A Simplified Method for Designing RC Slabs under Concentrated Loading

Abstract

Designing two-way slabs under transverse concentrated loads is one of the challenges in designing such structures. No certain method can be found in the design codes or references for designing two-way slabs subjected to concentrated loads. However, plastic method can be the best method for designing such cases of two-way slabs. This method requires various formulas for different conditions of RC slab and so, is practically not simple and not usable in designing offices. In this paper, plastic method is used for different conditions of RC slabs and also various dimensions, in order to derive the essential formulas followed by calculating the positive and negative moment coefficients for concentrated loading located in different points of a two-way slab. The efficiency of this method is shown by a numeric example at the end of the paper.
