Experimental Investigation of Prestress Losses in Full-Scale Bridge Girders
The discussed paper presents an interesting experimental study on prestress losses in full-scale, precast, pretensioned bridge girders. Several specimens were fabricated, conditioned, and tested to enable comprehensive assessment of short- and long-term prestress losses, including the effect of various parameters on the development of prestress loss, the evaluation of various methods for monitoring and measuring prestress loss, and the performance of various prestress loss estimation procedures. The authors should be complimented for producing a detailed paper with comprehensive information. This is acknowledged by the discusser, who would like to offer the following comments and questions for their consideration and response -- mainly about some aspects included in the "Experimental Results and Discussion" section and the corresponding conclusions. The authors conclude that concrete stiffness was found to be strongly dependent on the coarse aggregate type and content, which in turn greatly affected the magnitude and development rate of prestress loss
