As prestressing tendons, the stress relaxation property of FRP tendons must be studied.
将FRP筋作为预应力筋使用，必须了解其应力松弛特性。
So the deflections of concrete beams prestressed with bonded FRP tendons are expected to be larger than those of the steel bars cases.
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。
This paper introduces how to calculate the ultimate strength of external pre-stressed concrete beam with FRP tendons by means of strain reduction.
