The invention discloses a steel-concrete composite beam adopting a corrugated steel web, which relates to a corrugated steel web composite beam capable of being applicable to highway bridges and railway bridges. The beam comprises a top flange concrete composite plate, a corrugated steel web plate, a top flange steel plate, a box beam bottom plate and male pin connecting pieces, wherein the top flange comprises a precast concrete slab and a cast-in-place concrete layer; and the top flange concrete composite plate is connected with the top flange steel plate into a whole through the male pin connecting pieces welded on the top flange steel plate. By adopting the structure, the problems that the site workload and the construction difficulty for casting a bottom flange concrete slab of a traditional corrugated steel web composite beam are large, the construction quality is difficult to guarantee and the like are overcome on the premise that the quantity of steel is hardly increased, meanwhile, the tensile property of the steel plate is fully played, the bearing capacity, the rigidity and the cracking resistance of the structure are improved, and the durability of the structure is improved, therefore, the corrugated steel web composite beam has the advantages of simple structure, reasonable stress, quick and convenient construction, and good technical and economic benefits.
