PURPOSE: A composite structure of concrete and a corrugated steel pipe of a corrugated steel web prestressed concrete composite girder using a penetrating L-section steel is provided to obtain a stable connection force with concrete by integrally connecting a concrete structure and the corrugated steel web. CONSTITUTION: A composite structure of concrete and a corrugated steel pipe of a corrugated steel web prestressed concrete composite girder using a penetrating L-section steel(20) comprises a corrugated steel web(10) and upper and lower concrete(30,40) combined in the upper end and the lower end of the corrugated steel web. The L-section steel is symmetrically connected to the upper end and the lower end of the corrugated steel web and is individually embedded in the upper concrete and the lower concrete. A plurality of shear connection holes(21) is formed on one side of the L-section steel. A shear fixing reinforcing bar vertically penetrates the shear connection holes and is combined with the concrete. |
