【 摘 要 】

In this paper, three-dimensional degenerated virtual laminated element nonlinear finite element method is utilized to simulate the whole process of vertical anti-continuous collapse of ten-storey RC frame structure with nine-palace lattice under the failure of the bottom corner columns. It can be found that the axial force redistribution of the same story column shows relationship with the load range and the distance from the failure column. Besides, the integral collapse resistance mechanism and the axial force of the vertical column of the failure column are different from that before failure.
