[0002] With the acceleration of urbanization, the safety and durability of building structures have become key issues in architectural design. Traditional structural strength analysis methods mainly rely on theoretical calculations and experimental tests. Although these methods can evaluate the performance of structures to a certain extent, they often ignore complex factors such as material layout and load distribution during the actual use of buildings, resulting in a large deviation between the analysis results and the actual situation.

[0003] In recent years, the rise of BIM technology has brought revolutionary changes to building design and construction. BIM technology integrates all relevant information of a building project, including geometric dimensions, material properties, construction details, etc., by building a three-dimensional digital model, providing a new means for structural strength analysis. However, a simple BIM model is still difficult to fully reflect the complex situation of a building in actual use, especially the impact of factors such as material layout, personnel flow, and equipment placement on structural strength.

[0004] Therefore, the present invention proposes a building structure strength simulation analysis method based on BIM model and big data analysis, aiming to achieve accurate assessment of building structure strength by integrating BIM technology and big data analysis technology, and provide a more reliable basis for building design and structural optimization.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0025] like Figure 1As shown, an embodiment of the present invention discloses a method for simulating and analyzing the strength of a building structure, the method comprising the following steps: Receiving structural design data of a target building and material data of each regional structure, constructing a BIM model of the target building based on the structural design data, and configuring each material data at a corresponding position in the BIM model to obtain a first BIM model; Acquire usage planning data of the target building, predict material layout conditions of various areas of the target building according to the usage planning data, and fuse the material layout conditions with the first BIM model to obtain a second BIM model; The structural strength analysis of the second BIM model is performed using a finite element analysis method to obtain and output structural strength analysis result data.

[0026] After receiving the structural design data of the target building and the material data of each regional structure, the present invention first constructs a basic BIM model of the target building based on the structural design data, and configures each material data at the corresponding position in the basic BIM model, that is, marks the design and use material conditions of each regional position in the BIM model, thereby obtaining a first BIM model. At the same time, the present invention further obtains the use planning data of the target building, predicts the material layout of each area of ​​the target building based on the use planning data, and the material layout is the material distribution inside the target building after it is completed and put into use. The material layout is integrated with the first BIM model to obtain a second BIM model. Finally, the existing finite element analysis method is used to perform structural strength analysis on the second BIM model, and the structural strength analysis result data is obtained and output. Then, the designer can optimize the original structural design data of the target building to a certain extent based on the obtained structural strength analysis result data.

[0027] In the above scheme of the present invention, the structural strength simulation analysis is not performed on the structural design data of the target building itself, but the material layout of the target building during use after it is completed and put into use is predicted at the same time, and then the structural strength analysis is performed on the structural design data based on the material layout, so as to obtain structural strength analysis result data with more reference value, which is conducive to designers making more reasonable structural designs.

[0028] Optionally, the structural design data includes geometric dimensions, structural form, and component size information of the building; and the material data includes material types and material strength parameters used in the structures of each region.

[0029] Material strength includes Young's modulus, Poisson's ratio, yield strength, etc.

[0030] Optionally, constructing a BIM model of the target building based on the structural design data, and configuring each of the material data at a corresponding position in the BIM model to obtain a first BIM model, comprising: Importing the geometric dimensions, structural form, and component size information of the building in the structural design data into BIM software, and using the BIM software to construct a three-dimensional model of the target building using parametric modeling technology, wherein the three-dimensional model contains the geometric information, structural component information, and material property information of the building, and the three-dimensional model is the BIM model; Through the property editing function of the BIM software, each material data is configured at a corresponding position in the BIM model to ensure that the physical properties of the BIM model are consistent with the actual material, and the first BIM model is obtained. The first BIM model includes the structural design data of the target building and the material data of each regional structure.

[0031] After completing the construction of the first BIM model, it needs to be exported into a format that can be recognized by other analysis software for further structural strength analysis.

[0032] Optionally, obtaining usage planning data of the target building, and predicting the material layout of each area of ​​the target building according to the usage planning data, includes: Acquiring use planning data of a target building, wherein the use planning data includes a functional layout of each area of ​​the target building; Crawling and obtaining building usage big data corresponding to each of the functional layouts, analyzing the building usage big data, and predicting building usage data, wherein the building usage data includes the type, quantity, and location of materials that may be placed in each area; The material weight distribution data of each area is obtained based on the building usage data analysis.

[0033] Before designing and constructing the target building, it is necessary to clarify the functional layout of each area inside it, such as office area, conference room, warehouse, etc., that is, use planning data. Then, crawl the building usage big data corresponding to each functional layout on the Internet. Building usage big data refers to the material layout in the area of ​​the functional layout in the existing building. Thus, the building usage data is predicted through big data integration and analysis technology. The building usage data includes the type, quantity and location of materials that may be placed in each area. Then, the material weight distribution data of each area is analyzed based on the obtained building usage data. For example, the material weight of each sub-area can be predicted based on the material type and quantity of each sub-area, thereby obtaining the material weight distribution data of the area.

[0034] Optionally, the crawling obtains building usage big data corresponding to each of the functional layouts, including: Performing novelty analysis on each of the functional layouts to obtain a corresponding novelty level, and determining a time span of a crawling period corresponding to each of the functional layouts according to the novelty level; wherein the crawling period has a starting point of the current time and an end point of the historical time, and the size of the time span is negatively correlated with the novelty level; Building usage big data corresponding to each of the functional layouts is obtained by crawling according to the crawling period corresponding to the time span.

[0035] The time span of the crawling period of the building usage big data crawled by the present invention is different from that of the functional layout. Specifically, the novelty level of each functional layout itself is first determined, and then the time span of the crawling period corresponding to each functional layout is determined according to the novelty level according to the negative correlation. Among them, the starting point of the crawling period is the current time and the end point is the historical time. In this way, it is possible to crawl only the "recent" building usage big data for the relatively novel functional layout, and crawl the "recent + long-term" building usage big data for the non-novel and mature functional layout. Such a setting can reduce the interference of irrelevant historical data to improve the confidence of the building usage data obtained through analysis.

[0036] Among them, crawling entrances for big data used in buildings include but are not limited to public databases, sensor networks, building management systems and the Internet.

[0037] Optionally, performing novelty analysis on each of the functional layouts to obtain a corresponding novelty level includes: A network-wide search is performed for the functional layout, and a corresponding novelty level is calculated based on the number of search results.

[0038] The novelty level of a functional layout in a target building can be determined by analyzing the amount of data related to the network content, that is, searching the entire network for the functional layout and calculating the corresponding novelty level based on the number of search results. Obviously, the more search results there are, the lower the novelty level is, and vice versa.
