The performance of cleated, semi-rigid connections is predicted'in two stages starting with the analyses of models in which the effects of prying action are simulated by a spring-roller arrangement. These analyses establish nonlinear relationships between moment and rotation which are appropriate to all types of moment connection. In order to correlate the theoretical results with the performance of proto-type connections the former are modified empirically to evaluate the characteristics of the spring-roller arrangement. The experimental data used for the empirical analyses consists of the work of the Steel Structures Research Committee (1929-36) and the experimental investigations, of ordinary black bolted connections undertaken as a part of this project. The'procedures for incorporating the non-linear momentrotation relationships into the slope-deflection method of frame analysis are outlined and computer programs are developed for a whole rectangular frame and a limited frame. The programs can accommodate any combination of rigid, linear and non-linear semi-rigid connections. By taking advantage of the restraining moments at the ends of the beams, it is shown that cleated connections can be credited with a greater economic advantage than they are at present. The design of the beams and connections can be facilitated by using design charts whose construction is outlined in detail. A small number of these charts are presented and used to illustrate the simplicity of this design approach.
