摘要
介绍了体外预应力转向块的构造形式,并模拟体外受弯构件的工作状况,研究了转向块对体外预应力筋偏心距二次效应的作用及转向块对体外预应力结构承载能力的影响,为体外预应力技术在工程中的应用提供了参考.
This thesis conducted a research on the structure form of external pre-stressing deviators, on the second-order effects produced by deviators reducing the external pre-stressing tendon, on the effects of structure carrying capacity by deviators, and on the configuring principle of reinforcing steel bars. The results provide some reference to the application of external pre-stressing techniques to engineering.
