Design Model for Bolted Moment End Plate Connections Using Rectangular Hollow Sections (No. R745)

Abstract

The report presents a model for the determination of the ultimate moment capacity of bolted moment end plate connections utilising rectangular hollow sections and two rows of bolts. The model considers the combined effects of prying action due to flexible end plates and the formation of yield lines in the end plates, enabling the design of the connection with a row of bolts above and below the section. The model has been calibrated and validated using experimental data from an associated test program. The design model constitutes a relatively simple method for predicting the ultimate moment capacity for the particular type bolted moment end plate connection described herein.
