events and the resulting effects on the structural integrity are of considerable concern. In addition to the implications for design, quantitative information regarding the nature of the strength loss is required to make decisions regarding, for example, the seaworthiness of a ship that has sustained fire damage. Many of the thermal properties of composites related to fire have been thoroughly studied and are well understood, including ignition times, heat release rates, smoke production rates and gas emissions (e.g., Sorathia et al. [2], Gibson and Hume [3]). Also, recent work on the post-fire residual properties (Mouritz and Gardiner [4]) showed large reductions to the edgewise compression capacity of phenolic-based sandwich composites despite their good flame resistance. However, an important gap that remains in the understanding of composites is their response and structural integrity due to the combined effect of mechanical and thermal loading due to fire. The present article addresses this issue on the example of a symmetrically laminated composite column. It is illustrated that such column that would experience bifurcation buckling as a result of compressive loading exhibits bending in the presence of fire. The article expands the previous analysis [5] providing detailed explanations of the solution methodologies for different boundary conditions and nonlinear and linear formulations.
