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。
The nonlinear response caused by the interaction between built-in wall panels and frame members under the action of lateral load is studied. The numerical analysis of a large number of steel plate shear wall systems is carried out. Based on the analysis results, the influence of the built-in wallboard on the performance of the frame is discussed and its effectiveness against lateral loads is predicted. The results show that the expected buckling order can be obtained according to the design of steel plate shear wall, and the plastic deformation is mainly generated by the built-in wall panels. The study verified that the built-in wallboard was very effective in the early stages of loading (plastic deformation reaches 1% of angular displacement) and absorbs most of the interlaminar shear. However, once the slanting yield zone is present in the built-in wallboard, the panel begins to lose its effectiveness; as the yield zone progresses to the entire wall, the applied load begins to be borne by the frame members.
