基于ABAQUS的型钢超高强混凝土短柱抗震延性的研究

Study on Seismic Ductility of Section Steel Ultra-high-strength Concrete Short Columns Based on ABAQUS

为研究型钢超高强混凝土短柱的抗震延性,基于已有的3根型钢超高强混凝土短柱在低周反复荷载作用下的延性试验研究,运用大型有限元分析软件ABAQUS模拟其骨架曲线,并与试验结果进行比较。结果表明,模拟得到的荷载位移曲线与试验结果吻合较好,该方法可以较为准确地预测试验结果,验证了该有限元模型的适用性。

To study the seismic ductility of section steel ultra-high-strength concrete short-columns,the finite element program ABAQUS is used to simulate the skeleton curves of three section steel ultra-high-strength concrete short-columns under axial force and cyclical loading.Through comparative study,it is found that the calculation and experiment show good agreement,which proves that the proposed finite element model is suitable for section steel ultra-high-strength concrete short-columns.
