T형 강재를 이용한 프리스트레스트 콘크리트 부분 매립형 합성보의 구조적 성능에 관한 연구

Abstract

The purpose of this study is to make the architectural hybrid system extend the limit of the market through simplification of joint and minimizing of works in situ. Tra-combined Prefab System consists of a half honeycomb`s T-shaped steel and pretensioned prestressed precast concrete. It has a repectitive section that consist of solid web section and open web section. As a result of test and anaysis, TPS composite beam has been concluded as follows. It was confirmed that equation of local buckling by T-shaped steel`s local stress contents with the result of test. Assumed deformation within the scope of elasticity was similar to measurements. it was confirmed that TPS composite beam keeps sufficient ductility after yielding point without rupture of shear or local bucking. Finally, we found that TPS composite beam has structural capacity as composite beam with H-beam. Especially, in case of long-span structure more than 15 meters, it is estimated more excellent than general composite beam with H-beam in reduction of story height, deflection, vibration for using, and cost.
