Elastic and Limit Analysis of R. C. Skew Slabs: Finite Strip Method

In this book an attempt is made to develop finite strip method for the elastic and limit analysis of reinforced concrete skew slabs, with various boundary conditions and loadings and to present the numerical and graphical results both elastic and limit in a way that they find immediate applications. The results are presented in the form of distribution coefficients for deflections and bending moments, for aspect ratios 1, 1.5, and 2. The effect of skew is investigated on behavior of skewed slab with various support conditions and subjected to various types of loads. The slabs having skew angles 0 degree to 60 degrees with increment of 15 degree are considered. The higher order finite strip technique is extended, to study the load deflection behavior of reinforced concrete skew slabs and to estimate the collapse load of slab. The Von-Mises yield criterion is used to develop yield pattern for square/rectangular and skew slabs. The proposed method predicts yield line pattern for reinforced concrete skew slabs, which is in reasonably good agreement with available experimental and analytical results. The plastic hinges formed, follows the yield line pattern.
