| Abstract: | Based on the tension data of 3 standard 37 # cap beam at Xibu Port,it analyzes the factors influencing the elongation value of steel strand.The result shows that there exists omission during calculation of theoretical elongation value.Combined with the characteristics of prestressed tension in bridge engineering,it puts forward an empirical formula and its application conditions for calculating the actual elongation value,which can provide reference for peers. |
