- W2382149287 abstract "Finite element models are developed by using the explicit dynamic analysis nonlinear finite element procedure LS-DYNA,with simulation of the impact responses and failure modes of steel frame columns,to analyze failure modes of steel frame columns and influencing factors under three kinds of blast loading.The results show that the shell element approach is found to predict the effects of local buckling of cross section occurred after the blast loads,and can effectively simulate the impact responses and failure modes of steel frame columns.In the case of the same peak pressure,the longer the duration time,the greater the structural deformation.In the case of the same impulse load,the higher the peak pressure,the more serious the structure damage.It is found that the failure modes of steel frame column under blast loading depend on the blast loading type.The steel frame columns tend to cause shear failure of column base and the flange buckling failure in the middle of columns under impact load;they also tend to cause shear failure of column base under dynamic load;flexural buckling failure of column is liable to be caused under quasi-static load." @default.
