SC보와 RC보의 휨내력에 관한 연구

The merits of composition structure are used efficiently for building of high-rise. long span and massive. Currently, the research of CFT (Concrete Filled steel square Tube) used steel square tube have located high level. But. the research about steel square tube beams and SC beams that used steel square tube which have variety merits about. structural torsion, local burkling and lateral burkling are lock. In accordance, the purpose of this study are furnishing basic data about steel square tube beams and SC beams for efficiently researching about SC beams. throughout comparison flexural strength of RC beam which has same sectional dimension.
