The introduction of joints between supports in brickwork walls to accommodate in-plane movement leads to a reduction in the resistance of the walls to wind load. The introduction to the bed joints of dowels that allow in-plane movement and restrict out-of-plane movement has been investigated and tests on small panels and wallettes were carried out to demonstrate the feasibility of the use of dowels. The results from those and tests on a full size wall suggest that when suitable dowels are used across the joint the assumption that there is no loss in lateral load resistance is reasonable.
