- Abstract:
- In order to study the seismic performance of the concrete stair with damping support at the lower end of the ladder slab,a 1/3-scale model structure was designed and made,and a shaking table test was carried out.By inputting different seismic waves,the damage and failure of the model were observed,and the dynamic characteristics,acceleration response,displacement response and strain response of the model were analyzed.The results show that the damping bearing stair releases the slanting effect of the stair plate,thus,changes its own force transmission path and internal force distribution.And the stair components do not fail prior to the main structure.In case of the rare earthquake,the damage of the model is light and its seismic performance is good.And the damping support has no obvious vertical warping,and the horizontal slip is small.This proves that the effective connection between the ladder slab and the platform slab can be guaranteed in case of the rare earthquake.
