Investigation of punctiform, plane and hybrid joints of textile-reinforced concrete parts

The application of textile-reinforced concrete allows manufacturing of thin-walled, high-strength components. Efficient joints are vitally important for the integration of precast concrete components into structural frameworks. Within the scope of a recent research project, basic punctiform, plane and hybrid joint geometries have been tested. The goals of this study are to avoid any reduction in strength compared with undisturbed components. This paper describes investigations on the tensile strength and failure pattern of different joint geometries. Different types of joints and failure are discussed and an auspicious joint offering nearly the load capacity of the undisturbed specimen is introduced. (c) 2007 Elsevier Ltd. All rights reserved.
