| 摘 要： | 基于通用有限元软件ABAQUS,分别在准静态和动态加载条件下,对不同剪跨比和箍筋率的钢筋混凝土柱进行了数值模拟。对比现有试验结果发现,ABAQUS的模拟效果与试验结果吻合较好;加载速率的影响随着剪跨比和箍筋率的增大而降低;钢筋混凝土柱的峰值承载力随着加载速率增大而增大的趋势明显,刚度无明显变化,延性比趋于稳定。因此,在进行地震作用下钢筋混凝土结构的抗震分析时,对加载速率的影响效应要给予足够的考虑。

| Abstract: | Based on general-purpose finite element software ABAQUS,the reinforced concrete columns with different shear reinforcement ratio and shear span ratio were simulated under the quasi-static and dynamic loading conditions.It was found that ABAQUS simulation results and experimental results agreed well,the effect of loading rate reduced with the increase of shear span ratio.Similarly,the influence of loading rate also reduced with the increase of shear reinforcement ratio.The peak bearing capacity of reinforced concrete columns increased with the increase of loading rate,and there is no obvious change for the stiffness and ductility ratio.Thus,the effect of loading rate on reinforced concrete structure under seismic analysis should be given appropriate consideration. |
