FEM and experimental study on mechanical property of container building with holes

Based on the finite element simulation and the experimental verification, the stiffness of container building with holes is studied. Firstly, through finite element software of the Abaqus, 20ft and 40ft container model are established, and the corresponding holes and stiffening members are considered. Through simulation, the stiffness and Mises stress contour of the container model are got. Secondly, a full size experiment of container with holes is studied, and then, through comparison of the loading-displacement curves and the loading-stress curves with finite element simulation, the finite element model is verified. Finally, based on the verified finite element model, the influence laws of the hole and the stiffening member is given, and the relevant design recommendations of the hole position, the hole area, the hole size ratio and the stiffening member form are given. Research results make feasible in design and construction of the container buildings and provide some references to the corresponding specification preparation.
