Application of BIM technology in architectural structure design?

The design of building structure is related to its construction quality, production cycle of building products, wide influence range and large production scale. Therefore, the design of building structure will have a great influence on the final product quality of the building. As a design unit, in order to improve the quality of architectural design, bim technology can be used to improve its design level, ensure the safety and stability of architectural design, and meet the diversified requirements of current users. In this paper, the introduction of BIM technology in building structure design is deeply analyzed for the reference of relevant people.

1 Introduction

At present, BIM software products are influenced by BIM technology, and the related design ideas and applications are constantly improved and perfected, which realizes the information exchange and communication between different professions, which is very beneficial to the professional cooperation and scheduling in engineering construction. For building structure design, the application of BIM technology can effectively analyze the diverse needs of different users, carry out project site selection and model establishment, and help designers understand the rationality of the design scheme. The visual digital model of BIM technology can also help users to simulate and analyze the building structure, so that the construction unit can better understand the designer's intentions and ideas, and improve the overall quality and production efficiency of the structural design of building products.

Characteristics of 2 2 BIM technology

BIM refers to the building information model. With the development of digital technology, BIM technology has matured and improved. At present, BIM technology has been applied to the operation of various projects, which has promoted the construction of construction projects. BIM technology transforms engineering construction from a two-dimensional model into a three-dimensional model by establishing a three-dimensional model of computer simulation, and applies digital technology to establish an information base in line with the actual situation of construction projects. In the process of establishing information database, we can get collective information and professional information about the project, even including the state information of non-component objects, such as space and operation behavior, which is beneficial to architectural structure design.

3BIM technology in the concrete application of building structure design

3. 1 Used for building structure and site analysis.

The rationality of building structure design is not only reflected in the stability and safety of the building structure itself, but also closely related to the environment and geological conditions of the construction site. BIM system can be connected with GIS, simulate the construction site, establish the construction project model, comprehensively analyze the characteristics and conditions of the construction site, and select the best construction site to achieve the best adaptability of the building structure and site.

3.2 Performance analysis applied to building structures

The so-called architectural structure design is not only a simple arrangement of parts, but also to ensure the seismic resistance and firmness of the building structure to meet the requirements of building quality. In the traditional analysis work, the analysis of building structure function needs a lot of manpower and takes a long time to complete, and the analysis results will also appear errors. BIM technology has performance analysis software, and the analysis process can be realized only by importing the data information of BIM model into the software. If we find the shortcomings in the current architectural design, we will make changes immediately, which will effectively improve the quality of architectural structure design.

3.3 Synergy of building structure

In the BIM model, the data information of construction projects is constantly updated and increased. In order to ensure the design quality, it is necessary to make statistics and enjoy the data. In this process, we need to pay attention to the following two aspects: ① With the help of intermediate data files, we can meet the model design requirements of different design software in different places and provide them with necessary data information; (2) Set up a medium-sized database reasonably to ensure that there is no obstacle to data exchange between different majors. Such different professional design contents, such as plumbing, civil engineering, decoration, etc. , can be integrated and analyzed with the help of a unified platform to ensure the coordination of architectural structure design.

3.4 Applied to steel structure modeling

At present, steel structure has become an important structural form in long-span buildings, but many problems such as structural connection and reinforcement arrangement are often encountered in the modeling process, and different connection forms such as beam-to-column connection, beam-to-beam hinge and beam-to-beam rigid connection will also be involved in steel structure design. Therefore, in the design process, it is necessary to design and parameterize each connector according to the specific height of the beam. The advantages of BIM system in steel structure modeling are that parameters can be shared and the number and spacing of bolts can be controlled. As a designer, the design and manufacture of new connectors can only be realized by adjusting parameters. In the design of steel bars and connectors, designers only need to draw basic details, and in the construction of steel structures, workers only need to accurately locate steel bars and connectors according to the design of corresponding parts.

Application Difficulties of 4BIM in Structural Design

When applying BIM technology, there will also be some problems, which will affect the application effect of BIM technology more or less. Details are as follows:

① There is no standard system as a reference, because the application of BIM technology is still in the exploratory stage, and its application has not been standardized. Because the most important thing in the application of BIM technology is the exchange of information, the coordination between BIM standards and software is very important;

(2) Legal responsibility, which is embodied in the legality and effectiveness of BIM technology in the use process. The transfer of parameters will also involve property rights and responsibilities, and the content of modeling is similar to that of traditional technology;

(3) Application and delivery. In different stages of the design process, the depth and content of BIM technology design will be different, and the design standards will be different;

(4) The technical defects of BIM, because the current BIM technology is still in the promotion stage. The problems existing in the promotion are: adopting foreign software, low localization level, strict requirements for staff's working ability, imperfect connection of various modules in the software, low degree of data sharing and data transmission;

⑤ The use cost is relatively high, and a lot of money needs to be invested in technicians and equipment to ensure the advanced nature of equipment and software;

⑥BIM technology archiving, which requires high hardware configuration, needs to improve its configuration level, which will increase costs. Therefore, it is imperative to solve the problem of BIM technology document storage.

Processing Method of 5BIM in Structural Design

5. 1 Create a complete project template

Project template is the basis of design work. The main contents of project template include limited standardized families, lines, fonts, symbols and expressions. In BIM technology, it is necessary to form a good quality model, which can reduce workload, avoid duplication of work content and improve design efficiency.

5.2 Design structural members that meet the requirements

The types of components involved in structural design include foundation, column, wall, beam, floor and stairs. These components can be divided into three types according to the construction type, namely prefabricated components, cast-in-place components and steel structure workpieces. At this time, these structural members can be designed with the main design form of the building as the reference standard. At present, cast-in-place components are common structural types in construction projects. When designers choose their design schemes, they usually choose according to the design requirements and construction objectives of construction projects to avoid contradictions among various factors in structural components.

5.3 Plane representation in reinforced concrete structures

In the process of drawing reinforced concrete construction drawings, the plane method is generally used to express its contents, and the drawings are marked with obvious signs, so that the construction personnel can intuitively identify and understand the relevant contents of the construction drawings through these signs, and can also be converted into sample drawings. The application of BIM technology can make the content of plane expression more diverse and the expression methods more diverse. The establishment of BIM model can also easily obtain key data and core information, which can well meet the requirements of construction time and lofting.

5.4BIM model analysis

Revit and PKPM are widely used in BIM. Revit focuses on the establishment of BIM model, but the use of PKPM ensures the balance of structural stress and can be closely related to relevant codes and standards. However, there are still some problems in the process of data exchange between the two softwares. For example, data exchange needs the help of third-party software, and only in this way can data be converted into a common format.

6 concluding remarks

To sum up, BIM technology develops rapidly and matures day by day, which has a great influence on structural design. At present, in the process of applying BIM technology to structural design, there will be some problems, such as unreasonable design caused by human factors. Therefore, it is necessary to strengthen and improve the professional quality of staff, improve their comprehensive ability, master the operation principle and application of BIM technology skillfully, and efficiently complete the design work of building projects in the technology of ensuring the design quality of building structures, thus ensuring the scientificity, safety and stability of building structures.
