Abstract: To study the in-plane seismic resistance of multi-story masonry coupled walls, 6 full-scale reinforced masonry specimens, each two stories high, are being constructed and tested in the laboratory as part of the TCCMAR program. All specimens will be of fully grouted hollow concrete masonry. Three specimens are pairs of walls, coupled by floor slabs with and without lintels. In this paper, the design, construction, and testing of the first coupled wall specimen (Specimen 2a) is described. Preliminary test results are presented, discussed, and compared with analytical predictions.
