PURPOSE: A prestressed composite beam with a slit-typed web is provided to improve composite effects with concrete and to obtain high bending rigidity and excellent torsional strength. CONSTITUTION: A prestressed composite beam (1) with a slit-typed web comprises an upper flange member (100), a lower flange member (200), a slit-typed steel web (300), and a concrete part (400). The slit-typed steel web is entirely connected to the upper and lower flange member. The slit-typed steel web comprises slits (310) at a regular gap. A slit comprises linear slits (311) in the center and diagonal slits (312) at both sides. The concrete part is only embedded with the slit-typed steel web or is entirely embedded with the upper and lower flange member and the slit-typed steel web. |
