摘要: Many masonry structures have cracking problems after earthquake exposure. Rapid and reliable rehabilitation of such is necessary for disaster relief purposes. To improve current methods strengthening with using fiber-reinforced polymer, an investigation the a scaled five-story structure built concrete perforated bricks was conducted. The initially tested on shake table, from which its displacement, acceleration responses, were recorded. partially damaged subjected to rapid (in less than 3 days) basaltic polymer (BFRP) because low elastic modulus high strength (good compatibility substrate). carefully designed, special anchorage measures used first floor ensure effect externally bonded BFRP stripped sheets. strengthened then retested table quantify effect. By comparing performance during two tests, it found that sheets worked well structure, seismic improved significantly.
