【摘要】 FRP筋具有优异的耐腐蚀性能,是替代普通钢筋和预应力钢筋用于腐蚀环境和特殊工程的最佳选择之一。同时,FRP筋又具有抗拉强度高、疲劳性能优、徐变松弛性能好等优良力学性能。本文在系统地查阅国内外代表性研究文献的基础上,对FRP筋的长期力学性能进行了研究和总结。更多还原

【Abstract】 Because of excellent corrosive resistance,FRP has been taken as an attractive alternative reinforcing material for steel to the corrosion problem. At the same time,FRP provides a high strength,good fatigue properties,low relaxation and creep rates,etc. Based on extensive reading of references at home and abroad,this paper describes the newest research work on the long-term mechanical properties of FRP tendons.更多还原
