Abstract EN
In the design of prestressing concrete structures, the friction characteristics between strands and channels have an important influence on the distribution of prestressing force, which can be considered comprehensively by curvature and swing friction coefficients.
However, the proposed friction coefficient varies widely and may lead to an inaccurate prestress estimation.
In this study, four full-scale field specimens were established to measure the friction loss of prestressing tendons with electromagnetic sensors and anchor cable dynamometers to evaluate the friction coefficient.
The least square method and Bayesian quantile regression method were adopted to calculate the friction coefficient, and the results were compared with that in the specifications.
Field test results showed that Bayesian quantile regression method was more effective and significant in the estimation of the friction coefficient.
