PURPOSE: A floor plate structure including a steel-concrete composite beam to reduce the story height and a construction method for the same are provided to lighten the weight of a steel-concrete composite beam and facilitate the delivery and installment by pouring concrete to the steel-concrete composite beam in the field. CONSTITUTION: A steel-concrete composite beam to reduce the story height comprises a beam member(110), a strand(130), and a stiffener(150). The beam member comprises upper and lower flanges(111,112) and a web(113). A concrete part(230) is integrally poured on both sides of the web. The steel-concrete composite beam and column are joined. A deck plate(210) is installed on the upper surface of the lower flange. The upper surface of the deck plate is poured with concrete by being embedded with the strand. The strand is tensioned to introduce pre-stress and construction of a floor plate. |
