ABSTRACT
This chapter presents experimental and numerical studies on pre-damaged and post-damaged collar-jointed masonry walls subjected to external loading. Collar joint masonry walls were tested by applying a horizontal and vertical point load at the top left hand side of the "reference" wall. The load was applied to the wall using two hydraulic rams and was distributed through two thick steel spreader plates which were embedded in mortar on the top left hand corner of the brickwork panel. The bond strength of interface 2 is stronger because the collar joint and second leaf were cured together, which can provide a better bond effect. A series of experimental studies on pre-damaged and post-damaged double-leaf brickwork masonry wall panels have been conducted. The collar-jointed masonry walls were constructed by building a wall parallel to an existing single-leaf wall and tying them together using the collar joint technique.
