Calculating and analyze the compression bending strength according to the method of reinforced co ncrete structure design code and " the modified simple superposition method " , the distribution of axial load is obtained , then , the influence of creep is considered and the formulation of distribution of axial load between reinforced concrete and steel is proposed . and steel is proposed 運用現行混凝土結構設計規范和改進后的簡單疊加方法分別計算試件的壓彎承載力,通過對比分析,推得了src柱的軸力分配,然后在考慮了徐變系數的影響后,對空腹式鋼骨混凝土柱軸壓比限值提出建議。
