型钢-混凝土组合梁在改造加固中的理论研究

Theoretical Research on the Application of Shaped Steel-Concrete Composite Beams to Transformation and Repair

本文对梁底采用型钢加固的混凝土组合梁的抗弯性能进行了理论分析 ,并与用加大截面法进行加固的梁进行了比较 ,提出了采用型钢加固梁的实用计算公式 。

In this paper, the bending capacity of beams strengthened by adding shaped steels to the bottom of the beams was studied, and was compared with the beam of increasing the sections of the beams. The practical formulas were put forward to afford the experimental and theoretical basis for real projects where this composite beam strengthening method can be used in the future.
