Tapered beam of a steel portal frame is numerically simulated by the finite element method, and the changes of temperature field under the ISO time-temperature curve and local fire are obtained.
In this paper, the element stiffness and consistent geometric 'stiffness matrices for linearly tapered members with arbitrary cross-section have been derived in explicit forms.
