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

为了保证结构墙体的延性破坏模式，使其成为一种经济的地震反应控制体系，对Mo和Perng于2000年提出的波纹钢板剪力墙混合体系进行了修正，使其在实际工程中能有效地耗散地震能量。通过对波纹钢板剪力板混合体系的修正，证明了波纹钢板剪力板的抗剪承载力和抗剪刚度在周围钢筋混凝土构件与剪力板之间有足够的锚固作用的情况下得到了充分利用。在试验阶段，一个螺栓型锚具经常使用的桥梁箱梁采用四个半比例的标本和静态循环荷载的应用。如果螺柱的数量满足日本设计指南，则行为稳定。波纹板屈曲后的行为是延性的，即使在5%的偏移角下，横向承载能力的退化也约为20%。然而，即使是一半数量的螺柱的标本也表现出类似的行为。所有混合框架的横向承载能力比原钢筋混凝土框架提高了30%以上。在分析阶段，进行了非线性框架分析，以评估波形钢剪切板对钢筋混凝土框架性能的影响。分析结果较好地模拟了不同剪力板固接情况下框架的受力性能。利用该分析模型，建立了考虑框架和波纹钢板抗剪承载力的锚固量优化设计方法。

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.
