Design Model for Bolted Moment End Plate Connections Joining Rectangular Hollow Sections

Abstract

This paper presents a model for the determination of the serviceability and ultimate moment capacities of bolted moment end plate connections utilizing rectangular hollow sections and two rows of bolts. One row of bolts is positioned above the top flange, and the other is positioned symmetrically below the bottom flange. The model considers the combined effects of prying action caused by flexible end plates and the formation of yield lines in the end plates. The model is calibrated and validated using experimental data from an associated test program. The design model constitutes a relatively simple method for predicting the serviceability and ultimate moment capacities for the particular type of bolted moment end plate connection described here. An example is given to illustrate how the design model can be applied to practical connection designs.
