摘　　要：根据弹性稳定理论,对当量弯矩折减系数Cm的计算公式的应用范围作了进一步说明,并确定了其应用范围。同时,考虑砼偏心受压构件的弹塑性性能,推导了新的公式,与原有的公式比较,具有同样的精确度,由于考虑了砼材料的变形模量,因此其结果更接近实际。In accordance with elastic stability theory, this paper makes a further explanation about tile range of application of the computational formula of equivalent bending moment factor Cm, and defines its range of application. Considering the elastic plasticity capability of eccentric compression component of concrete, a new formula is deduced, which has the same accuracy compared with intrinsic formula. Since the deformation modulus of the material, the result is much more practical.
