【Abstract】 In this paper, experimental research was carried out on a kind of continuous composite steel-concrete beam whose flange is a concrete combined slab, formed by placing a layer of post-placedconcrete on a precast concrete slab. The behaviour of bending moment redistribution and the failuremode for these composite beams are pointed out. The calculating methods for the ultimatic flexuralstrength of support section and mid-span section are recommended. The serviceability limit state forthis kind of beam are also discussed, and a maximum factor of moment adjustment for the support mo-ment is given out.更多还原
