1) bonded FRP tendon
有粘结预应力FRP筋
1.
So the deflections of concrete beams prestressed with bonded FRP tendons are expected to be larger than those of the steel bars cases.
与预应力钢筋相比,FRP筋的弹性模量较低、粘结性能稍差,因此有粘结预应力FRP筋混凝土梁的挠度比相应的预应力钢筋混凝土梁的大。
2.
The failure modes of concrete beams prestressed with bonded FRP tendons can be classified into three types: the balanced failure,compression-controlled failure and tension-controlled failure.
国内外已有试验研究表明,有粘结预应力FRP筋混凝土梁的破坏模式包括界限破坏、受压破坏与受拉破坏三种。
3) prestressed FRP bar
预应力FRP筋
1.
A research summarize about prestressed FRP bar concrete beam sliffness;
预应力FRP筋混凝土梁刚度研究综述
2.
The relative slip will unavoidably come to pass on the bar-concrete interface in a prestressed FRP bar-concrete composite beam under external loading,and the stress in a prestressed FRP bar increases correspondingly with the external loading.
外荷载作用下,预应力FRP筋钢与混凝土组合梁的交接面必产生相对滑移,预应力FRP筋内力会随外荷载增加而增加,这种交接面滑移和FRP筋内力增量会导致混凝土翼缘板、钢梁、连接件受力性能发生变化。
4) bonded nonprestressed tendons
有粘结非预应力筋
5) unbonded tendons
无粘结预应力筋
1.
Effects of corrosion of the unbonded tendons on the mechanical behavior of the tendons and bearing capability of the structure are discussed.
无粘结预应力混凝土结构的耐久性问题是无粘结预应力结构使用的关键问题,但是目前对无粘结预应力筋的防腐蚀研究还不完善,有待于深入和发展。
2.
The embedment of unbonded tendons,the calculation of elongation value,the key points in construction of swimming anchor angle tension and so on are introduced,providing a reference for relevant construction.
详细介绍了无粘结预应力筋的预埋方法、伸长值的计算方法以及游动锚变角张拉的施工要点等,为相关施工提供了参考。
6) retard-bonded prestressed tendons
缓粘结预应力筋
