Experimental behaviour on study of sandwich beams

The Objective of the sandwich beams are used to reduce the self-weight, deflection and shear which being the major concern in case of conventional reinforced concrete beams subjected to loading. In this project work ,sandwich beams that are cast by the inclusion of thermo-col and weld mesh in the place of steel re-bars that are used in reinforced concrete beams has been the subject of several studies devoted to determine the influence of the main parameters. Due to the small value of span-depth ratio, the strength of beams are usually controlled by shear ,the yield strength and ultimate capacity of sandwich beams subjected to bending is to be determined through experimental methods. The experimental works are conducted to understand the various modes of failure that could occur due to the possible combination of shear and bending moment acting at a given section of a sandwich beams. Apart from highlights the experimental set-up, typical crack patterns, failure modes and load deflection behavior to be reported.
