Design Model for Bolted Moment End Plate Connections Joining Rectangular Hollow Sections Using Eight Bolts (No. R827)

Abstract

In this report a model for the determination of the serviceability and ultimate moment capacities of bolted moment end plate connections utilising rectangular hollow sections joined with eight bolts is presented. The connection configuration is such that two bolts are located above each of the flanges and beside each of the webs. The model considers the combined effects of prying action due to flexible end plates, the formation of yield lines in the end plates, and failures due to punching shear and beam section failure. The model is calibrated and validated using experimental data from a 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 herein.
