| Abstract: | As Prestressing strand wire elongation deviation is an important indicator to determine the reach of design control tension,the accurate computation of theoretical elongation and accurate measurement and calculation of the actual elongation has become very critical for the accuracy of the elongation deviation.Therefore,in this paper,the accurate computation method for the theoretical elongation,the measurement and calculation method for the actual elongation have been comprehensively introduced,which can be used as reference for engineers. |
