Abstract

On September 11 2001, the twin towers of World Trade Centre were struck by two hijacked airplanes. Despite severe local damage induced by the impact, the towers were able to sustain 103 and 56 minutes of the subsequent fire. The purpose of this study is to contribute to the understanding of the behaviour of WTC 1 tower, during the events, in structural fire engineering terms. Using FE package VULCAN, the structural mechanism of the typical long-span composite floor trusses in fire is explained under a variety of scenarios, varying boundary condition, degree of protection and loading. The results are presented as graphs of deflections against time.
