Study on the mechanical properties of stiffening members on the container structure with holes

In order to study the influence law of stiffening members on the reinforced mechanical properties of container structure with holes, this study conducted full-scale experiments, finite element simulations, and theoretical calculation methods for the mechanical properties of reinforced container structure with holes. The experimental parameters included the opening area, the stiffening members, etc. The research results showed that: (1) The opening area had a significant impact on the load-displacement curve, stiffness, and deformation of stiffening members. Compared with intact container, the corresponding stiffness reduction rates of 40OR-1W, 40OR-3W, and 40OR-5W were 17.75 %, 36.67 %, and 50.58 %; (2) The finite element simulation and experimental results were in good agreement, and the error of the load-displacement curve and the stiffness value were around 3 %; (3) More importantly, this study innovatively proposed a theoretical calculation method for stiffening members, which predicted the deformation of stiffening members effectively. The calculation theory had a good consistency with experimental values. This research results provided more comprehensive understanding of the influence law of stiffening members on the reinforced mechanical properties of container with holes. In addition, the innovative theoretical calculation method of stiffening members established in this study provided an important theoretical guidance for the container building. This research result provided design and construction suggestions for widely used container building today, and provided reference for the formulation of corresponding specifications.
