Evaluation of Elastic Deflections and Bending Moments for Orthotropically Reinforced Concrete Rectangular slabs Supported on Three Edges Only

Abstract

This paper deals with the evaluation of the elastic deflections and bending momentsfor orthotropically reinforced concrete rectangular slabs supported on three variouslyrestrained edges with the fourth edge free and subjected to uniformly distributed load.Six cases are considered for such slabs to cover all possible restraining conditions at thethree supported edges. Based on the finite difference approach, equations are derived tocalculate the maximum values of the positive and negative bending moments as well asthe maximum deflection in any of these six slab cases caused by the applied uniformload.
