the component is clicked and highlighted, as shown Figure 7 shown.
