Numerical Analysis on Pounding Superstructures with Shock Absorber

Abstract eng:
In this paper, we carried out numerical analyses on pounding superstructures, which consist of concrete floor slab and steel girder, by using the 3-dimensional finite element method. To be more precise, the maximum impact force is calculated when the installation site of the natural rubber are changed. In addition, the damage of the superstructure ends is investigated. From the numerical analyses, the damage of the superstructure varies widely depending on the installation site of the natural rubber. The steel girders yield even if the natural rubber is installed when the collision velocity becomes faster. Moreover, the edge of the concrete floor slab is also cracked even if the natural rubber is installed in front of the concrete slab. It is difficult to replace a damage member of the steel girder. Therefore, from the perspective of the damage control, it is thought that installation of the rubber at the concrete floor slab end is much better.
