This report presents studies on the construction performance of connecting buckling restrained braces in RC frames and the decrease in the tension of anchor PC rods. First, a construction test considering actual building conditions was carried out. From the test result, problems in actual construction were identified and the possible solutions were examined. In addition, long-term measurement of the tension in the anchor PC steel rods was conducted for one year. From the results of the long-term measurement, the decrease in the tension of PC rods was analyzed, and the method for designing anchor PC rods was suggested.
