Abstract

Abstract

The analysis model of four-sided simply-supported thin plates with rectangular holes subjected to linearly varying loads was constructed by using the finite element software ABAQUS. The influence of dimension and spacing of holes on the elastic buckling property, buckling coefficient, and ultimate bearing capacity of perforated thin plates subjected to linearly varying loads was analyzed. The elastic buckling analysis results show that the effect of the spacing of holes was not significant when the spacing of holes could meet a certain limit. With the increase of the dimension of holes, buckling modes of thin plates transformed from the buckling of plates with holes to the buckling of plates adjacent to holes. Finally, buckling coefficients of thin plates with rectangular holes subjected to linearly varing pressure were obtained by finite element analysis. Meanwhile, the calculated formula of buckling coefficients was proposed. The ultimate bearing capacity of thin plates was calculated by using effective width method based on proposed buckling coefficients that the dimensions of rectangular holes had less effect on the ultimate bearing capacity of perforated plates when holes were small. But the effect gradually increased with the increase of dimensions of holes. The proposed effective width method could be used to predict the ultimate bearing capacity of thin plates with rectangular holes subjected to linearly varying loads.
