Abstract

This paper investigates the performance of individual floor trusses of the type used at the World Trade Center using software developed over a number of years to model the behaviour of steel and composite framed structures in fire. A variety of scenarios are considered, including different truss forms, degree of protection, and span length, and load ratio. Issues which are considered include the identification of critical truss members, the interaction between flexural behaviour and catenary action at increasing levels of deflection, and the forces which develop in the connections. Results are generally presented as graphs of increasing deflection with temperature or time, and recommendations are given regarding the use of such structural forms for different fire resistance requirements.
