PURPOSE: A composite beam structure is provided to simplify assembly and reduce installation periods as a bolt can be assembled only with man power in the assembly of a U-shaped steel frame bracket and a U-shaped precast concrete (PC) member. CONSTITUTION: A composite beam structure comprises a U-shaped PC member (15) including two webs and a cast-in-place slab. Cast-in-place concrete is filled in a composite beam. A shear resisting plate (60) is extended and forms a connection end (77). The connection end forms a connection unit by being hung on the end of a steel frame bracket. A part of the shear resisting plate connected to the connection end comprises a vertical plate and a horizontal plate. A part connected to the U-shaped PC member comprises a vertical plate and a connection member. |
