【摘要】 通过对仅与框架梁连接的两边连接钢板剪力墙在往复荷载作用下的试验,探讨了其滞回特征和耗能能力.结果表明该类剪力墙具有较高的初始刚度和承载力,受荷后期沿对角线形成拉力带,利用屈曲后性能承担荷载并耗能,具有稳定的耗能能力,延性系数超过5.0,符合现行国家规范的设计要求.采用有限元分析方法研究了钢板高厚比和跨高比对骨架曲线的影响,提出了便于应用的骨架曲线简化模型和计算方法.更多还原

【Abstract】 The steel plate shear wall with two-side connections,only connected with boundary frame beams,was tested under cyclic loading to discuss its hysteresis property and energy dissipating capacity.The results show that the shear wall has high initial stiffness and strengtht;hat will diagonal tensile field formed at the later loading stage,the shear wall sustain lateral load and dissipate energy due to its post-buckling capacity;that the ductility coefficient of the shear wall is over 5.0,which meets the requirment of the current Chinese design codes.In addition,the finite element method(FEM)was used to study the influence of height-to-thickness ratio and length-to-height ratio on the skeleton curve.The simplified model and design methods to predict the skeleton curve were put forward for practical application.更多还原
