ANALYSIS OF SIMPLY SUPPORTED REINFORCED CONCRETE SKEW SLABS

Reinforced concrete skew slabs are widely used in bridge construction when the roads cross the water streams and canals at angles other than 90 degrees. They are also used in floor systems of reinforced concrete buildings as well as load bearing buildings where the floors and roofs are skewed for architectural reasons or space limitations. In the present work, the load-deflection behaviour of simply supported reinforced concrete skew slabs was analysed using experimental and analytical methods. Finite element modelling of eighteen numbers of simply supported reinforced concrete skew slabs were made and non-linear analysis carried out on all skew slabs to obtain the load-deflection relationship under the action of uniformly distributed load. To carry out this analysis, a commercial Finite Element (FE) software ANSYS version 15 was used. Also, a method is proposed to predict the theoretical loaddeflection curves. A comparison has been made between the experimental load deflection curves and using theoretical method, with the results of ANSYS.
