Analytical Studies on Bi- Steel Light Weight Concrete Sandwich Beam

S. Kuldeep and M. Bhuvaneshwari

This paper deals with study of static behavior of Bi-steel lightweight concrete beam (SLCS) which was simulated using a finite element model in Abaqus v6.1. During the course of analysis the lightweight concrete beam and SLCS beam, deflection and tension plate slip was observed. Due to the ductile nature and enhanced stiffness of the SLCS beam, the deflection of SLCS beam reduced by 43% from control beam. The slip of the SLCS beam was evaluated from the Contact open (C-Open) analysis. The variation between the load and C-Open was linear with negligible slip. Also very less Von Misses stresses was seen in the compression zone of the beam which gave good bonding of the shear connectors in the tension zone resulting in resistance to C-Open.
