Samenvatting

For the determination of the moment capacity of cold-formed steel angles loaded by masonry veneers, allowance should be made for local buckling of the individual legs of the lintel. In the Dutch code for steel structures a reduction factor for local lateral buckling is given in design tables. These values are based on the mechanical behavior of unrestrained steel plates which is a conservative approach. In the case of steel lintels supporting masonry veneer walls, which may not horizontally deflect due to fixation by the wall ties, local buckling of the vertical leg of the steel angle in the direction of the veneer wall is restrained by the veneer wall itself. This phenomenon may be taken into account according to the European code for steel structures Eurocode 3 (EC3), which can be done by using the finite strip program CUFSM or finite element calculations. In this research the results of calculations according to different codes and finite element modeling and the results of a preliminary experiment have been compared. Depending on the adopted assumptions a considerable increase in moment capacity of the cold-formed steel lintels has been recognized.
