Behavior of extended end plate connections

A theoretical investigation of Extended End Plate Connections was performed to study the behavior of the Moment Resistant Connection when designed as per the AISC-LRFD design recommendations. A Finite Element Model of Plate with holes was developed to investigate the distribution of Shear Stresses in the bolts by applying appropriate boundary conditions at the hole region. The study was performed in a logical order starting with the AISC recommendations for behavior of columns and beams connected with a general moment resistant connection. Furthermore, the study was concentrated on the behavior and mechanical properties of high strength bolts and the influence of thread profiles. The basis of design of Extended End Plate Connections as per Krishnamurthy and the simplified design procedure recommended by the AISC was explicated. The significance of pressure distributions at the interface of the beam flange end plate and column flange were studied. The areas of future research were identified and conclusions were drawn based on current AISC Design recommendations.
