The nonlinear seismic analysis of an out-of-code high-rising RC frame-core tube building

which is the highest residential building in China

is performed using multi-springs elastic-plastic finite element model.The whole seismic response process of deformation and stress from elasticity to damage and failure is studied by applying different grade earthquake load.The corrupt analysis is also studied by Push-Over method and the experimental investigation of 1/50 scale highrise building model test on 3×4 meters shaking table is described.Some measures for improving the anti-seismic capacity are advised.The results show that the weakest position of such high-rising building is between the 1/2 and 2/3 height of the building.The comparison of the results from numerical analysis with the earthquake distruction test shows a satisfactory agreement on damage and failure phenomenon.
