A suffiient redundany has to be ensured, that the failure of a single fastening will not lead to ollapse of the entire system. Reommended loads are based on failure of the fastener anhorage in the onrete. Thikness and quality of the fastened material may lower the loadings. Observane of all pre-drilling requirements, fastened thikness limits, and reommended details. The reommended loads in the table refer to the resistane of the individual fastening and may not be the same as the loads F N and F V ating on the fastened part.
