超高强混凝土柱抗震性能数值模拟

Numerical simulation on ultra high-strength concrete columns in seismic performance

基于超高强混凝土柱低周反复荷载试验的结果,利用大型有限元分析软件ANSYS,建立了不同剪跨比,不同配箍率的超高强混凝土柱的计算模型,并对其进行了在不同轴压比条件下低周反复荷载全过程非线性有限元分析,得到了混凝土柱的滞回曲线、骨架曲线。将滞回曲线、骨架曲线计算结果与试验结果进行对比,发现吻合较好。

Based on the low-cycle reversed loading tests, the ultra high-strength concrete columns of different shear span ratio and different stirrup reinforcement were modeled with ANSYS software;The low-cycle reversed loading tests on condition of different axial load ratio were non-linearly simulated.The hysteretic curves, skeleton curves were obtained.The calculated hysteretie curves and skeleton curves were corresponding well with experimental results.
