Wieviel Sicherheit braucht das Mauerwerk?

How much safety needs masonry?

Over the decades, the German standard for masonry DIN 1053 has been updated several times and adapted to new findings and requirements [1]-[7]. For certain time the part -100 [7] for analysis and design using partial safety concept is available. This year the transition to the EC 6, which also bases on the design according to the method of Iimit states is approaching. Consistently one has done his best to update the standard on the basis of a widely recognized safety Ievei. The analysis and design has been refined gradually. Especially masonry members under horizontal Ioads are considered more sharply with the transition to the partial safety concept. The more intensive calculation and detailed consideration of the differentiated effects should also be worthwhile economically.
This contribution Iooks back at the safety Ievei that has been agreed on with the issue of the DIN 1053 of 1990 [3] by the persans involved. After that the question is then followed whether this safety Ievei that was accepted over the past 20 years, could not also serve as Basis for calibration in the transition to the partial safety concept.
The considerations are limited to predominantly vertical loaded masonry members.
