| Abstract: | When the strength of pre-tensioned pre-stressing component reaches its designed tension-release strength,the different prefabricating plants and different companies adopt different tension-release methods to release the pre-stress of the steel reinforcing bar.This article sums up several commonly used methods for releasing the tension,and makes a comparison among them for reference in future assembling of tension release facilities for the construction of a new pre-tensioned prefabrication yard. |
