钢管混凝土的抗压模量和抗弯模量是不相同的，本文分析了含钢率、钢种、混凝土强度等级对钢管混凝土平面框架采用两种模量取值引起的计算结果的差别的影响，并分析了两种模量取值引起的双向荷载作用下的钢管混凝土框架顶端侧移和基底弯矩的差别。
The compressive modulus and flexural modulus of CFST are not the same. In this paper, the influence of steel grade, steel grade and concrete strength grade on the difference of calculation results caused by the two modal values of CFST plane frame is analyzed The differences between the top-side displacement and the base-moment of CFST frames under two-way load caused by the two modulus values are analyzed.
