The Minaret of the Great Mosque in Algiers,a Structural Challenge

Open Journal of Civil Engineering 2013年第2期3卷 27-39页

作者： Dan Constantinescu dietlinde kober Krebs&Kiefer Consulting Civil Engineers KarlsruheGermany

The Great Mosque in Algiers will be the third largest mosque in the world and its minaret the highest. The region has a high seismic risk. The project designed by a German team of architects and engineers is under construction and will be finished by 2016. Due to the minaret slenderness and to the special composite structure chosen to withstand lateral loading, the structural design faced some challenging aspects. The paper presents the design philosophy, some significant structural features and details of the minaret structure.
