%X Concrete thermal stress determination has been a difficult scientific problem committed to resolving by researchers. According to operational principle of vibrating wire strain meter, a formula for determining concrete thermal stress was derived based on observational data from vibrating wire strain meter. Applying direct temperature action on concrete specimen by using electrical ribbon heater, experimental determination of thermal stress was carried out under simulated elastic restraint conditions. Relation between the revision coefficient in the formula and temperature variation was determined based on test results. Test results show that vibrating wire strain meter can be used as an instrument to measure concrete thermal stress caused by uniform temperature action, the calculated thermal stress based on formula is consistent well with the measured value.
