Abnormal loading on buildings and progressive collapse

Robustness of Frame Structures

“…However, due to the wide exposure received by this accident, in the following years, this type of failure attracted substantial attention both from researchers and code authorities. A large number of publications considering progressive collapse, its causes, and possible preventive measures appeared during the 1970s [4,5,6,7,8,9,10,11]. It was also reflected in building codes, a number of which included provisions aimed at reducing risk of progressive collapse [12,13].…”

The Incidence of abnormal loading in residential buildings

“…Somes [32] has attempted to classify the various abnormal loadings as follov^s: It is likely that the greatest number of abnormal loadings occur during wartime. McGuire [25] has summarized one British report on wartime experiences as follows:…”

The incidence of abnormal loading in residential buildings

“…The chief criterion for selection of the loadings studied was plausibility. In this regard the data provided by Ligtenberg [24], Allen and Schriever [4], and the various classifications by Somes [32] and Burnett [13] were helpful in selecting the abnormal loadings described herein.…”
