Scheme comparison of long and narrow plane of vertical slender height structure in highly seismic region
It is crucial to design long and narrow plane of vertical slender height structures in highly seismic region,so it is very important to select suitable lateral force resistant structure system.For a high-rise structure in Haikou,based on four structural schemes including reinforced concrete frame-shear wall,reinforced concrete shear wall,steel frame and concrete-filled steel tube frame-steel plate combined shear wall,YJK and Perform-3D software were used to compare and analyze the dynamic characteristics,elastic response under small earthquakes,elastic-plastic response under large earthquakes and seismic performance of each scheme.The economy and comfort of the four structural schemes were compared and analyzed.The results show that the interlayer displacement angle for small earthquake of reinforced concrete shear wall scheme is slightly larger than the limit,and all schemes meet the limit of interlayer displacement angle for small earthquake and large earthquake.The bottom shear force and total input energy of steel frame,concrete-filled steel tube frame and steel plate composite shear wall schemes are significantly reduced under earthquake,and the ductility of the components is better.The concrete filled steel tube frame-steel plate composite shear wall structure has the best economy,the largest net use area of the building,the highest net height under the beam,and the shorter construction period,which meets the requirements of prefabricated building.
