摘要 列举了国外现有的各种FRP筋锚具的特点和失效模式,对FRP筋锚固系统的技术要求进行总结归纳,介绍了减小锚固区应力峰值的两种方法:软化区概念和角度差异概念和在此基础上设计的新型锚具。 The performances and the failure mode of current available anchors for FRP tendon at abroad are presents. The technical requirements of anchorage system for FRP tendon are summarized. Two concepts are presented to reduce stress peak in anchorage zone： the soft zone concept and the differential angle concept and new designed anchors based on these concepts are given.
