Modeling of the dynamic behavior of brick veneer subjected to earthquake ground motions

Abstract eng:
The use of brick veneer with wood-stud frame construction is common in residential houses in the US. This paper presents an analysis of the seismic performance of brick veneer in wood-stud walls. Computational models have been developed and verified in light of the results of shake table experiments conducted on single wall segment assemblies representative of low-rise constructions. The experimental and analytical studies are part of a research project sponsored by the US National Science Foundation under the auspices of the George E. Brown, Jr. Network for Earthquake Engineering Simulation Program. Nonlinear and linear beam elements are used to model the brick veneer and the wood-stud backing wall, respectively. Truss elements with appropriate hysteretic rules are used to model the veneer anchors. Nonlinear time history analyses have been conducted with models representing different wall configurations and having different anchor types and spacings. The displacements and accelerations of the veneer and backing walls obtained from the analyses have shown good correlation with the experimental results. The models account for the dynamic interaction between the veneer and the backing, provide an estimation of the strengths of the anchors and show the effect of veneer cracking on the distribution of anchor forces.
