Testing of a Full-Scale Unreinforced Masonry Building Following Seismic Strengthening
Publication: Journal of Structural Engineering
Volume 133, Issue 9
Abstract
To investigate the effectiveness of several seismic strengthening techniques, a full-scale unreinforced masonry (URM) structure was subjected to slowly applied lateral load reversals after the application of fiber reinforced plastic overlays, near surface mounted rods, and vertical posttensioning. Results showed that all techniques were effective for improving the seismic resistance of the previously tested URM building structure. Each system either increased the lateral in-plane strength and/or provided continuity of pier and spandrel elements over increased lateral displacements. In addition, the response of the test structure (overall height to base ratio of approximately one) showed that global issues such as flange effects, the effects of overturning moment, and global rocking can be substantial and must be considered.
