［提要］為滿足大跨度建筑的樓層凈高的要求，控制樓板水平受力構(gòu)件的高度，提高樓板承載能力，提出一種新型的樓板結(jié)構(gòu)——鋼管空心混凝土板。將鋼管、鋼箱梁、鋼管柱組成的鋼框架結(jié)構(gòu)與樓板混凝土有效地結(jié)合在一起，整體受力，從而減輕樓蓋重量、減小截面尺寸、提高樓蓋結(jié)構(gòu)的承載能力。

New Type Reinforced Concrete Slab Cored with Steel Tube/Ou Yanjun1,2，Chen Xing1,Li Xin1(1 The Architectural Design and Research Institute of Guangdong Province, Guangzhou 510010,China; 2 Sun Yatsen University, Guangzhou 510275,China)
Abstract: In order to meet the net height requirement of the long-span building, a new slab—steel tube hollow concrete slab is proposed. Consisted of welded steel tube, steel box beam and steel tube column, the steel frame and the concrete slab are combined to reduce the selfweight of floor system and the size of section, and also improve the slab bearing capacity.
