Three-dimensional modelling of two full-scale fire tests on a composite building

Outlines the main features of a computer program, VULCAN, developed at the University of Sheffield for 3-dimensional analysis of the structural behaviour of composite and steel framed buildings in fire. Describes a number of parametric studies carried out to investigate the influence of the rigidity of the connections used and the floor slab details on the behaviour of the structure in fire conditions. At very high temperatures the floor slab becomes the main load bearing element, whose strength and stiffness are crucial to the integrity of the fire compartment. (Original abstract - amended)
