半刚性框架-屈曲约束钢板剪力墙结构振动台试验研究
Shaking table test of semi-rigid frame with buckling-restrained steel plate shear walls
摘要
Abstract
A 1 /3 scaled one-span four-story semi-rigid steel frame with buckling-restrained steel plate shear wall was tested on the shaking table to research the seismic performance of this structure. The El Centro wave,Taft wave and an artificial wave were selected as the simulated earthquake input. The dynamic characteristics and response of the specimen were analyzed for 8 cases under the horizontal earthquake action from frequent earthquake level of 7 degree fortification intensity to rare earthquake level of 9 degree fortification intensity,respectively. The research results show that the specimen has no obvious plastic deformation under frequent earthquakes. Most of the wallboards in the grid at the first and third stories form tension belt under rare earthquakes. The lateral stiffness is degraded gradually with the increase of earthquake excitation,and the maximum decrease is only 12％ under rare earthquake level of 9 degree fortification intensity. The buckling-restrained steel plate shear walls enter elasto-plastic phase firstly as the initial seismic fortification line and can avoid the damage of the frame through absorbing and dissipating seismic energy. The maximum inter-story drift ratio of the structure is 1 /476 and 1 /68 under frequent earthquakes and rare earthquakes respectively,both meeting the inter-story drift ratio limits required in the current seismic design code of buildings. The structure has good seismic performance and can satisfy the two-phase and three-level seismic fortification requirements.关键词
