The single plate framing connections are those where a plate is shop welded to the support element, either a beam or a column, and field bolted to the web of the supported beam. Usually, a single plate connection is assumed to be flexible but, actually, it is semi-rigid. This connection type was studied mainly by Richard, and his tests indicated that a significant moment can be developed at the end of the supported beam. Nonlinear finite element analyses of single plate framing connections are carried out. The assumed Load-Deformation behaviorof single bolt connections was based on the tests made by Richard. Shell and beam elements are used, suitable for plastic analyses with large displacements. Nonlinear spring elements are associated with the individual Load-Deformation behavior of the bolts. This research is extended to the case of beams connected to column webs. All the results are presented as Moment-Rotation curves and relevant ultimate strengths.
