| 摘 要： | 在预应力撑杆加固普通钢筋混凝土柱极限承载能力基本计算公式的基础上，讨论了加固柱的弯矩M和轴力N的关系，获得了M-N关系曲线，将其与未加固柱的M-N关系曲线进行比较，结果表明，对普通钢筋混凝土柱进行预应力撑杆加固有一定适用范围．

| Abstract: | Based on the basic formula of the limit load-bearing capacity of reinforced con crete (RC) columns strengthened with prestressed struts, the relationship betwee n moment M and axial load N of a strengthened column is analyzed theoret ically, and its M-N diagram is obtained. By comparing with the M-N dia gram of a common RC column, the result shows that this strengthed method has a r easonal range of application. |
