Abstract EN
Seismic damage of spatial structures of rectangular plan with RC substructures was observed in several earthquakes, especially in the RC substructures.
In order to reduce the seismic damage potential, a new structural configuration of spatial structure of rectangular plan is proposed, the substructures of which are composed of the steel substructure and the RC substructure.
The latter only bears the vertical load of roof by the arrangement of horizontal sliding bearings between the roof and the RC substructure.
The pushover analyses are performed on a steel braced frame and an RC frame with similar lateral stiffness, and the results show that the lateral capacity of the steel structure is much larger than those of the RC structures.
A spatial structure of rectangular plan with two different substructures is designed according to Chinese structural designing codes.
Seismic time history analyses are carried out for the spatial structure under five ground motions.
The results show that the damage mainly concentrates on the substructures, and the seismic performance of the structure with steel and RC substructures is much better than that of the structure with RC substructures.
