Other members of the design teams: architects, developers and owners, will find the book a useful reference. The needs of researchers, lecturers and students of the subject will also be satisfied by this simple presentation of the underlying theory. The practical constraints and considerations of the underlying engineering are also indicated."--BOOK JACKET.
