Verifiering av Kedertakstolen

Sammanfattning: The Kedertruss is the loadbearing part in the Keder weatherprotectionsystem and it has been analyzed concerning its loadbearing capacity. The Kedertruss is produced and manufactured by Wilhelm Layher GmbH & Co. KG and this report has been made for their Swedish division Layher AB.  The Kedertruss, designed in Germany according to German designcode, has been recalculated concerning Swedish conditions according to Eurocodes and a ongoing European standardization project. The two-dimensional program Winstatik Frame Analysis has been used for evaluation of load effects. Capacity has been calculated by hand-calculations and it has been verified that the Kedertruss in its larger spans isn’t able to withstand the loads. The main problem is the greater snowloads which has been proofed to be the most unfavorable load for the Kedertruss. Apart from the commission from Layher AB a parametric controlled model of the Kedertruss has been made in Revit Structure
