Analysis on seismic behavior of different structural systems of small high-rise buildings

In order to study the seismic performance of small high-rise building under different structural systems, an ordinary residential tower building of 11 floors in 7 degree area was designed as a frame structure, frame-shear wall structure and shear wall structure respectively. Elastic calculation of all structures was conducted based on FE model built by the software of YJK and elasto-plastic time-history analyses were conducted by the software of PERFORM-3D. The numerical results confirm that all of the three kinds of structure system can meet the requirement that the beam yield firstly, but vertical force component dose not yield in rare earthquake. On the frame-shear wall structure, the inter-story drift angle can be controlled better. The proportion of plastic energy dissipation of the frame structure is the highest and of the shear wall structure is the least among the three structures. All kinds of structure systems show good seismic behavior.
