外剪内框结构体系力学计算与抗震性能
Mechanical calculation and seismic behavior of frame structural system coupled with exterior-shear-wall
摘要
Abstract
For the purpose of achieving large inner architectural space in a shopping mall or warchouse,a frame structural system coupled with exterior-shear-wall(ESIF)is proposed.ESIF consists of a exterior-shear-wall resisting lateral effects and a interior-frame carrying vertical loads.The calculation method of ESIF is deduced.The design formula and scheme of relative stiffness between the frame and the shear wall are given.Based on a four-story frame structure,the corresponding ESIF is designed.The seismic behavior and anti-collapse performance are evaluated.The results show that ESIF can achieve larger inner architectural space with smaller section of interior-frame columns than traditional frame structures.Design scheme of the stiffness between frame and shear-wall can be applied in practical engineering.ESIF has superior seismic behavior and anti-collapse performance with the increase of the lateral stiffness by 30.3%and the ultimate capacity by 7.3%,and the decrease of the base-shear-forcing by 13.8%,the top-story displacement by 66.3%and the maximum inter-story drift by 74.3%,comparing with traditional frame structures with the same material cost.关键词
