Numerical Analysis of Two Way Slab With Openings

Abstract

Slabs are the concrete elements used as significant components in building. It is common to have openings in slabs for various operational reasons like electrical, mechanical and plumbing services as a result decreases their capacity to carry loads. Along with this, insufficient data is available for slabs having openings at centre and at eccentric positions to resist applied loads. Moreover, many difficulties were faced analytically while modelling the complex behaviour of RCC slabs in nonlinear zone. Therefore, they require special attention in both analysis and design. This research gives more attention on studying structural behaviour of two-way slab having openings at centre and at eccentric positions along with solid slab. To study this type of behaviour seven different models of square slabs having different shapes of openings like square, rectangular and circular at centre and eccentrically has been generated in ANSYS, which is a FEM based software. All specimens were subjected to load, which was increased from zero to failure load. The effects of opening shape on crack formation were also analysed.
