Hybrid truss/plane shell structures

Dry joined with high-performance concrete

The priority program of the German Research Foundation (DFG) – within the scope of the project “Lightweight building with concrete” – examines the joining of very slender precast construction elements made of steel-fiber-reinforced ultra-high-performance concrete (UHPFRC) to very lightweight loadbearing structures. The focus here is on dry mechanical coupling of trusses in their axis and in multi-dimensional node elements, as well as on plane elements with linear connection. If it is possible to successfully design form-fitting load-transferring connections in such a manner that shear,...
