IHS BRE Press Handbook for The Structural Assessment of Large Panel System (lps) Dwelling Blocks for Accidental Loading BR511

Get new guidance on the structural assessment and strengthening options for large panel system (LPS) dwelling blocks, focusing primarily on their resistance to accidental loading associated with gas explosions. Author: S Matthews, B Reeves Publish Date: 7/20/2012 ISBN: 978-1-84806-200-9 Abstract: This handbook presents new guidance on the structural assessment and strengthening options for large panel system (LPS) dwelling blocks, focusing primarily on their resistance to accidental loading associated with gas explosions and supported by extensive background information. The progressive collapse of part of Ronan Point tower block in east London in 1968 was a significant event in structural engineering in relation to the understanding of disproportionate damage to structures. There have been extensive research and investigations since then, including full-scale structural load tests on a block in Liverpool, which are taken fully into account. The handbook: - defines the requirements to be met and the criteria against which the results of a structural assessment of this particular class of building should be judged. These are seen to effectively supersede the previous guidance set down in the Ministry of Housing and Local Government Circulars dating back to 1968. - gives guidance on how to undertake the structural assessments which are required, drawing on previously unpublished technical information including the results of a number of full-scale load tests to failure that give a better appreciation of the actual strength and potential performance of these buildings should they be subject to an internal gas explosion. - details the historic background to these requirements, with these being brought up to date and set in the contemporary philosophical context of the requirements of the recently introduced structural Eurocodes. - explains the risk environment which applies to this class of building. - provides an overview of durability assessment/intervent ion and strengthening options.
