钢板剪力墙结构中墙-框架交互作用的特性分析

研究了钢板剪力墙(SPSW)双系统在侧向荷载作用下,由内置墙板与框架构件之间相互作用而引起的非线性反应。对大量钢板剪力墙系统进行了数值分析,基于分析结果讨论了内置墙板对框架性能的影响,并对其抵抗侧向荷载的有效程度进行了预测。结果表明:依据设计规范设计的钢板剪力墙可以获得预期的屈曲顺序,且塑性变形主要由内置墙板产生。研究验证了内置墙板在加载的初期是非常有效的(塑性变形达到角位移的1%),并且可以吸收大部分层间剪力。然而,一旦内置墙板中出现了斜向屈服区,墙板便开始丧失其有效性;当屈服区发展到整面墙的时候,外加荷载便开始由框架构件承担。

Characteristics of the Wall-Frame Interaction in Steel Plate Shear Walls

The nonlinear response of steel plate shear wall (SPSW) dual systems under lateral loading with regard to the interaction between the infill plates and frame members is studied.A number of SPSWs are numerically analyzed and the results are utilized to discuss (a) the influence of infill plates on the behavior of frames and (b) to evaluate their degree of effectiveness in resisting lateral loads.Results show that SPSWs designed according to design codes should have desirable sequences of yielding and that pl...
