Measurements of Shrinkage Strain and Stress of an Existing Reinforced Concrete Structure in Japan

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

In this study, authors measured strain and temperature of existing reinforced concrete structure using embedded strain gauge for the purpose to predict the shrinkage crack risk of the concrete structure. Authors also measured shrinkage and restrained of stresses relationship of concrete at laboratory. As a result, the shrinkage of the concrete under actual environmental condition was approximately 300∗10-6 at 1.5 years after casting of the concrete. The shrinkage stress of wall was approximately 1.0N/mm2.In addition, shrinkage strain of underground beam was 70 ×10-6 and it's temperature changes ranged from -5 °C to +5 °C throughout a year.
