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.
