In high seismic areas of the world, dissipation of energy created by earthquakes is vital to keep structures intact and more importantly the conservation of life. Steel structures use braced and moment frames to dissipate this energy through various mechanisms. This paper’s focus is on moment frames, and more specifically on Bolted Flange Plate connections with non-orthogonal geometry. With the complexity of designs increasing due to advancements in research and the want for large open spaces in many structures, moment frames are a popular option because no diagonal bracing members are required. Yet, in AISC 358-10 (AISC, 2010b), only orthogonal moment frame connections are discussed without any mention of how to design for a non-orthogonal connection. Using the finite element software ABAQUS, the effects of non-orthogonal geometry on Bolted Flange Plate connections, both skewed and sloped, were analyzed. Unlike welded moment connections, this connection requires bolts, and therefore two different bolt configurations were also studied, one having the bolt rows staying parallel to the column face and the other having the bolt rows perpendicular to the beam axis. The performance of these finite element models were compared to previous experimental results, based on the orthogonal connection, conducted at the University of California – San Diego. Using the moment-rotation capacity of the connection, distribution of stresses, and location of the plastic hinge, recommendations for the design of non-orthogonal Bolted Flange Plate connections were determined.
