项目摘要

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.

为了通过确保结构墙的延性破坏模式来建立经济的地震反应控制系统，对Mo和Perng于2000年提出的波纹钢剪力板混合系统进行了修改，使其在实践中有效地消散地震能量。本文对波纹剪力板混合结构进行了修正，证明波纹钢剪力板的抗剪能力和抗剪刚度得到了充分发挥，且在周围钢筋混凝土构件与剪力板的界面处有足够的锚固。在试验阶段，在4个半比例尺试件上采用了箱梁常用的桩式锚固，并进行了静力循环加载。如果螺柱的数量满足日本的设计准则，那么这种行为是稳定的。波纹板屈曲后表现出延性，即使在5%的偏航角下，其横向承载能力也下降了20%左右。然而，即使只有一半种马的标本也表现出类似的行为。所有混合动力框架的横向承载能力都比原始RC框架提高了30%以上。在分析阶段，进行了非线性框架分析，以评估波纹钢剪力板对钢筋混凝土框架性能的影响。分析较好地模拟了剪力板不同固定度下框架的受力情况。利用该分析模型，建立了框架和波纹钢板抗剪承载力锚固量优化设计方法。
