합성보 구조의 LRFD에 관한 연구 ( A Study on LRFD of Composite-Beam Structure )

This report is concerned with the development of Load and Resistance Factor Design Criteria of composite beams. Resistance Factor pie of LRFD Method could be obtained from statistical study of ultimate strength of composite beams under positive moment. Its values were: pie=0.081 in the case of solid slab, pie=0.871 in the case of deck slab. As the result, we could find out that pie=0.85 would be reasonable for serviceable safty.
