Abstract:
A methodology is provided for evaluating the design quantities necessary for the design of reinforced concrete shearwalls and shells subjected to in-plane forces. The overall behavior of the membrane element in such structures is shown to be governed by failure in one of three possible modes: ductile, ductile-brittle, or brittle. The methodology determines the mode of failure, the failure loading, the associated critical stresses in reinforcement and concrete, and the extent of cracking. The membrane crushing strengths associated with the brittle and ductile-brittle modesare evaluated. The reliability of the methodology is confirmed by satisfactory comparison between predicted and test results. An illustrative example is included.
