Tall building collapse mechanisms initiated by fire
This paper introduces the hypothesis of two possible failure mechanisms for tall buildings in multiple floor fires. This paper extends the previous work done on the WTC towers by investigating more "generic" tall building frames made of standard universal beam and column sections to determine whether the same collapse mechanisms are obtained. The outcome of this paper enables the development of a simple stability assessment method for tall buildings in multiple floor fires
Collapse scenarios of WTC 1 & 2 with extension to generic tall buildings
This paper presents a summary of the authorâs investigation into the collapse of tall buildings.
A large number of computational analyses have been carried out at the University of Edinburgh (UoE) over the last 4 years in order to understand the collapse of the tall buildings of the World Trade Center (WTC) complex on September 11, 2001 following the terrorist attacks that day. The aim of these analyses has no been to carry out a âforensicâ investigation (as this was done by official US government sponsored investigation by NIST, see wtc.nist.gov). The primary purpose of the UoE investigations was to understand the global collapse mechanisms of tall buildings as a result of extensive (involving multiple floors) fires and from these analyses identify any âgenericâ collapse mechanisms that may or may not
exist. Such identification will allow the development of new design methods resulting in
enhancing the safety and robustness of tall buildings again fire
