Die Bemessung vorwiegend ruhend beanspruchter Schweißverbindungen von Aluminiumtragwerken nach DIN EN 1999-1-1

Design of predominantly statically loaded welded connections of aluminium structures according to DIN EN 1999-1-1.

The design of aluminium structures according to DIN EN 1999-1-1 is different with respect to many design principles of DIN 4113 in general as well as especially for welded connections. Non-contradicting existing German design rules and deficiencies (missing design provisions) which became obvious with the application of DIN EN 1999-1-1 in daily practice required and will require NCI-regulations with supplemental design rules and comments in the National Annex and its amendments. The regulations of DIN EN 1090-3 [5] for execution and testing of welds are discussed in connection with the design rules. This is important since the degree of nondestructive testing of welds according to DIN EN 1090-3 [5] depends on the utilization factor (utilization range) and the nature of structure (execution class). Thus it indirectly determines the design resistance which is needed by the designing engineer.
