Abstract:This report contains a description of slow and rapid load tests of riveted and bolted column-base and beam-to-column connections, and the results which were obtained. Measurements of load, deflection, strain, and acceleration were taken in order to evaluate the resistance characteristics of the connections. The small number of specimens and variety of connection types limited the scope of the investigation. The tests clearly indicated that the rate of deformation had an effe~t on the resistance of the connection; rapidly deformed specimens had a greater resistance at a given deflection than those tested slowly. In these tests, the type of fastener, rivet or high strength bolt, had little effect on the moment-rotation characteristics of the connections studied. With respect to the evaluation of specific moment resistance characteristics of connections subjected to rapid loading, this limited pilot study served only to indicate the nature of the resistance function which could be expected for connections of the type te s ted. Also presented in this report is a procedure for evaluating the resistance of a frame with semi-rigid connections as it is loaded into the inelastic range. The method of analysis is such that the resistance characteristics of the connection, as well as that of the members, are taken into consideration. The method is of particular interest from the research standpoint since strain hardening is included.
