Summary

In this paper the problems emerging during numerical modelling of a novel structural system, composed of ultra-lightweight concrete and cold-formed steel elements are introduced. The aim of the complex numerical modelling was to develop a model to clearly identify the structural behaviour modes and to widen the range of experimental results. The numerical model described was built in ANSYS, taking into account the material nonlinearities along with geometric imperfections and features of contact surfaces between concrete and steel. These parameters were set based on experimental results. Numerical model and results are presented both for column and beam elements. It was found that the targeted complex numerical model can be developed, but it has such great computational demand that it is not efficient to use in a parametric study.
