The exact analysis of reinforced concrete deep beams with web openings presents formidable problems. However, the ultimate shear strengths of such beams can be predicted with reasonable accuracy by using a simple structural idealization. The idealization was based on pilot tests on 24 beams, but has now been checked against a further 32 tests covering a much wider range of web openings and web-reinforcement patterns. An improved shear strength equation is presented and design hints are given.
