摘　　要：为寻求一种较为简单的方法，计算钢骨混凝土柱的正截面强度，对钢筋混凝土部分和钢骨部分所承担的轴力大小进行了分析，根据冶金工业总公司结构设计标准中的正截面承载力计算公式，提出了一种新的轴向力分配方法，该方法根据钢骨混凝土柱在轴心受力状态下，钢骨部分与钢筋混凝土所处的状态来分配轴向荷载，然后根据现有规范来计算两部分的承载力，其和即为钢骨混凝土柱的正截面强度。该方法使得钢骨混凝土柱正截面承载力计算方法概念明确，计算简单。To look for a simple method of calculating the bearing capacity, how to distribute the axial force was analyzed. According to the formula of the bearing capacity of steel reinforced concrete columns which are in design code. (Steel Reinforced Concrete Structure Design Code), a new method to determine the distribution of the axial force between the reinforced concrete part and steel part was proposed .The new method is that axial force can be allocated easily between the two parts when the columns is only in axial force state, the bearing capacity of the two parts can be got respectively from code formula. The bearing capacity of column is the addition of the two parts. The new method is simple and agrees well with the test results.
