Vulcan is a finite element analysis (FEA) program, which is capable of modelling the global 3-dimensional behaviour of composite steel-framed buildings under fire conditions. The analysis considers whole structure action and includes geometrical and material non-linearity within its beam-column and slab elements, with full membrane action in the slabs.
Standard stress-strain curves and full thermal expansion characteristics are incorporated as functions of temperature for both steel and concrete, with uniform or non-uniform temperature distributions. The orthotropic nature of composite deck slabs is represented using an effective-stiffness concept, and options for semi-rigid connections and partial interaction between steel sections and slabs are provided.
Vulcan software has been developed specifically for the analysis of building performance in fire conditions. It differs from traditional, commercial FEA packages in its simplicity and speed of use. Users do not need to be experts in finite element analysis, and a graphical user interface makes data input and interpretation of results quick and easy.
In 2005 Vulcan was presented with two Professional IT Awards by the British Computer Society.
In Addition, Vulcan was Highly Commended at the Association for Consultancy and Engineering (ACE) Awards 2010 in the Research Category.
