Pseudo-dynamic testing of unreinforced masonry building with flexible diaphragm and comparison with existing procedures.
Construction and Building Materials, May, 2006 by Bruneau, Michel; Paquette, Jocelyn
Abstract
A full-scale one-story unreinforced brick masonry specimen having a wood diaphragm was subjected to earthquake excitations using pseudo-dynamic testing. The specimen was designed to better understand the flexible-floor/rigid-wall interaction, the impact of wall continuity at the building corners and the effect of a relatively weak diaphragm on the expected seismic behavior. The unreinforced masonry walls of this building were also repaired with fiberglass materials and re-tested. The overall building was found to be relatively resilient to earthquake excitation, even though cracking was extensive. The repair procedure was demonstrated to enhance this behavior. It was found that even though the diaphragm did not experience significant inelastic...
