Chapter 34: Developments in masonry

Masonry has developed continually over many years and in recent years changes in regulations have led to changes which have become part of modern practice. In 1997 the Masonry Industry Alliance developed a strategy for innovation and research for the subsequent 10 years. In 2007 the progress against that strategy was reviewed. Since that date, some further developments have taken place perhaps most significantly those in relation to the revisions to British Standard Codes of Practice and the Eurocode which will shortly replace the British Code. Some developments have stayed at the research phase, for example the design of pocket-type retaining walls with wide pocket spacings; some have been overtaken such as Traditional Plus; and some have continually evolved such as the development of ties. The development of the WI-beam system is a classic solution to a construction problem which requires a purpose drafted design guide. Masonry has developed not only in terms of new build but also the sympathetic treatment and change of use of existing buildings has transformed the centres of many of our cities. Masonry has moved forward in a variety of ways: through research-based projects, practical solutions, materials use and development and understanding of existing masonry. All are relevant and are underpinned by the development of Codes and Best Practice Guides.
