STEEL-CONCRETE SANDWITCH TYPE HYBRID BEAM AND HIGH STRENGH HYBRID STRUCTURE SYSTEM USING THE SAME

摘要

Disclosed herein are a steel-concrete sandwich-type hybrid beam and a high strength hybrid structure system using the same. A shape steel member is arranged in pairs in both sides of the beam and a concrete is filled between the pair of shape steel members, and thus a high rigidity and high damping performance of RC frame and a construction efficiency of steel framing can be achieved simultaneously. Therefore, a convenience of construction and a good improved structural rationality can be obtained, thus reducing the construction cost, as compared with the conventional RC and PC beams having the same rigidity. The steel-concrete sandwich-type hybrid beam is formed of a steel member and a concrete member. A pair of lateral shape steel member forming both side faces of the hybrid beam is provided. A filled concrete is placed and cured between the pair of lateral shape steel members. The lateral shape steel members are disposed in parallel at regular intervals along the longitudinal direction of the hybrid beam.
