波纹钢板剪力墙抗震性能试验研究

提出一种新型钢板墙-波纹钢板剪力墙。设计了两个不同形式的波纹钢板剪力墙试件，采用低周往复加载试验，分析二者的破坏形式，对滞回曲线、骨架曲线、延性、刚度及耗能性能等性能进行了系统的研究。研究表明：两种波纹钢板剪力墙均具有较高的极限承载力及初始刚度；屈曲承载力较高，屈服位移较小，能够较快地进入塑性耗能；滞回曲线较为饱满，不易发生捏缩现象。与横向波纹钢板剪力墙相比，竖向波纹钢板剪力墙的滞回性能及屈服后承载力更加出色。结果表明，在合理的参数设计下，所提出的波纹钢板剪力墙承载力高、耗能性能较强，是一种极具前景的新型抗侧力构件及耗能构件。

Experimental investigation on performance of corrugated steel plate shear wall

In this work, a novel steel plate wall-corrugated steel plate shear wall is proposed. Two different forms of corrugated steel damping wall specimens have been designed and manufactured. The failure modes of two corrugated steel damping wall specimens are studied at low-frequency cyclic loading test, then hysteresis curve, skeleton curve, ductility, stiffness and energy dissipation performance are investigated systematically. The test results indicate that, both corrugated steel damping walls have high ultimate bearing capacity and initial stiffness, whose buckling bearing capacities are relatively high and  yield displacements are relatively small. Thus the proposed novel damping wall can be apt to plasticity range. The hysteretic curve is relatively plump with less shrinkage. As compared with horizontal corrugated steel, vertical corrugated steel plate shear wall shows higher post-yield bearing capacity and possesses more remarkable hysteretic performance. Test results demonstrate that the proposed corrugated steel plate shear wall, which can have high shear capacity and energy dissipation ability with the proper design of parameter, may have a broad prospect as a new lateral force resisting member and energy dissipation device in the near future.
