Abstract: Paper presents creep buckling numerical modeling of steel beam-type structure.
Afterwards, for geometrically and materially nonlinear creep buckling analysis shell finite element model is used.
For a creep buckling analysis, the frame is loaded with three different constant forces: 4 MN (it is about 0.5[F.sub.cr]), 5.75 MN (it is about 0.7[F.sub.cr]) and 7.4 MN (it is about 0.9[F.sub.cr]).
The critical creep buckling times obtained for different chemical composition carbon steels at different temperatures are listed in Table 2.
Numerical simulation of creep buckling is a fast way of prediction of such phenomena.
Even though this analysis includes only creep buckling at constant temperature levels, with slight modifications it is possible to expand it to non-constant temperature environment conditions e.g.
Future research will also encompass development of a creep buckling computer algorithm based on beam finite elements.
