采用部分区段粘贴FRP方法加固混凝土梁

用FRP加固混凝土桥梁的方法已很普及,但它会导致结构延性下降,即超脆性破坏,分析和试验证明,将全长粘贴FRP改为只粘贴两端而中部不粘贴的部分区段粘贴法,可以改善被加固结构的延性。

Reinforcing Concrete Beams with Partial Sticking FRP

Reinforcing concrete beams with FRP are commonly seen,but this method may cause poor structural ductility(brittle damage).The analysis and experiments show that sticking FRP on the ends of the beams instead of sticking the whole beams can improve the ductility of the reinforced structure.
