摘要
对具有不同边界约束条件的预应力加固受弯构件的作用机理进行了较为深入的分析与总结 ,提出了统一的加固计算方法及加固效能的判断准则 .
The mechanism of the reinforced concrete members strengthened by the external prestressed tendons with different boundary condition is investigated, and the influence of the boundary condition with a certain stiffness on the effective prestress values of the strengthened members is analyzed. A unified calculation formula is proposed for appraising the actual effective of the prestress.
