［提要］为满足大跨度建筑的楼层净高的要求，控制楼板水平受力构件的高度，提高楼板承载能力，提出一种新型的楼板结构——钢管空心混凝土板。将钢管、钢箱梁、钢管柱组成的钢框架结构与楼板混凝土有效地结合在一起，整体受力，从而减轻楼盖重量、减小截面尺寸、提高楼盖结构的承载能力。

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.
