【摘要】 通过2榀低屈服点钢筋和1榀普通钢筋的两层两跨RC框架低周反复加载试验,对结构的破坏形态、破坏机制、滞回曲线、骨架曲线、位移延性、刚度退化、耗能能力等抗震性能进行了较为深入系统的研究。研究表明,与普通RC框架相比,在相同水平承载力情况下,低屈服点钢筋RC框架具有延性性能好、变形能力大、刚度退化趋缓、耗能能力强的特性,可见,低屈服点钢筋RC框架具有更优的抗震性能。更多还原

【Abstract】 The seismic performances such as failure pattern,failure mechanism,hysteresis curves,displacement ductility,rigidity degradation and energy dissipation of two pieces of low yield point steel reinforced concrete frames with double-story and double-span and one ordinary reinforced concrete frame with double-story and double-span were studied systematically by testing of low reversed cyclic loading.The results show that the level of capacity in the same circumstances,compared with ordinary RC frame,low yield point steel reinforced concrete frame has some good characteristics such as better ductility,higher deformation capacity,slower stiffness degradation,and larger energy dissipation capability,which show that seismic performance of low yield point steel reinforced concrete frame is more excellent.更多还原
