摘要
本文结合工程实践，通过十二层框架结构开展了正截面抗压、斜截面抗剪加固补强以及加固方案对比研究和分析计算，对砼结构加固原理和加固方法进行了探讨，以求提供行之有效的加固方法和设计计算理论。
This paper, through the engineering practice of a 12 - storey frame structure,makes a contrastive study and an analysis calcuation of the compression strength of normal section, the shear strength of oblique and the strengthening schemes. The principles and methods of concrete structure stiffening is discussed to provide feasible and effective strengthening methods and design theories.
