Estimation method for prestress loss of externally prestressed composite girder bridges Yongming Zhao1, a , Hongxue Li2, b and Xuewei Wang3,c 1School of Civil Engineering, Southwest Jiaotong University, Chengdu, Sichuan 610031, China 2School of Civil Engineering, Southwest Jiaotong University, Chengdu, Sichuan 610031, China 3School of Civil Engineering, Southwest Jiaotong University, Chengdu, Sichuan 610031, China ayongming_zhao@126.com, bhongxuelee@163.com, cwxw5778@163.com Keywords: Estimation method, Prestress loss, External prestress, Composite girder bridge.
How to accurately calculate the value of the prestressing loss is an issue of great concern to engineers.
A large number of engineering practice shows that using external prestressing technology is to solve the above problem is ideal and effective method.
Conclusions With the wide application of external prestressing technology, in this paper, the estimation method for prestress loss of externally prestressed composite girder bridges is studied, the formula is derived to provide a reference for the engineering design.
