Analysis of infilled beams using method of initial functions and comparison with FEM

This paper presents a study carried out on reinforced concrete infilled beams. In reinforced concrete beams, less stressed concrete near neutral axis can be replaced by some light weight material like bricks to reduce the weight of the structure and also achieve the economy. Infilled zone is obtained with the help of stress block diagram, used for limit state design of reinforced concrete beams as per IS 456. Method of initial functions is used for the analysis of infilled reinforced concrete composite beams. The method of initial function (MIF) is an analytical method of elasticity theory. The results obtained by MIF are compared with those predicting by Finite Element Method (FEM) based software ANSYS, and it is observed that they are comparable.
