发布时间：2019-02-15 03:55
【摘要】：为改善结构柱抗冲击性能,提出最优截面形式,对不同截面的新型复合柱进行了抗冲击试验研究,并基于3种通用动力非线性有限元软件MSC.Marc、ABAQUS和ANSYS/LS-DYNA对撞击试验进行了数值模拟。试验结果表明新型复合柱的整体抗冲击性能较好;在相同外径和用钢量下,实心夹层钢管混凝土抗冲击性能最佳,空心夹层钢管混凝土抗冲击性能次之,内插双H型钢钢管混凝土稍差。ABAQUS建立的有限元模型和试验结果吻合最好,MSC.Marc次之,ANSYS/LS-DYNA稍差。研究结果可为新建大型铁路站房柱抗冲击选择最优截面提供依据,并为选取适合的有限元软件进行抗冲击分析提供参考。
[Abstract]:In order to improve the shock resistance of structural columns, an optimal section form is proposed. The new composite columns with different cross-sections are tested and studied. Based on three kinds of general nonlinear finite element software MSC.Marc, the impact resistance of composite columns with different sections is studied. The impact test was simulated by ABAQUS and ANSYS/LS-DYNA. The experimental results show that the whole impact resistance of the new composite column is better. Under the same external diameter and steel content, the impact resistance of solid sandwich concrete filled steel tube is the best, and that of hollow sandwich steel tube concrete is the second. The finite element model established by ABAQUS is in good agreement with the experimental results, followed by MSC.Marc and ANSYS/LS-DYNA. The results can provide the basis for selecting the optimal section of the columns of the new large railway station and provide a reference for the selection of the appropriate finite element software for the anti-impact analysis.
