I. Introduction.
With the development of science and technology and the continuous improvement of people's aesthetics, membrane structure, as a new type of architectural form, gradually occupies a place in the field of architecture. As an application form of membrane structure, the grandstand membrane structure has been widely used in stadiums, exhibition centers, public facilities and other fields. In this paper, the main steps of the analysis of the structure of the grandstand membrane will be elaborated in detail, so as to help readers better understand and master the analysis methods of the structure of the grandstand membrane.
2. Overview of the membrane structure of the stands.
The grandstand membrane structure is a form of spatial structure, which is mainly composed of three parts: membrane surface, support system and anchoring system. It has the characteristics of light weight, large span, short construction period and diverse shapes, which can effectively meet people's needs for architectural space. In the process of analyzing the membrane structure of the stand, it is necessary to consider the shape and size of the membrane surface, the layout and form of the support system, the type and position of the anchoring system, and other factors to ensure the stability and safety of the structure.
3. The main steps of the analysis of the structure of the grandstand membrane.
1.Determine the design goals.
First of all, it is necessary to clarify the design objectives of the grandstand membrane structure, including meeting the requirements of building function, structural safety and reliability, construction convenience and economic reasonableness. In the process of determining the design objectives, it is necessary to conduct in-depth analysis and research on the architectural scheme to understand the use function and space requirements of the building, so as to provide a basis for subsequent structural design.
2.Load analysis.
Load analysis is one of the important steps in the analysis of grandstand membrane structures, which requires the classification and combination of various loads to determine the magnitude and direction of the loads. In the load analysis, factors such as wind load, snow load, and self-weight load need to be considered, as well as dynamic loads such as personnel activities and equipment operation. Through the analysis of the load, the size and shape of the membrane surface and the support system can be determined to ensure the bearing capacity of the structure.
3.Membrane surface analysis.
Membrane surface analysis is the core step of grandstand membrane structure analysis, including shape analysis, stiffness analysis and strength analysis. The shape analysis mainly considers the geometry and size of the membrane surface to determine the layout and form of the support systemThe stiffness analysis mainly considers the deformation of the membrane surface under various loads to ensure the safety and stability of the structureThe strength analysis mainly considers the material properties and stress distribution of the membrane surface to determine the bearing capacity of the membrane surface. In the membrane surface analysis, numerical simulation methods and experimental methods need to be used for verification and verification.
4.Analysis of the support system.
The support system is an important part of the grandstand membrane structure, which needs to bear the load transmitted by the membrane surface and transfer it to the base structure. In the analysis of the support system, it is necessary to consider the type, layout form, material properties and connection mode of the support system to ensure the bearing capacity and stability of the support system. At the same time, it is also necessary to conduct detailed analysis and research on the connection between the support system and the infrastructure structure to ensure the integrity and stability of the structure.
5.Anchorage system analysis.
The anchoring system is another important component of the grandstand membrane structure, which is mainly used to fix the membrane surface on the base structure. In the analysis of the anchoring system, it is necessary to consider the type, layout form, material properties and connection mode of the anchoring system to ensure the bearing capacity and stability of the anchoring system. At the same time, it is also necessary to conduct detailed analysis and research on the connection between the anchoring system and the basic structure to ensure the integrity and stability of the structure.
6.Overall stability analysis.
The overall stability is one of the important indicators for the structural analysis of the grandstand membrane, which needs to be verified and verified by numerical simulation and experimental methods for the whole structure. In the overall stability analysis, it is necessary to consider the influence of various factors on the stability of the structure, such as external loads such as wind loads, snow loads, and self-weight loads, as well as internal factors such as the material properties and geometry of the structure itself. Through the analysis of the overall stability, the overall load-bearing capacity and safety of the structure can be determined.
7.Detailed construction analysis.
Detailed structure is one of the important aspects of the analysis of the structure of the grandstand membrane, which requires detailed analysis and research on the key parts and details in the structure. In the detailed structure analysis, it is necessary to consider the design of the connection part, the selection of materials, the processing technology and other factors to ensure the convenient and economical construction of the structure. At the same time, it is also necessary to verify and verify the experimental methods of the detailed structure to ensure the reliability and safety of the structure.
IV. Conclusions. As a new type of architectural form, the grandstand membrane structure has been widely used in the field of architecture. In this paper, the main steps of the membrane structure analysis of the grandstand are described in detail, including the determination of the design objectives, load analysis, membrane surface analysis, support system analysis, anchoring system analysis, overall stability analysis and detailed structure analysis. Through the in-depth understanding and mastery of these steps, the analysis level and design quality of the grandstand membrane structure can be effectively improved, and contribute to the development of the construction field.
