With discussion by E. Burnett, D. B. Beal, R. H. Wood, and A. L. L. Baker. The moment-rotation results are presented of tests on beams carried out by a number of laboratories working under the auspices of the European Concrete Committee. Idealized diagrams are plotted for comparison, and the basis of these diagrams is given as defining fundamental moment curvature relationships which may be used in ultimate load calculations of frameworks. A simple trial and adjustment method of design is explained in which compatibility of bending moment values and end-slopes can be established by joint by joint procedure. Simplification is effected by separating the sway angle from the total rotation at hinges. This simplification can either be made by joint trial and adjustment procedure or by using the Miiller-Breslau compatibility equations, separating the sway angle, which greatly simplifies these equations.
