Shear friction in cracks of concrete beams under shear and torsion

• Applicant: Professor Dr.-Ing. Günter Axel Rombach

The goal of this research project to get a better knowledge on the transfer of inner forces over cracks in reinforced concrete beams under shear and torsion. First 14 reinforced concrete single beams with different dimensions, concrete compressive strengths and maximum aggregate diameters will be tested under shear and torsion loads. The crack kinematics will be determined by photogrammetry. This method is necessary to determine the crack friction using known models. The experimental and analytical investigations are supported by material non-linear finite element calculations with the software packages Abaqus and ATENA.
