Reinforced concrete roof frames as a typical construction form of the post-war period

In the central and eastern part of Germany, reinforced concrete roof structures form a distinctive type of building construction. The lack of timber was the main reason for the design and establishment of such structures at that time. Especially in the 1950s and 1960s, precast concrete companies developed system solutions for roofs of various spans. Around 1950, such constructions were called "Sprossendach" and implemented in only slightly engineered manner. In subsequent years, such roof structures became more systematic and were converted to an almost complete prefabrication and simultaneously qualitatively improved. This paper presents an analysis of selected reinforced concrete roof constructions in Central and East Germany. In the result, the 50-year-old structures have comparatively little damage. However, despite their quite favourable long-term behaviour, this construction type has not enforced due to the quite high expenses for planning and installation.
