Abstract

   A decrease of pre-stress is greatly influenced the load carrying capacity immediately and leads to the decrease in safety in the pre-stressed concrete (PC) structure. It is necessary to know existing action stress accurately to maintain the PC structure . In this study, new existing action stress measurement technique was developed by the digital image correlation method and stress relief technique and the proving test of a developed method was done by using pre-tension concrete beam. Results, existing action stress was able to be measured in high accuracy.
