Flächen- und Schalentragwerke (Surface and shell structures)

Topic

The lecture Area and Shell Structures deals with slabs, folded structures and shells as important structural elements in civil engineering. The theoretical part focuses on the field of application, the equilibrium behavior as well as on useful panels and structural methods. The load-bearing behavior of shell structures is derived from illustrative and analytical solutions. The numerical part is introduced by the programming of a bending beam, which is extended for elastic bedding. This prepares the understanding and programming of the elastically bedded slab. This can be placed in the context of commercial software used to study folded structures and shells.
