14. Coupled thermal and structural analysis of steel columns under fire condition / Análise termoestrutural de pilares de aço em situação de incêndio
The most part of materials whose constitute fire protection elements or structural elements, such as steel columns, when exposed to high temperature have their strength and elasticity modulus reduced caused by thermal action. Therefore the structure can collapse earlier than in an ambient temperature situation. Based in this aspect, the objective of the pres
