Disclosed is a long span composite beam. According to an embodiment of the present invention, the long span composite beam includes: asymmetric H-steel having a lower flange, an upper flange having a greater width than that of the lower flange, and a web connecting the lower flange and the upper flange; a rib steel plate which is curved in a trapezoidal shape in which a width of a lower portion is greater than that of an upper portion, in which opened cross sections of both lower ends are bonded to an upper end of the upper flange so that a closed cross section is formed, and which is arranged in a predetermined distance separated from the end of the upper flange; and a plurality of support reinforcing bars arranged on an upper portion of the upper flange between the end of the upper flange and the rib steel plate. Therefore, the long span composite beam has improved structural performance and efficiency.
장스팬 합성보가 개시된다. 본 발명의 실시 예에 따른 장스팬 합성보는 하부플랜지와 이보다 폭이 큰 상부플랜지 및 하부플랜지와 상부플랜지를 연결하는 웨브를 가진 비대칭 형상의 H형강; 하부가 상부보다 폭이 큰 사다리꼴 형상으로 절곡되며, 양쪽 하단의 개방된 단면이 상부플랜지 상단에 접합되어 폐단면을 형성하되, 상부플랜지의 끝단으로부터 설정된 이격 거리에 배치된 리브강판; 및 상부플랜지 끝단과 리브강판 사이의 상부플랜지의 상부에 배치된 복수의 지지철근;을 포함한다.
