摘　　要：钢管混凝土具有诸多优点,使其得到广泛的应用和研究。但也有缺点,如钢材的耐腐蚀性差,导致其后期维护费用较大。由于高强钢可以有效地减小构件的尺寸和结构的重量,不锈钢具有良好的耐腐蚀性能,铝合金具有外表美观、防腐蚀等优点,因此在上述3种金属管中填充混凝土形成新型金属管混凝土结构,具有广泛的应用前景。主要研究了3种金属管混凝土短柱的强度计算公式,并通过有限元模拟验证了公式的正确性。CFST structures, have been studied and used widely. However, there exists some disadvantages such as susceptible to corrosion, which will add the maintenance cost. Since the high-strength steel （HSS） could reduce the cross section area and self weight, stainless steel has the good property of corrosion resisting, aluminum alloy has the good virtues of lightweight, good looking and anti-corrosion, if we can pour concrete into these three types of metal tubes and form the new-type CFMT members, they should have potential development. This paper basically investigates the strength calculation formula of all three CFMT short columns and verifies its correctness with the simulating results of FEM.
