APPLICATIONS SHEARING AND TENSILE PLATES | 199
Connection of the intermediate layer The intermediate layer must be force-fit to the timber component (non-moving intermediate layer). In other cases and generally in the case of movable intermediate layers, the load-bearing capacity of the connecting element should be determined individually for the respective connection. Connecting element for intermediate layers The length must be selected so that the profiled length (insert depth) behind the intermediate layer corresponds at least to the length specified in the statics tables. Connection to concrete The load-bearing capacity for fixing in concrete must be verified separately in accordance with the requirements of the selected anchor, bolt, screw with Ø16mm. Edge spacing in the concrete component must be selected and verified in accordance with the selected connecting elements in the concrete and the associated approval/ETA.

Combined stress For GH screws under combined stress of pulling out and shearing, the following condition must be met:
Load capacities of steel sheet In the statics tables, the following proof of load capacity has been considered for the steel plate: Tensile and shearing load capacity of steel, perforated soffit Design values To determine the design value of the respective connector, the decisive design value from the connection is determined.
Design value of “timber” failure
Design value of “steel” failure
Design tablen Load capacities in timber in kN For the connections, the assumption is made that the interconnected components are held against twisting and that eccentric load situations are therefore excluded. The number of nails must be used under consideration of the specified nail/screw patterns.
