The cable-net dome system is the first to adopt a new structure form in China, the system is more complex, the static and dynamic analysis and the dynamic simulation of the construction process are particularly important. Based on the nonlinear finite element analysis method, the cooperative performance of the structure's primary and secondary cable network is analyzed, and the dynamic performance is deeply discussed. In view of the difficulties in the construction and forming of cable dome structure, using ANSYS software to track and simulate the structural response in the construction process has certain reference value for the engineering construction design of similar structures.
