Abstract

The effect of temperature in the prediction of long-term loss of prestress, particularly on the re- laxation loss of prestressing strands, in prestressed concrete has been studied. The factors affecting the relaxa- tion loss in prestressing strands have been varied experimentally in Structural Engineering Laboratory at the Indian Institute of Technology Madras. The measured relaxation loss is compared with different experimental results and various codes.
