The influence of description of fire curves on the thermal and reliability response of steel structure

The influence of description of fire curves on the thermal and reliability response of steel structure

The paper presents a proposal for the assessment of the reliability of statically determinate steel truss in the persistent and accidental (fire) design situation. The steel truss was modelled as series system from the reliability standpoint. The global Hasofer-Lind reliability index was employed, c...
