| 摘 要： | 传统钢板剪力墙结构在设计时假设内嵌钢板承担100%的水平作用, 未量化考虑边缘框架的贡献, 但分析表明, 在梁柱刚接的情况下边缘框架对侧向承载力的贡献不能忽略。通过钢板剪力墙结构的塑形极限状态分析, 提出考虑边缘框架贡献的钢板剪力墙结构设计方法。对边缘框架梁(HBE)和边缘框架柱(VBE)进行受力分析, 推导考虑轴力影响的VBE截面设计公式并将其应用于考虑框架贡献的侧向承载力公式中, 确定内嵌钢板与边缘框架的剪力分配公式。通过对单层单跨的钢板剪力墙结构的算例分析, 验证剪力分配公式的适用性。最后分别采用传统设计方法和考虑框架贡献设计方法设计9层钢板剪力墙结构并对其进行非线性动力时程分析, 计算结果表明：两种方法设计的结构层间位移角均满足规范限值(1/50), 验证了该设计方法的合理性；在总用钢量方面, 采用考虑框架贡献设计的结构节省钢材6.48%, 较为经济。

| Abstract: | Conventional design of steel plate shear walls (SPSWs) assumes that 100% of the story shear is resisted by each infill panel, and the contribution of boundary frame is neglected. However, analysis results show that if the moment-resisting frame is used as boundary frame, whose contribution can not be neglected. Plastic collapse mechanisms of SPSWs subjected to lateral loads and design methods of SPSWs with moment-resisting frame were investigated in this paper. The design equation of vertical boundary elements (VBE) considering axial force was derived through mechanical analysis of horizontal boundary elements (HBE) and VBEs, and the shear distribution equation between infill panel and boundary frame was then determined. The feasibility of shear distribution equation was verified through the analysis of several one story, one bay SPSWs structures. Two 9-story SPSWs structures were designed separately by the conventional design method and the proposed design method considering boundary frame. Seismic performances were then evaluated by nonlinear time history method. For both designs, the maximum average story drifts of structures meet the requirements of Chinese seismic code, indicating the effectiveness of the proposed method. For the design using the proposed method, the total weight of steel is reduced by 6.48% compared with the conventional design, indicating the proposed procedure is more economic. |
