横向冲击荷载下钢管混凝土柱承载性能研究

Research on bearing performance of concrete-filled steel tubular column under horizontal impact load

对横向冲击荷载下的两端固支钢管混凝土柱承载性能进行数值仿真分析,在此基础上分析了构件重点部位的应力、应变时程曲线以及塑性铰形成与变化过程,结果表明,横向冲击荷载下两端固支钢管混凝土具有良好的塑性变形能力和较好的抗冲击力学性能。

The paper carries out numerical simulation analysis on the bearing performance of steel-tube concrete column on the both sides under horizontal impact load, and analyzes the stress, stress time-history curve, and formation and changing process of plastic hinge of important structural parts. Results show that： the fixed steel-tube concrete on both sides has great plastic deformation capacity and better impact-resisting mechanical performance under horizontal impact load.
