摘要
The paper presents a numerical comparative study which is concerned with the behavior of a steel hollow section portal frame exposed to elevated temperatures while considering the effect of both thermal and structural responses incorporating material and geometric nonlinearities. The work provides a study of deformations and stresses affecting the failure behavior of a solved portal frame. The failure temperature is evaluated while respecting variable material characteristics in time of growing temperature. This work presents an investigation of the portal frame with the uniform and non-uniform temperature distribution over the height of the rafter using finite element software SCIA Engineer.
