Practical Guide to Structural Robustness and Disproportionate Collapse in Buildings

Practical guide to structural robustness and disproportionate collapse in buildings
Incorporating robustness in buildings is essential and a stated aim of most regulations and indeed all material codes worldwide. Yet robustness is not readily defined. This Guide tries to provide common sense advice on what constitutes robustness. It begins with some generic background on the fundamental attributes of robustness and then provides interpretation and practical guidance on the regulations. The second half of the Guide dedicates a chapter to each of the main materials (in situ concrete, precast concrete, steel, timber and masonry) so that material specific issues can be discussed and solutions offered.

This Guide has been prepared in response to a perceived need for more information on structural robustness to address the lack of confidence among designers in the application of building regulation requirements. The Guide is aimed at engineers charged with designing and constructing the relatively low rise everyday building structures that make up the bulk of the profession’s workload. In the UK, these structures would be limited to Class 2 in the guidance to the regulations. This Guide does not cover Class 3 structures.
This Guide generally adopts the methods for achieving robustness as described in Approved Document A, the official guidance to the Building Regulations for England and Wales, and in similar documents for Scotland and Northern Ireland. However, in recognising the transition to Eurocodes, the Guide defines the formal requirements of the Eurocodes and then highlights where these differ from traditional UK practice; thereafter, detailed advice is given on the application of current practice with compliance to British Standards.
