摘要
文中基于运动偏微分方程和等效单自由度法,开展钢筋混凝土柱在爆炸荷载作用下的动力分析,并针对固端柱塑性阶段发展过程开展了理论过程分析。通过有限元模型验证简化分析方法的有效性和可靠性。
The dynamical analysis of RC columns under blast loads was carried out based on partially differential equations of motions and equivalent single-degree-of-freedom(SDOF)models.The development of plastic hinges fora of the fixed column was analyzed with theoretical and simplified methods,whose validity and reliability were verified through the finite element model.
