Abstract
The ultimate moment of resistance of the composite beam with the steel beam and the reinforced concrete slab generally depends on the classification of the cross sections. JSCE Standard Specifications for Hybrid Structures also use the classification of the compact, non-compact and slender cross sections to calculate the ultimate moment of resistance of the composite beam. However if we can calculate the ultimate moment of resistance of the composite beam regardless of the classification of the cross section, more rational proportion of the composite beam can be potentially designed using constitutive material performance as possible as we can.
In this research, we conduct the static test of the composite beam specimens which is the beam with the compact cross section and we attempt to confirm the load carrying behavior of the specimen in detail. In this case, two types of the specimens with studs differently arranged at equal intervals are employed and we investigate especially the sequence of the damage of the steel beam and the concrete slab such as the yielding of steel and the compressive failure of concrete.
