Study the Behavior of C-shaped Column and at Plate Slab Structural System for Punching Shear Under Gravity Loads

Abstract

In India, Post-tensioning is the most versatile form of prestressing in buildings, a technique which enables engineers to make the most e ective use of the material properties of concrete and so to design structural elements which are strong, slender and e cient. Design in post-tensioned concrete is not di cult and if done properly can contribute signi cantly to the economy and the aesthetic qualities of a building. In present study at slab and c-shaped column structural system has been studied for the e ect of the punching shear due to gravity loads and the guidelines of various codes has been studied and compared to add to the supplementary information to the Indian codal context. The Punching shear is the ultimate failure in the at slabs and since the use of post tensioning in the at plate slabs is extensive and quite appreciated by the users. The present study also contains analytical work for the reinforced concrete and post tensioned at plate slab and c-shaped column connection, along with the experimental investigation of the reinforced concrete at plate slab to check the ultimate punching shear failure. The C-shaped columns are rarely used in current practice but it may be useful in the future and the critical section of the shear for the C-shaped column and the at plate slabs with the opening in side the critical section has not been speci ed in any of the guidelines across the world, hence in this project the e orts are made to evaluate the critical section and the punching shear behavior of the C-shaped column and the at plate slab structural system under gravity loads.
