摘要
方钢管膨胀混凝土是一种较为理想的钢管混凝土结构。在偏压试验的基础上,依据现有规程对方钢管膨胀混凝土偏压短柱构件承载力进行研究,并依据极限平衡理论,提出适合方钢管膨胀混凝土短柱偏压极限承载力的计算方法,供工程实践和相关理论研究参考。
Square expansive concrete-filled steel tubes （ECFT） are a sort of optimization design for concrete-filled steel tubes （CFT）. On the basis of test in eccentrically compressed square ECFT,the mechanics behavior of the member under eccentrically compressive load is studied in accordance with existing codes and specifications. The formula for the ultimate strength of eccentrically compressed square ECFT short columns is proposed by using the limit analysis theory, which can be a reference for the design and the theory study of square ECFT members.
