Punching Shear Study on Composite RC Flat Slab Using Finite Element Method

Abstract

In recent decades, there was a significant improvement in utilization of RC composite structural elements as a building member. In particular, the usage of composite steel section at the joint regions of structural members are getting developed. The composite RC structural elements show a noticeable performance in higher structural strength with reduced member size, stability and effectiveness makes the attractiveness in construction field. The present study will primarily aim to provide a suggestion in usage of composite steel section in the application of punching shear resistance in composite RC flat slabs. In this regard, an experimental investigation is going to be done to study the punching shear characteristics of composite RC flat slab. To compare the results obtained from experimental investigation, an analytical investigation is also going to be stimulated using finite element analysis software “ANSYS”. The basic properties of composite steel and reinforcement were done experimentally to model the material properties in “ANSYS” software. The parameter considered in this study is the embedding the additional composite steel member with different sections and shape at the punching failure zone to resist the punching shear force. The punching shear performance in terms of load carrying characteristics, failure modes are going to be examining experimentally and analytically.
