RC Roof Structures from Post-war Time

Reinforced concrete roof structures represent a historical construction method that was particularly widespread in Central and Eastern Germany in the post-war period. The lack of wood at that time mainly led to the invention of constructions based on typical wooden roof constructions. Particularly in the first two post-war decades, precast concrete companies developed various system solutions for reinforced concrete roofs with different span widths. Initially only implemented in a slightly technical form, it was later possible to systematise such roof structures more strongly and to convert them to extensive prefabrication. Due to the high planning and assembly costs, however, the construction method was not successful in the long run. The results of the analysis in this article show that the RC structures, which are over 50 years old, show comparatively little damage. Due to their rarity, which is quite rare in the meantime, it is worth considering the preservation of this construction as a historical testimony.
