Specifications and practical examples

Structural precast construction in seismic areas

Design and construction in German earthquake areas had previously been governed by DIN 4149 [1]. This standard will be superseded by DIN EN 1998-1 (Eurocode 8) [2, 3] and the corresponding National Annex [4]. The new generation of standards will contain comprehensive guidance regarding geotechnical correlations, resulting actions on structures and design rules that ensure earthquake-resistant construction. The magnitude of seismic actions depends on the soil class, ground class and earthquake zone in which the relevant site is located. Ground conditions influence the elastic response spectrum...
