Concrete Design Guide

摘要

It might seem strange that a series on concrete design should include articles about masonry design. However, much masonry design in the UK uses concrete blocks, made by members of the Concrete Block Association, which is affiliated to the Mineral Products Association. BS EN 1996 (Eurocode 6) covers the design of masonry for buildings and civil engineering works and is organised into four parts. In common with the other material Eurocodes, Part 1-1 covers the structural design rules and Part 1-2 covers structural fire design. Thereafter, there is some divergence from other Eurocodes in that Part 2 covers aspects of design, materials and workmanship while Part 3 looks after the German need for simplified calculation methods. Masonry bridges are not covered by EC6. Each part has a corresponding UK national annex. BS EN 1996-1-1 was first published in 2005 along with BS EN 1996-1-2. BS EN 1996-2 and 1996-3 were published in 2006. The corresponding National Annexes bear the same dates. Corrigenda were issued to Part 1-1 in 2006 and 2009, and in 2012 a new version was published incorporating Amendment 1. While the 2012 changes to BS EN 1996-1-1 are relatively small, the opportunity was taken to update the corresponding UK National Annex based on feedback from use and recalibration of some of the outcomes. The discussion and observations that follow are therefore related to the 2012 version of the UK National Annex to BS EN 1996-1-1.
