Abstract : A survey of residential buildings in central Ottawa revealed a wide range of damage intensity due to settlement. The maximum angular deformation for no damage conditions in brick houses appeared to be 1/180. Greater angular deformations produced cracks in the exterior walls. Laboratory racking tests carried out by the U.S. National Bureau of Standards showed that masonry walls could only withstand deformations of 1/1000, although wood frame walls could withstand much greater deformations without damage.
