Abrégé

A composite beam according to the present invention has a low weight such that the composite beam may be easily lifted. Therefore, the constructability thereof is superior and transport fees thereof or the like are reduced. In addition, concrete consumption is small such that the composite beam is environmentally-friendly and may be easily coupled with columns.

Abrégé

A steel composite beam is manufactured by T-shaped steel, inverse T-shaped steels installed at opposite ends of the T-shaped steel, and vertical stiffeners installed on the inverse T-shaped steels. A method for manufacturing a composite beam using T-shaped steel and a method of constructing a structure using the same are capable of using less steel and minimizing dead weight of the composite beam compared to a steel composite beam having the same cross section and depth, and designing a cross section of the composite beam in an efficient and economical manner due to the pre-stress caused by tendons, providing easy connection with column members on the basis of length, providing efficient construction, easy management, and convenient construction for ceilings and finishing equipment due to light dead weight.

Abrégé

The present invention relates to a composite steel beam manufactured by T-type steel, to inverse T-type steel installed at both ends of the T-type steel, and to a vertical stiffener installed at the inverse T-type steel. The present invention relates to a method for manufacturing a composite beam using T-type steel and to a method for constructing a structure using same, which can reduce the consumption of steel and minimize the weight of the beam as compared to a steel composite beam having the same cross-section and depth, and which can be used to design the cross-section of a composite beam in an efficient and economically advantageous manner by employing a prestressed tendon, and which enables the easy connection of pillars, and which is relatively lightweight to enable efficient construction, easy management, and the convenient construction of a ceiling and finishing facilities. Further, the present invention has a pair of angle stiffeners opposite one another at the lower end of the middle part of T-type steel to form a lower tension flange and prevent a cut portion of a honeycomb-structured beam from being bent, thus reducing the number of PC cross-sections and tendons, increase an allowable compressive stress, supplement the compression transfer surface of the honeycomb part to reduce the possibility of lamellar tearing, ensure a vertical integrity with PC cross-sections as well as safety, and accomplish a stress transfer in the transverse direction to achieve structural stability.
