Bolted moment end-plate connections are extremely popular in the metal building industry due to economics and construction ease, yet have proven to be quite complicated from the analysis and design standpoint. Past research has shown that the design of these connections is controlled by either the strength of the end-plate, determined by yield-line analysis, or the strength of the bolts, determined by the semi-empirical Kennedy method. The calculations involved in the Kennedy bolt analysis incorporate prying action, yet are complex and extensive.
This study presents a simplified method for determining the ultimate strength of moment end-plate connections. Classic yield-line analysis is used to determine the connection capacity based on end-plate strength, and a simplified version of the Kennedy method is used to predict the connection capacity based on bolt strength with prying action. Assumptions are made that substantially reduce the calculations involved in the bolt analysis. The simplified design procedure is verified by comparison with the results of 52 previously conducted full-scale connection tests. Design recommendations are made and examples presented. / Master of Science
