This paper discussed the monitoring of the temperature changes and strain changes of a 5-story reinforce concrete building by a fiber Bragg grating(FBG) sensor system in building construction course.Based on the project results,it is showed that the packaged FBG used in mea-(surement) is feasible and superior to monitor the change of interior temperatare and strain of concrete structure for a long period.This project also provides some useful advice for structure health monitoring.
