1. ABSTRACT
Design methods for posite structures are described in the structural Eurocodes, which are in the process of being converted to full EN standards. The methods now include elements relating to the 'natural fire safety concept' (developed under previous ECSC research programmes - NFSC1 and NFSC2) and provision is also made for use of "advanced calculation models" such as "Computational fluid dynamics" (CFD).
The natural fire safety concept provides a more realistic description of the thermal exposure of structures under "natural fire conditions". The current project builds on this approach by exploiting the techniques putational fluid dynamics (CFD) to develop, verify and apply prehensive engineering methodology for predicting the thermal response of steel ponents.
The main challenge in this application lies in that fact that ponent of interest is typically very small relative to that of the putational domain. When putational
