HYBRID BEAM HAVING UPPER FLANGE OF CONCRETE-FILLED TUBE

摘要

The present invention relates to a hybrid beam, wherein a concrete-filled tube comprises an upper flange. More specifically, concrete is filled in a compression side to prevent local buckling of a steel sheet, so that the hybrid beam can perform a stable behavior even if the hybrid beam has a long span. According to an appropriate embodiment of the present invention, the hybrid beam having an upper flange of a concrete-filled tube comprises: a lower flange having a steel sheet shape to be horizontally formed; the upper flange having a steel tube shape to be spaced toward an upper portion of the lower flange; a web enabling the lower flange and a center portion in the width direction of the upper flange to be vertically coupled; and concrete filled in the tube type upper flange.;COPYRIGHT KIPO 2016
