摘要
在文献犤1犦的基础上,编制了火灾后已修复高强混凝土柱的非线性全过程分析程序。利用这个程序,通过大量数值计算,建立了火灾后已修复高强混凝土柱剪力—位移恢复力骨架曲线特征参数,包括屈服剪力、屈服位移、最大剪力、最大位移、破坏剪力和破坏位移的统计公式,并探讨了等截面修复后柱的抗震性能变化,从而为火灾后钢筋高强混凝土框架结构的抗震性能评估及其抗震修复奠定了基础。
A program has been established for the nonlinear analysis of repaired high strength concrete (HSC) bending members after fire, and characteristic parameters have been obtained through numerical calculations for the resilience skeleton curves of shearing force and displacement of repaired HSC column after fire including statistical formulas for yield shearing force and its displacement, maximum shearing force and its corresponding displacement, collapsing shearing force and its corresponding displacement, and the seismic capability of column restored with equal dimensions was discussed as well, which will facilitate the evaluation of seismic capability of HSC reinforced framework structure after fire and seismic restoration.
