Composite beams are made of steel sections connected with slabs of concrete held together with shear connectors. The beams enhance the loading capacity and stiffness according to AISC and AASHTO design standards. In this study tests on three restrained steel-concrete full composite beams subjected to a cyclic point load and monotonic loading were conducted and their performances on stiffness, strength, ductility and energy dissipation capacity were analyzed and compared with the results of monotonic loading cases. It was found that the degree of the shear connectors and the type of loading and the position of the load were the major factors influencing the stiffness and cumulative energy dissipation capacity of the full composite restrained steel beams.

Composite structures are made from steel connected with slab concrete holding together with shear connectors. This facilitates in loading capacity according to AISC and AASHTO standard design. The test on restrained steel-concrete beams under monotonic loading and cyclic loading condition is with the fully composite and the partially composite. The result of this research is that the fully composite is more loading capacity than the partially composite. Moreover, the study also focuses on the deformation capacity ratio between the fully composite and the partially composite under both mentioned conditions. In this aspect, it is found that the deformation capacity of the fully composite is less than the partially composite. From the study, it is suggested that the steel-concrete composite be design for the fully composite because it can hold the highest strength, prevent slipping between steel and slab concrete, and increase the durability.
