| 摘 要： | 工程中带缝钢板剪力墙(SPWS)由于开缝的影响,对其外覆保温、隔热和防水等材料等产生不利影响,钢板墙中部凸曲失稳而造成耗能损失,而且不便于拆换。通过参照非开缝钢板剪力墙常用的加劲形式,对SPWS中部进行"十字"加劲,并以国内某工程实例为模型进行了有限元分析。结果表明,中部加劲对SPWS的初始抗侧刚度、极限承载力、延性、耗能、面外变形和屈曲模式均有一定程度的影响,且能有效防止因倾覆弯矩而导致的边缘小柱提前屈曲。中部加劲能调节SPWS刚度分布、减少面外变形、提高延性和耗能性能的效果,可为工程设计提供参考。

| Abstract: | The characteristics of a steel plate shear wall with slits(SPWS) and the reason of middle-stiffening in SPWS are introduced here. The conclusion from the study for the finite element model of a domestic project indicates that the middle-stiffening has a certain impact on the initial lateral stiffness,ultimate bearing capacity,ductility,energy dissipation,out-of-plane deformation and buckling mode of SPWS,and can also prevente the advanced buckling of edge column because of the overturning moment.These may b... |
