The steel frame reinforced with steel shear wall is a lateral load resisting system and has higher strength and shear performance than the concrete shear wall system. Especially, using corrugated steel plates in these shear wall systems improves out-of-plane stiffness and flexibility in the deformation along the corrugation. In this paper, a cyclic loading test of this steel frame reinforced with trapezoidal-corrugated steel plate was performed to evaluate the structural performance. The hysteresis behavior and the energy dissipation capacity of the steel frame were also compared according to the corrugated direction of the plate. For the test, one simple frame model without the wall and two frame models reinforced with the plate are considered and designed. The test results showed that the model reinforced with the corrugated steel plate had a greater accumulated energy dissipation capacity than the experimental result of the non-reinforced model. Furthermore, the energy dissipation curves of two reinforced frame models, which have different corrugated directions, produced similar results.
钢框架加钢剪力墙是一种抗侧力体系，其强度和抗剪性能比混凝土剪力墙体系更高。特别是，在这些剪力墙体系中使用波纹钢板可提高平面外刚度以及沿波纹方向变形的灵活性。本文对这种梯形波纹钢板加固钢框架进行了循环加载试验，以评估其结构性能。还根据钢板的波纹方向比较了钢框架的滞回性能和能量耗散能力。对于该试验，考虑并设计了一个不带墙的简单框架模型和两个用钢板加固的框架模型。试验结果表明，波纹钢板加固模型比未加固模型的试验结果具有更大的累积能量耗散能力。此外，两个波纹方向不同的加固框架模型的能量耗散曲线产生了相似的结果。
