In building construction, reinforced concrete floors are frequently used as installation space for building services. Horizontal line distribution is one of the major causes for cross-sectional weakening, thus leading to a significant reduction in the shear force resistance of reinforced concrete floors without shear reinforcement. In recent years, an in-depth study has been conducted at TU Kaiserslautern on the shear force resistance of reinforced concrete floors with integrated line installations. The design concepts developed are available to the building industry as part of the national...
