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

Abstract

This article presents analytical, numerical, and experimental studies on the in-plane stiffness of container buildings. First, based on diaphragm theory, parallel corrugated direction stiffness of corrugated sheet has been deduced, and based on energy method, shear modulus of two elastic principal directions of orthotropic plate has been deduced, and through stiffness conversion method, the stiffness relationship between parallel corrugated direction and vertical corrugated direction has been obtained. Combined with container frame, the container stiffness of loading end and non-loading end, as bottom side beam fixed, has been obtained. Second, through the software Abaqus, full-scale container model has been established. The loading-displacement curve of finite element model has been compared with theoretical analysis and has a good agreement. Third, through 20 and 40 ft container, corresponding experimental verification has been done, and by comparison of container stiffness, the theoretical analysis and finite element simulation have been verified. Finally, based on verified finite element model, parametric analysis of corrugated sheet size, corrugated sheeting cross section, elasticity modulus of top side beam, and every plate action for container stiffness have been given. Research result has made feasible in design and construction of container buildings and can provide some references to corresponding specification preparation.

Shipping Container as Shelter Provision Solution for Post-Disaster Reconstruction

“…In 2016, two researchers from China had developed the theoretical stiffness of a container with and without opening on wall panel [19,20]. By using diaphragm theory, they had developed the formulation for the stiffness of corrugated wall on container.…”

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

“…Thus, the stiffness of the corrugated sheeting with holes can be superimposed through the preceding analysis. The deformation of the container side wall is coordinated under external loading; thus, the displacement of the container can be expressed as equation (19) f…”

“…x Ck are the loading distribution coefficients between W area i, D area j, and C area k, respectively; and k OWCSi , k ODCSj , and k OCCSk are the stiffness of W area i, D area j, and C area k, respectively. Thus, equation 20can be obtained according to equation (19) x…”

“…Finally, five experimental studies of container with holes were verified. Zha and colleagues [17][18][19] proposed the formulae of container stiffness as the single layer and multi-span, multilayer and single-span, and multi-layer and multi-span based on the principle of displacement coordination and diaphragm theory. Then proposed a new isolation system based on friction energy between containers, and the relationship between equivalent damping ratio and friction coefficient of sliding isolation structure had been gotten.…”
