Seismic Masonry Veneer: Quazi-Static Testing of Wood Stud Backed Clay Masonry Veneer Walls
Based on past performance during seismic events, masonry veneers can pose a significant hazard to public safety. Because there is a significant inventory of masonry veneers in the built environment, this risk is substantial and must be quantified and systematically mitigated. In addition, current design provisions must be re-evaluated and refined to ensure that new building construction produces masonry wall assemblies with acceptable seismic performance. To address these concerns a number of researchers have investigated this type of wall system under seismic loading. To extend this work further, an effort is being funded under the George E. Brown Network for Earthquake Engineering Simulation to evaluate the response of masonry veneer systems under seismic loading. One of the goals of this investigation is to develop accurate dynamic wall system models for seismic excitation. These models are to be used to support development of performance based design under frameworks such as those proposed by ATC 58. As a part of this multi-institutional investigation, the performance of clay brick veneer walls constructed with wood stud backing walls are being experimentally evaluated. This phase of the testing program subjected full scale brick veneer/wood stud wall specimens constructed to typical code defined residential configurations to quasi-static cyclic in-plane and out-of-plane loadings. A variety of wall specimen configurations are being evaluated, including variables such as the effects of joint reinforcing, the type and spacing of ties, and the effects of openings. The result of these tests will refine the analytical models being developed and support the development of large scale shake table building specimens that will be evaluated at a later date. The results of the quasi-static out-of-plane loading tests are presented in this paper. The following sections describe the details of the testing program.
