Abstract

Continuous shear connectors with different shapes have been developed and used in composite members during the last two decades. At the Chair of Concrete and Masonry Structures of the Technische Universität München (TUM) experimental and numerical investigations have been carried out to determine the structural behavior of continuous shear connectors with a clothoidal shape (MCL-shape) in thin-walled elements made of Ultra-High Performance Concrete (UHPC). It was observed that MCL-strips possess a high shear-carrying capacity in UHPC and show ductile load-deforrnation behaviour at the same time. However, if concrete failure occurs, the failure mode is a brittle splitting of the filigree UHPC-elements. Therefore, the thickness and yield strength of the MCL-strip have to be chosen in accordance to the thickness of the thin UHPC to provoke a steel failure or a higher safety margin has to be considered for concrete failure.
