Seismic Performance of Low-Rise Wood-Framed and Reinforced Masonry Buildings with Clay Masonry Veneer

Abstract
This paper describes a coordinated experimental and analytical study that investigated the seismic performance of wood-stud construction with clay masonry veneer and of RC masonry construction with clay masonry veneer designed according to current U.S. building codes. As part of this study, two 1-story buildings were tested on a shaking table. Both had clay veneer on the outside. One had wood-frame walls for the backing and load-resisting system, whereas the other had RC masonry walls. With one exception, the behavior of the veneer in the wood-framed building was satisfactory up to levels of shaking consistent with the design level earthquake. That exception was related to the relatively low pullout strength in wet wood of the conventional nails used to attach the veneer connectors to the wood-stud wall. On the basis of this study, code changes have been implemented to require the use of higher-capacity fasteners for such applications. The wood-frame building specimen itself did not collapse under levels of shaking consistent with the maximum considered earthquake. Behavior of the RC masonry building and the veneer on that building was satisfactory up to levels of shaking well in excess of the maximum considered earthquake.
