钢筋混凝土柱外包粘钢加固技术试验与应用

Testing and Application on Strengthening Technique of R.C. Column Wrapped and Bonded by Steel

本文通过钢筋混凝土短柱的外包粘钢加固的试验,将包钢与粘钢方法结合起来,加固后的外包粘钢与原混凝土之间能共同工作,并在原混凝土内形成三向应力状态,大大提高了结构整体承载力,并且空间占用较小,现场加固工艺简便,工期短,对周围环境影响小。在广东省电力一局万益钢结构厂主厂房钢筋混凝土柱加固的实际工程应用中,保证了工厂能够按期完成钢结构生产任务,取得了良好的经济效益与社会效益。

For R.C.short column wrapped and bonded by steel,a study is made to check the performance, and the result shows that the R.C.column and the steel can work together and form a planar stress in R.C., this technique increases the bearing capacity of R.C.greatly,reduces the space occupied,is operated simply,and has few effect on environment.Theadvantage of this art has been proved in the practical engineering of WanYi Steel Structure Plant of GEFB.
