As construction technology have been developing, structure numbers which construct a building subjected to combined loading. not a loading that have been designed for the past tirres. This study evaluated effect that get on internal force of composite beam by various situation of construction. For example, there would be effect that change internal force of section by degree of shear connection and soil pressure action time. So we need a P-M interaction curve of composite beam section which can evaluate internal force. P-M interaction curve shows a ultimate limits of the internal force of structure numbers subjected to axial force and bending moment. Study for P-M interaction curve design is very important part to design structure numbers.
This study designed P-M interaction curve of composite beam that reflect asymmetry and examined internal force of composite beam through P-M interaction curve under various condition. As a result, we could know that P-M interaction curve was increased than existing P-M interaction curve when only axial force acts to steel materials. and proposed more accurate design method that reflects effect of bending strength by the degree of shear connection to existing P-M interaction curve.
