A computer oriented method is described for determining the dynamic response of rectangular plane frames with nonrigid beam-to-column connections. The dynamic loads may be either lateral forces applied directly to the frame or inertia forces due to lateral acceleration of the ground. The moment-rotation relationships for the nonrigid connections are assumed to be bilinear, and the effects of elasto-plastic behavior in the columns, finite joint sizes, and initial vertical loads are included in the analysis. The results of analyses of a 10-story frame show that both lateral displacements and member end-actions are influenced to a large extent by the stifnesses of the connections.
