The Analysis Of Constructional Simulation Of The Large-span Spatial Steel Structure

With the development of science and technology in recent years, the long-span spatial structure becomes one of the fastest-growing structures in China. As the complex form of the large-span steel structure and relatively long construction period, the influence of construction process on the structure of the force and deformation is relatively large, misconduct may cause more serious consequences. So it is necessary for the long-span spatial structure to conduct the simulation analysis of construction course and the study on mechanical properties, which provide scientific basis for the construction of such structures.The main contents of this paper are as follows:1. The installation method analysis of the long-span space steel structure. Through the introduction of the construction method of the large span steel structure, this paper explains essential differences in construction techniques, construction sequence and construction methods for the different structures, which provides the theoretical basis to adopt the correct construction method in the structure of the construction process.2. The principle and basis of construction analysis. Summarize the theoretical foundation on the simulation analysis of construction course and several numerical methods commonly used in construction mechanics, introduce the analysis principle of software MIDAS/Gen mentioned in this article, and explain the feasibility in the course simulation.3. The simulation analysis of construction course on World University games main stadium. Taking the 26th World University Games main stadium project as an example, conduct the simulation analysis of the whole process according to the actual construction of the structure, determine the feasibility of actual construction sequence and construction method, verify the accuracy of theoretical basis and finite element analysis, provide reference for the construction process.4. The comparative analysis between theoretical values and measured values. Compare and analyze the actual monitoring value in the construction process and theoretical values of the finite element numerical simulation analysis, illustrate the accuracy and practicality in the whole process of simulation analysis, obtain some valuable results, provide a certain reference for the design and construction of the large-span space steel structure.
