Finite Element Analysis of Beam-to-Beam Eccentric End Plate Connections

Abstract

This study presents a broad investigation on eccentric end plates used for beam-to-beam connections by utilizing finite element analysis. This investigation is based on previous experimental work on beam-to-beam connections conducted by a supervisor of this thesis. These connections are vitally essential in the modeling of lightweight structures. For beam to beam joints, there are numerous varieties of joints, including shear plate, clip angle joint, and eccentric end plate, along with T-stub joints, that are frequently used in frame structures. Understanding the rotational attitude of the joints is a fundamental aspect of design. A practical way of evaluating their response is to generate moment-rotation curves and investigate the effects of several parameters graphically. It is concluded that the stiffeners and the end plate are the critical components for failure.
