| Abstract: | Based upon engineering example the value of prestressing losses caused by friction between prestress without bond bar and wall of hole is measured and compared with theoretical calculation. The influences of prestressing losses of post tenstioned prestressing beam on the tension are analyzed. The research results have instruction functions for post tenstioned prestressing construction. |
