AbstractThis paper presents background data and recommendations needed to help chart future action in formulating rules for codes of practice and research in the field of large panel structures with particular emphasis on all aspects of progressive collapse. All the unusual and accidental loads that can cause progressive collapse are presented and their nature and damage potential discussed. Gas explosions as a cause of progressive collapse are comprehensively treated in light of the British experience with the Ronan Point Disaster and the subsequent legislation leading to the Fifth Amendment of the Building Regulations 1970. British and European thinking and practice are compared. With this as background the current Canadian approach for the prevention of progressive collapse, as given in the National Building Code of Canada, 1970, is appraised.
