摘要:
运用ANSYS/LS-DYNA软件分别建立了钢筋混凝土柱、汽车、炸药及空气等模型，对模型的有效性进行了模拟验证；采用全过程分阶段数值模拟方法研究了不同参数对钢筋混凝土柱动力响应的影响，并对柱的破坏模式进行了分析。结果表明：汽车速度、炸药量的增加都会不同程度地加大柱中水平位移；柱截面惯性矩及箍筋配筋率的增加均对柱的抗冲击能力有不同程度提高；混凝土轴心抗压强度和纵筋配筋率的提高虽然使柱中水平位移有所降低，但在一定范围内降低值并不是很大；柱的破坏模式主要包括局部破坏、整体弯剪破坏和整体剪切破坏。
Abstract:
The models of reinforced concrete column, vehicle, explosive and air were established by software ANSYS/LS-DYNA, and the validity of the models was verified by simulation. The influence of different parameters on the dynamic response of reinforced concrete column was studied by using the whole process staged numerical simulation method, and the failure modes of the columns were analyzed. The results show that the increases of vehicle speed and explosive quantity will increase the horizontal displacements in the middle of column. The increases of column section inertia moment and stirrup ratio can improve the impact resistance of the column. Although the increases of axial compressive strength of concrete and longitudinal reinforcement ratio can decrease the horizontal displacements of column, but the reduced values are not very large in a certain range. The failure modes of the column mainly include the local damage, the whole bending shear failure and the whole shear failure.
