通过外粘型钢加固法和增大截面加固法的组合利用,有效解决了某三铰拱梁存在的正截面和斜截面承载力不足的问题,并通过设置拱间支撑,解决了结构位移超限的问题,对于目前混凝土异型构件的加固研究具有一定的参考价值。
Through the combined use of external sticky steel reinforcement method and enlarged section reinforcement method, the problem of insufficient bearing capacity of the normal section and oblique section of a three-joint arched beam is effectively solved, and the displacement of the structure is solved by setting the arch support. The problem has certain reference value for the reinforcement research of concrete shaped components.
