TRIAL CONSTRUCTION TEST OF RC FRAMES WITH BRB AND LONG-TERM MEASUREMENT OF TENSION OF ANCHOR PC RODS

Abstract

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.
