Abstract
If a sequence of the yielding of steel beam and the compressive failure of concrete slab can be controlled arbitrarily in verifying the bending moment resistance capacity of the steel-concrete composite beam, more rational proportion of the composite beam can be potentially designed using constitutive material performance. In this research, we attempt to clarify the influence of the arrangement of shear connectors, the yield strength of steel and the compressive strength of concrete on the load carrying behavior of the composite beam by using the RBSM analysis with nonlinear material properties. As a result, we clarify that the load carrying behavior of the composite beam is characterized at four load stages based on the damage of steel beam and concrete slab, and that those stages depend on the arrangement of shear connectors and the yield strength of steel.
