Low retracting pre-stressing anchorage system(LRPAS) is a new type of post-tensioned prestressing system.An experimental study was carried out to investigate the structural behavior under the new LRPAS.A scaled test specimen using low retracting pre-stress stranded single anchorage was constructed and tested.Based on the strain measurements,the stress field under the traditional anchorage and the new LRPAS were obtained,and the test results were consistent with the theoretical calculation ones.When the same...
