Abstract

Problem statement: In this research, four reduced End Plate Moment Connection (EPMC) specimens (T-stubs) are tested to verify the numerical and theoretical methods for preanalysis of the Low Cycle Fatigue (LCF) behavior of a four-bolt extended unstiffened EPMC. Approach: The T-stub specimens are bolted to a support frame and a monotonic load is applied to the stem plate. Yield line theory and the Kennedy method are used to analyze the strength of the end plates and bolts. The Finite Element Model (FEM) and experimental tests are used to verify the theoretical calculations. Results: The theoretical calculations, FEM results and experimental test results show reasonable relationships. Conclusion: The theoretical calculations could be used to predict LCF behavior of specimens.
