Analysis of the limit state of mounting brackets for metal siding panels

The deformation of the mounting bracket for metal siding panels and flexible metal roofing is considered by the finite element method. We obtain the limiting values of the weight and wind load by criteria of the start of material plastic flow and of limiting equilibrium state. On the basis of the analysis of kinetics of strain stress state a new variant of the structure, which has a high load capacity and less labor intensive, is given.
