Steel-Concrete-Steel sandwich structures are made of concrete core sandwiched in between two steel plates, has been usedin port and harbour facilities, submerged tube tunnels, protective structures, building cores, etc. in which resistance against impact and sudden loads is an importance aspect. Objective: To investigate the behaviour of the sandwich beam under flexural loading. The shear connectors varied in the sandwich beam are L-Angle, Channel, Tee section and Headed bolt. The load-deflection, load-strain and load-slip behaviour was plotted and compared with different shear connectors of the sandwich beam. Methods/Analysis: All the sandwich beams were also analysed using finite element software ANSYS. From the study it was concluded that sandwich beam with channel and Tee connectors performed better than the beam with angle and headed stud connectors. Findings: From the load slip behaviour, the stiffness of the different connectors was found. The load carrying capacity of the sandwich beam with Tee and Channel connectors were improved by 70 % compared to angle and headed stud connectors. The maximum deflection found from the analytical models was lesser than the experimental results. The analytical model is found to be stiffer due to rigid connections of the model. Application: The load-strain, load-deflection and load-slip behaviour was also studied. The analytical study was also carried out using ANSYS to compare the results. The conclusion arrived from the study are.
