Abstract:
A yield line analysis is presented for simply supported rectangular concrete slabs (isotropically reinforced) with central rectangular openings, under uniformly distributed load. The three possible yield line patterns (mechanisms) are analyzed and design diagrams derived for rapid determina-tion of the correct mechanism and the required ultimate moment. Numerical examples are provided.
