AbstractThe partial collapse of the Ronan Point high-rise apartment building in England in 1968 showed, most dramatically, the need for a new consideration in structural design-resistance to progressive collapse initiated by local failure due to abnormal loads. In this paper examples will be discussed of progressive collapses that have occurred in the past and of abnormal loads which can initiate progressive collapse. Some statistics are also included based on a study of news reports. This information provides a rough measure of existing situations susceptible to progressive collapse. Building Code provisions on progressive collapse will also be reviewed briefly. The difficult problem of how to design or analyze structures for progressive collapse will, however, not be discussed.
