Abstract

On September 11, 2001, fires began to spread throughout WTC Tower 5. These fires caused numerous steel shear-tab connections to fail causing collapse in part of the tower. This paper discusses the prediction of steel shear tab connection failure (web tear-out mode in this case) as a result of unwanted fire exposures. Both protected and unprotected connections are analyzed using the finite element analysis program, ALGOR. As a result of this research, recommendations for future fire exposed steel connection research and design methodologies will be presented.
