GMNIA with strain limits based fire design of steel structures
Qualification: Doctor of Philosophy in Engineering (PhD)
Supervisor: Dr Merih Kucukler
In this PhD project, an advanced structural steel fire design approach based on Geometrically and Materially Nonlinear Analyses with Imperfections (GMNIA) of steel structures and adopting strain limits will be established.
In the proposed fire design approach, GMNIA of steel structures will be carried out using beam finite elements, thereby exploiting their computational efficiency. Stain limits will be imposed on cross-sections of steel structures to account for the detrimental effects of local buckling on the structural resistances. Nonlinear shell finite element models of steel structures with the capability of simulating their structural behaviour in different fire scenarios will be created by means of the finite element modelling software ABAQUS.
The accuracy of the developed GMNIA with strain limits based fire design approach will be comprehensively verified using the benchmark structural performance data obtained through shell finite element modelling. The developed GMNIA with strain limits based fire design approach will provide a modern, streamlined and advanced structural steel fire design framework, (i) offering a performance-based fire design of steel structures and (ii) enabling structural engineers to visualise and understand the complex behaviour of steel structures in various fire scenarios.k opens in a new windowLink opens in a new window
