Sažetak
The paper presents an application of a newly developed implicit procedure for including steel creep strain into structural fire analysis through modelling a series of stationary fire tests. An implicit modelling procedure is incorporated into customized structural fire analysis software. Four stationary fire tests on simply supported, steel members were modelled using strain modified stress-stress curves. Strain modified curve was obtained by adding the creep strain directly into the steel stationary stress- strain material curve. The proposed implicit procedure in this manner attempts to create an equivalent transient stress-strain curve from the provided stationary stress-strain curve. The proposed implicit procedure was able to provide satisfactory prediction of member deflections in the temperature region of 400- 700°C.
