摘要
利用有限元软件ANSYS/LS-DYNA,采用流固耦合的计算方法,对压型钢板组合楼板在爆炸荷载作用下进行了不同工况的数值模拟,得出压型钢板组合楼板的不同破坏模式,数值结果分析表明:在不同的工况下,压型钢板组合楼板可能发生弯曲、剪切、弯剪联合三种破坏,破坏模式与比例距离有关,随着比例距离的增大,组合板的破坏减轻。
Using finite element software ANSYS / LS-DYNA,using the calculation method of fluid-structure interaction,of profiled steel-concrete composite slab under explosion load on the numerical simulation of different working conditions,it is concluded that different failure modes of the pressed steel composite floor slab,the numerical results show that under different conditions,the composite floor slab steel sheet may be three kinds of damage： bending,shear,bending shear joint destruction,failure mode and proportion of distance,with the increase of proportion of distance,the destruction of the composite slab.
