Abstract:The basement of City Stadium of Tianshi College is one integrated unit, and concrete structure on the ground is divided into five independent units through five permanent structural joints. The roof steel structure is 380 meters long from north to south without structural joints, and five independent units form connected structures through the roof steel structure. The roof steel structure consists of single-layer reticulated shell system and two-way orthogonal truss system is used in part of gymnasium roof. The structural system and project features were introduced in detail. The temperature stress was analyzed in the super-long concrete structure. The performance-based seismic design process of the structure was introduced in detail. The influence of traveling wave effect on the super-long steel structure and surrounding vertical concrete members was studied by multi-point and multi-dimensional time history analysis. The dynamic characteristics and seismic performance of the structure were studied by dynamic elastic-plastic time-history analysis under rare earthquake. Results show that the structure can meet the seismic performance objectives.
Keywords:City Stadium of Tianshi College; single-layer reticulated shell; super-long structure; multi-point and multi-dimensional time history analysis; elastic-plastic time history; connected structure
