Some building codes require single wire joint reinforcement in masonry veneer walls in higher seismic zones. The current investigation examines the effect of joint reinforcement on the embedment performance of one type of brick tie under reversed cyclic loading. The embedded part of the brick tie was tested in small wall elements under three conditions: no joint reinforcement, joint reinforcement not connected to the brick ties, and joint reinforcement connected to the brick ties. Vertical surcharge loads were varied to represent conditions near the top and bottom of a one-story wall. Test procedures, apparatus and instrumentation are described. Test results and modes of failure are presented and discussed.
Key words: Brick, Veneer, Joint Reinforcement, Tie Embedment, Cyclic Loading
