预应力撑杆加固柱弯矩与轴力的关系

Relationship between Moment and Axial Load of Reinforced Concrete Columns Strengthened with Prestressed Struts

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 concrete (RC) columns strengthened with prestressed struts, the relationship between momentMand axial loadN of a strengthened column is analyzed theoretically, and itsM-Ndiagram is obtained. By comparing with theM-Ndiagram of a common RC column, the result shows that this strengthed method has a reasonal range of application.
