Use of corrugated steel shear panel in reinforced concrete building structures as a main lateral force resisting component

为了通过确保结构墙体的延性破坏模式来建立经济的地震反应控制体系，对Mo和Perng在2000年提出的波纹钢剪力板混合体系进行了修正，使其在实际应用中能够有效地耗能。本文对波纹剪力板混合体系进行了修正，充分利用了波纹钢剪力板的抗剪能力和抗剪刚度，并在周边钢筋混凝土构件与剪力板的界面处设置了足够的锚固力。在试验阶段，对四个半比例试件采用了桥梁箱梁常用的螺纹式锚具，施加静力循环荷载。如果螺柱的数量满足日本的设计指南，行为是稳定的。波纹板屈曲后的性能表现为延性，即使在5%的漂移角时，其横向承载能力也有约20%的退化。然而，即使是螺柱数量减半的样本也表现出类似的行为。所有混合框架的水平承载能力都比原框架提高了30%以上。在分析阶段，对波纹钢剪力板对钢筋混凝土框架性能的影响进行了非线性框架分析。分析结果较好地模拟了不同剪力板固定度框架的受力性能。在此分析模型的基础上，建立了框架和波纹钢剪力墙的抗剪承载力优化设计方法。

In order to make an economical seismic response controlling system by securing a ductile failure mode of structural walls, a hybrid system using corrugated steel shear panel proposed by Mo and Perng in 2000 was revised to make it effective in dissipating seismic energy in practice. In this study, the hybrid system with corrugated shear panel was revised to prove that the shear capacity and the shear stiffness of corrugated steel shear panels were fully utilized with sufficient anchorage at the interface between surrounding RC members and shear panels. In an experimental phase, a stud-type anchorage often used in bridge box girders was employed in four half-scale specimens and static cyclic loading was applied. The behavior was stable if the number of studs satisfied the Japanese design guidelines. The behavior after buckling of the corrugated panel was ductile and degradation in lateral load carrying capacity was about 20% even at 5% drift angle. However, even specimens with half number of studs showed the similar behavior. All hybrid frames showed more than 30% increase in lateral load carrying capacity from the original RC frame. In an analytical phase, a nonlinear frame analysis was conducted to evaluate the effect of corrugated steel shear panel on the performance of the reinforced concrete frame. The analysis simulated the behavior of frames with different fixity of the shear panels well. Design method to optimize the amount of anchorage due to shear capacity of frames and corrugated steel shear panels is established with this analysis model.
