prestressed with bonded tendons 有粘结预应力
bonded prestressed tendons 有粘结预应力筋
bonded nonprestressed tendons 有粘结非预应力筋
The study was both experimental and analytical. 22 partially prestressed concrete beams with unbonded tendons and 4 with bonded tendons were tested.
试验研究了22根无粘结和4根有粘结部分预应力梁在三分点荷载作用下的抗弯性能。
The structure and construction method of externally prestressed structures differ greatly from structures with bonded or unbonded tendons, therefore generate the difference in prestressing loss.
体外预应力结构的构造形式及施工方法与有粘结或无粘结预应力结构有较大差别，因此，其产生的预应力损失也不同。
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。
