Analysis of longitudinal stiffness of container building structure with holes

Since container buildings are widely used nowadays, this paper attempts to make a study on the longitudinal stiffness of container with holes under external load. Firstly, by applying diaphragm theory, a mechanical analysis and stiffness calculation method of container with holes were given, followed by examples to illustrate the calculation process. Then, through nonlinear finite element software of ABAQUS, a finite element model of container was established. Based on the area and aspect ratio of the hole, a parametric analysis was given to obtain the influence law of parameters on the stiffness of container with holes and some suggestions about the design were followed. Finally, five experimental studies of container with holes were conducted, and both the theoretical and finite element simulation results were compared with experimental data, which were in good agreement. The research result can offer some references not only in the design and construction of container buildings, but also in the description of relevant norms.
