Theoretical and experimental studies on in-plane stiffness of container structure with holes

In practical engineering, the container building usually has an opening and stiffening process to meet the requirements of architectural design. So, the stiffness of the container with holes has been studied and stiffening member has been considered in the process of container stiffness enhancement. First, based on the paper “Theoretical and experimental studies on in-plane stiffness of integrated container structure,” the stiffness of corrugated sheet with window, door, and combined window has been derived and then the stiffness of corrugated sheet with above-mentioned holes has been derived. Thus, through stiffness distribution between frame and corrugated sheet, the stiffness of container with holes has been derived. Second, through finite element software of Abaqus, full-size container model with holes has been established and combined with stiffening members. Through simulation, the load–displacement curve has been got and then compared with theoretical analysis. Finally, through full-size 20- and 40-ft containers with holes and stiffening members, corresponding experimental verification has been done, and by comparison of load–displacement curve with theoretical analysis and finite element simulation, the front study has been verified. Research result has made feasible in design and construction of container building and provided some references to corresponding specification preparation.
