Temperature and structural analysis of omega clip

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.
