摘　　要：为研究实际钢结构住宅项目中钢板剪力墙最真实的抗震性能和外包装饰层的变形能力,设计了4榀足尺钢管混凝土框架-竖向加劲钢板剪力墙试验构件,对受竖向荷载作用下的钢板剪力墙试件进行了拟静力试验,对比研究了外包装饰层、竖向加劲肋布置方式对钢板剪力墙结构抗震性能的影响。研究结果表明:在竖向荷载和水平往复荷载共同作用下,钢板剪力墙试件仍具有较高的承载力,优良的耗能性能和延性。钢板剪力墙外包的砌体装饰层可提高钢板剪力墙在地震作用下的初始刚度与耗能能力,但会加快试件达到峰值荷载后承载力的退化,而对钢板剪力墙构件的峰值荷载、延性系数以及刚度退化并无显著影响。竖向加劲肋等距布置的钢板剪力墙峰值承载力略高于不等距布置的试件,而两种加劲肋布置方式对试件其他方面的性能影响较小。在试验和已有文献的基础上,提出了应用于该类贴砌式外包装饰层钢板剪力墙在地震作用下的有害位移角分级方法。To study the seismic performance of steel plate shear wall and the deformation capacity of the outer decorative layer in the steel structure residence, four test components of the full-scaled concrete-filled square steel tubular frame-steel plate shear walls with vertical stiffeners were tested under constant vertical load and cyclic lateral loads. Through quasi-static hysteresis loading of each specimen, the influence of the outer decorative layer and vertical stiffener arrangements on the seismic performance of the steel plate shear wall was discussed. High bearing capacity, favorable energy dissipation capacity and ductility of all specimens were found even under the combined action of vertical load and horizontal repeated load. The outer decorative layer could improve the initial lateral stiffness and the energy dissipation capacity during the early stage, but speed up the degradation of the capacity in the post-peak stage. No other significant difference was found between the specimens with or without the outer decorative layer. The peak loads of specimens with equidistant arrangement of vertical stiffeners were slightly higher than that with the uneven distant arrangements of stiffeners, and the other seismic behaviors of both were almost the same. On the basis of experiments and existing literature, the classification of harmful displacement angles for steel plate shear walls with outer decorative layer was proposed.
