COMPATIBLE STRESS AND CRACKING IN REINFORCED CONCRETE MEMBRANES WITH MULTIDIRECTIONAL REINFORCEMENT

A methodology is provided for evaluating the design quantities necessary for designing membrane elements of concrete shearwalls and shells with multidirectional renforcement against inplane forces. The mode of failure - ductile, ductile-brittle, or brittle - is determined as are the critical loads and associated stresses in the reinforcement and concrete and the extent of cracking. Toward this end, a set of equations, each involving one unknown parameter, is applied interactively to convergence, which is shown by example to be rapid. The basis for omitting shear at the crack surfaces and for using continuum strain equations in the cracked concrete matrix is demonstrated. An illustrative example is incldued.
