Structural Masonry Designers' Manual

Description:
This major handbook covers the structural use of brick and blockwork. A major feature is a series of step-by-step design examples of typical elements and buildings. The book has been revised to include updates to the code of practice BS 5628:2000-2 and the 2004 version of Part A of the Building Regulations. New information on sustainability issues, innovation in masonry, health and safety issues and technical developments has been added.

Review:
'This is essential reading for all civil structural design offices involved with masonry design and is now established as the standard work on the subject.' - New Civil Engineer 'This is an excellent reference ... especially for sites with difficult ground conditions.' - The Structural Engineer 'Looks crisp and with a modern style of illustration, is easy to read for a technical manual. As a full and comprehensive review of structural masonry, authoritatively written and covering most of the aspects likely to be encountered in practice, it is a hugely useful manual.' Institution of Structural Engineers 'This book is a precious gift for the consulting/ design engineers and students.' Journal of Structural Engineering
