薄壁钢-混凝土组合结构研究现状

Research Status of Concrete-Filled Thin-Walled Steel Composite Structure

薄壁钢-混凝土组合结构,是由冷弯薄壁型钢或薄壁钢管和混凝土的组合构件形成的一种新型结构形式。它具有轻钢结构的优点,同时混凝土的存在改善了薄钢板的稳定性,增强了结构的防火性能,具有施工方便、工期短等优点,适用于中、低层房屋。

Concrete-filled thin-walled steel structure is a new type of structure, which is composed of cold-formed thin-walled steel elements or thin-walled steel tubes with concrete. It has advantages of light-weight steel structure which is also improved its stability and fire-proof character by concrete. The construction of this structure is convenience and the construction period is short. It can be applied in multi-story and lower-story buildings.
