Abstract:

In the construction industry, various types of structures are used i.e. moment resisting frame and flat plate structures. The latter one is more advantages, and thus become more popular. These structures when subjected to earthquake or lateral loading, cause high shear stress in slab column joint and shear failure occurred when shear stresses exceed their limit. The purpose of this paper is to study two parameters i.e. slab thickness and column dimensions influencing punching shear stress developed at column slab joint. For this purpose, various models with variations in dimensions are considered. The model consisted of reinforced concrete flat plate structures of six stories. After push-over analysis of proposed models punching shear stresses at three points (corner, intermediate, and edge) of column slab joint in flat plate structure are achieved. Based on the above results, it is concluded that the increase in punching shear is observed keeping width same and increase column depth, thus directly proportional. More ever, with an increase in slab thickness reduction in punching shear stress is noted, thus inversely proportional to each other.
