Abstract
To design reinforced concrete beams, engineers all over India refer to IS 456-2000. Nowadays finite element software is used for any design rather than hand calculations. In the appendix of the latest revised code for bridges IRC 112-2011, design procedures using three-layer sandwich model based on finite element analysis has been included for the design of reinforced concrete structures. In the sandwich model, a shell element is divided into three layers. The top and bottom layer are supposed to take out of plane moments and the core carries out of plane shear. In this paper, sandwich model has been used for the design of reinforced concrete beams. Here solid and hollow rectangular beams are considered for the design. The results are then compared with IS 456-2000.
