Abstract

Cold-formed thin-walled cross sections are very frequently and efficiently used as secondary construction elements as well as self-supporting cladding systems. Typically, they are used on hall-type buildings and other lightweight structures. The primary advantage of thin-walled cross sections is their ratio between self-weight and load bearing capacity. Another important factor is their easy installation. The main disadvantage of thin-walled cross sections is their low resistance to fire. Their low weight and thin cross section can cause higher temperature increase in the element compared with hot-rolled or welded cross sections. This is undesirable with respect to the load bearing capacity. The article deals with numerical modelling of thin-walled omega clip under temperature and force load. Two calculations—heat passage by radiation and structural analysis using temperature analysis outputs—are combined. The temperature values as input data for the temperature analysis are sourced from the physical experiments conducted.
