Abstract:An experimental investigation of the flexural yield criterion for reinforced concrete elements subjected to biaxial bending has been in progress at the University of Illinois, Urbana, since 1965. The over-all objective of this report is to summarize the information obtained. The specific objectives are: (1) To present the general formulation of the yield criterion for reinforced concrete slabs subjected to biaxial loading. (2) To provide a graphical solution, in polar coordinates, ofthe yield criterion. (3) To present procedures for predicting the behavior of reinforced concrete slabs subjected to different loading conditions and at variious stages of loading. (4) To develop a general method to determine the flexibility of slab elements subjected to different loading conditions. (5) To describe the experimental studies carried out to test the yield criterion presented. The yield criterion presented here is applicable to isotropically and nonisotropically reinforced concrete slabs subjected to any combination of external moments. Although emphasis is placed on the yield capacity, procedures are also presented for the determination of the response at any stage of loading.
