|Abstract:||The effects of various types of stiffeners on the connection behaviour between box-column to I-beams has been studied both experimentally and analytically using the finite element method. The external T-stiffener has been found to provide the most suitable form of stiffening in terms of stiffness, strength, ductility and ease in fabrication which are the basic criteria for a good moment connection. A simple design method to determine the dimensions of the external T-stiffener for both the two-wat and four-way connections has been proposed. A method for predicting the moment-rotation characteristic of the connection using a least-square curve-fitting procedure is also described. Finally, two four-way full-scale specimens designed in accordance with the design guidelines were tested to failure. The experimental results as well as results from finite element analysis show the validity of both the design guidelines and the proposed moment-rotation functions. © 1993.|
