Abstract
This paper presents an experimental investigation on the effect of the thickness of steel sheets in steel
encased concrete structures. This experiment includes two steel encased concrete beams of size 0.3 x 0.3 x 1.2 m
with a thickness of 4mm and 2mm steel sheets. They are designed for a shear failure at 50kN without any
compression and tension reinforcement which are tested under two point loading on 100 tones loading frame till
their failure. Failure of encased beams is primarily due to bond slip failure between steel and concrete, which
leads to the yielding of steel where failure occurs. In this study both beams failed at the interface at a similar
load, where beam-2 failed at more strength when compared to beam-1.
