Concrete beams with large openings are often designed in a simple and global way ignoring a lot of important parameters. In order to identify and assess these parameters a comprehensive study using the Finite Element Method with nonlinear material properties simulating an innovative testing sheme has been performed. The main focus lays on openings located in areas with high shear stresses. For such openings little information is available. The presented results will show that the design of beams with large openings can be done in a more reliable way in the future. A practical design concept will be developed which fits the ultimate and the serviceability limit state.
