Experimental Study on Bolted Unstiffened Seat Angle Connections
Publication: Journal of Structural Engineering
Volume 125, Issue 11
Abstract
Seated-beam connections are occasionally used to attach a beam member to a column web or flange, particularly during construction. This paper presents the results of an experimental program that was designed to examine the flexural behavior of bolted, unstiffened seated angle connections. The sensitivity of several critical variables that influence the strength of the connection angle is reviewed. General descriptions of the test procedures and observations are presented, followed by a detailed discussion of the test variables. The test results are compared with corresponding theoretical predictions to asses the accuracy of various analytical models. It was found that seat angle strength is significantly influenced by beam setback, angle thickness, and the bolts that connect the angle to the flange of the supporting beam. Moreover, the strength of the seat angle can be accurately predicted using a plastic hinge based analytical model that reflects the failure mode.
