摘　　要：钢管混凝土叠合柱具有抗震性能好、断面小、防火防腐性能好等众多优点,但是在目前的结构设计软件中很难真正模拟,相关规范也只给出了简化计算方法,并且计算过程仍非常繁琐。从材料本构关系出发,提出了基于平截面假定的叠合柱正截面受压承载力计算方法,并进行编程计算,计算结果表明此计算方法很好地反映了叠合柱分阶段受力的特点。此计算方法已在一些项目的设计中得到运用,效果较好。Steel tube-reinforced concrete column has many advantages such as good seismic performance, small section, good fire and corrosion resistance, but it is difficult to simulate in the current structural design software. The relevant specifications only give a simplified calculation method, and the calculation process is still very cumbersome. Based on the constitutive relation of materials, the calculation method of the compressive bearing capacity of the steel tube-reinforced concrete column based on the assumption of plane section was proposed and programming calculation was carried out. The calculation results reflect the force characteristics in different stages of the columns well. This calculation method has been applied in the design of some projects and has a good effect.
