The latest edition of the reference for structural engineers who design masonry structures reflects changes in the industry's practices; current health and safety standards; and new regulatory requirements for heat loss, noise transmission, and disproportionate collapse. The drawings have been changed from technical drawing format to an illustrative format to better clarify theoretical and practical principles and processes.
