摘要
基于ANSYS有限元分析软件,对钢筋混凝土柱在侧向撞击作用下的动力响应进行了数值模拟分析。运用参数化分析方法,研究了截面惯性矩、混凝土抗压强度、纵筋配筋率和箍筋间距等参数对钢筋混凝土柱中节点位移的影响。计算结果表明:增加纵向配筋率与截面尺寸可以显著降低柱中节点位移,而增加箍筋配筋率的效果不明显。
Based on the finite element analysis software ANSYS, the dynamic responses of RC columns under lateral impact are analyzed. Parametric studies are adopted to investigate the influence of cross section dimension, concrete strength, longitudinal and transverse reinforcement ratio on the dynamic responses of RC columns. Compution results show that the influence of longitudinal reinforcement ratio and cross section dimension could reduce the midspan dynamic drift, but the influence of stirrup ratio does not have obvious effect on the dynamic response.
