Despite the fact that this book was published in 1998 and is based on the 1994 UBC, it is still the best book on masonry design out there for the practicing engineer. As another reviewer notes, it's useless as far as the actual design is ccncerned and it does assume you know a good bit about what you are doing already, but I am at a lost to find a better book for my newbies.
