Criteria and methodology for the design and capacity evaluation of reinforced concrete membranes are developed using the strength-design method. The proposed criteria and methodology are based on theoretical considerations and the results of two programs of large-scale membrane testing. The crushing strength of membranes under biaxial stress is first evaluated. Criteria for ductile versus brittle membrane failure are then developed for general membrane loading. Equations for the design of membrane reinforcement and for evaluation of capacity of existing membranes are presented. The proposed criteria and predicted capacities are checked against test results with satisfactory agreement.
