각형강관을 사용한 합성보의 기초적 연구 - 각형강관의 휨성능 ( The Basic Study on the Composite Beams Using Square Hollow Section Steel Members )

The square hollow section steel members which resist against torsion, local buckling and lateral torsional bucking are being broadly used for column members. They are used only for vierendeel truss and Delta beam in finland which is composite beam that precast slab is assembled as a trapezoidal square hollow section steel members. In this background, this study is the basic study to develop the composite beams using square hollow section steel members. To evaluate the bending capacity of square hollow section steel members, An experiment was conducted on H-shaped section beam using square hollow section steel beams with and without infilled concrete.
