ABSTRACT

The steel roof of Jiangmen gymnasium is the large-span spatial pipe truss structure, which is composed of main truss, secondary truss and stable truss. This paper systematically expounds the construction simulation analysis, the composition of the construction monitoring system, the monitoring method, and the arrangement of measuring points. The construction simulation analysis simulates the whole process of the main truss cumulative lifting installation, the secondary truss and auxiliary structure hoisting, and then the main truss for overall unloading, which is the difficulty of the whole project. The results of the structural construction monitoring show that the roof structure is in a safe state, and the fine construction simulation analysis provides a theoretical basis for the construction process, and the theoretical value of the simulation analysis is in good agreement with the measured data. In addition, vertical displacement and stress are obvious mutations in the unloading stage of roof support, but the stress of each measuring point is in elastic working condition, which meets the design requirements, indicating the correctness of the model and method in construction simulation analysis and calculation, and also provides reference for the design and construction of related projects in the future.
