| Summary: | 碩士 === 國立臺北科技大學 === 土木與防災研究所 === 101 === An original reinforced concrete column and its four strengthened specimens, where two are RC jacketing columns and the other two are columns with installing wing walls, were tested in this study. The original column was designed to comply with the old design standards and thus the usual detailing deficiencies in existing school buildings can be simulated. Two different structural details were chosen to fabricate the full-scale specimens for both seismic retrofitting techniques. The major difference in structural details for RC jacketing columns is whether or not the transverse adhesive anchors are used to provide a smooth transfer of actions between existing column and new jacket. Whereas, the major difference in structural details for columns with wing walls is the arrangement of transverse and longitudinal adhesive anchors in one row or two rows between new and existing concrete. The seismic performance of the five test specimens are compared and discussed, and the structural details for RC jacketing columns and columns with installing wing walls are recommended for practice.
