Numerical verification of typical connection of high thin-walled purlins
Original language description
The presented paper deals with numerical analysis focused on the behaviour of high thin-walled purlins of 300 mm height and mainly on the way of their connection to other structural elements. In previous publications, numerical models of purlins with and without a reinforcing clip were presented and verified by a large experimental program. This paper then presents results from numerical models modified so that the purlin is bolted to the clip only at the standoff. This method of connecting the trusses is one of the commonly used methods of truss placement, yet it has not been tested in the experimental program. The numerical models used have optimized and verified boundary conditions and parameters. In this paper, purlins of 300 mm height, 1.89 mm plate thickness and 200 mm bearing width are selected. Two spans of supports 3.0 m and 5.1 m are investigated. According to the results, there is a significant effect of the reinforcing clip on the overall load carrying capacity of the detail of the high thin-walled purlins. The effect of additional bolting of the web of tall thin-walled purlins in the connection detail to the supporting structure has a positive effect on the overall load capacity.
