摘要
传统抗弯构架加入耐震间柱后可使刚度、强度与韧性获得提升，因此可设计为新建筑的抗震系统或既有建筑的补强。本文探讨一种中间段以低屈服强度钢材为腹板，高强度钢为翼板，上下段皆以高强度钢制成之三段式剪力屈服型耐震间柱。本文井使用非线性分析程序探讨耐震间柱的受震反应，并与一般抗弯构架作比较。由分析中可发现，楼层位移角及侧向位移均有显著的减小，其塑铰也由梁端成功地转移全间柱上。而耐震间柱的确也肩负起消能的责任，使得在地震发生时能消释构架中大部分的迟滞能量．
Adding supplemental shear panels to the traditional moment resisting frame can enhance the system stiffness, strength and ductility capacities. This paper presents the analytical and experi- -mental research results of applying the hybrid steel shear panels consisting of low yield strength web and high strength flanges. Research results indicate that the hybrid shear panel possesses stable ener- gy dissipation characteristics and can effectively reduce the nonlinear rotational demands imposed on the beam...
