Nesta publicação aborda-se o comportamento estrutural de vários tipos de colunas mistas, com especial atenção aos princípios base, aos modelos de cálculo e Às comparações entre resultados teóricos e práticos. O apendix, que inclui cerca de 100 diagranas, permite um dimensionamento rápido e económico para a classes de fogo F30 e F120.
The structural behaviour in fire of composite columns consisting of rolled H-profiles encased in concrete, rolled H-profiles with concrete between the flanges and concrete filled hollow sections is treated with special regard to the basis assumptions and principles, the calculation models, comparisons between theoretical and experimental results and easily applicable design tables. The appendix with about 100 diagrams enables a quick and economical fire resistance design for the fire classes F30 and F120.
