Seismic Performance of Clay Masonry Veneer

Abstract eng:
This paper presents an experimental investigation of the out-of-plane seismic behavior of clay brick veneer over wood-stud walls. A series of shaking-table tests was performed on wall panels consisting of a clay brick wythe attached to a wood-stud frame with metal anchors. Different anchor types and spacings conforming to the current design standards in the US were used. Some walls had a window opening and some did not. The walls were tested to failure through shaking in the out-of-plane direction with increasing earthquake ground motion levels. This paper presents a summary of the experimental program and results, design implications, and an appraisal of the current code provisions. The test results indicate that the veneer walls could sustain ground motion levels considerably beyond the maximum considered earthquake.
