Abstract: This paper describes a seismic design procedure for rib-reinforced steel moment connections based on an equivalent strut model. It is shown from the results of finite-element analysis that the force transfer mechanism in ...

Abstract: In this study, the behavior of rectangular hollow-section (RHS) X-joints in compression is investigated, with a focus on the failure mode of chord sidewall failure, which is more likely to occur when the brace-to-chord ...

Abstract: This paper describes the analytical modeling and a seismic design procedure for steel moment connections with a welded straight haunch. Recent test results showed that welding a straight haunch beneath the beam could be a ...

Abstract: The bearing boundary conditions in bolted connections can be classified either as open. when end tear-out is possible, or as closed, when end tear-out is physically impossible. In this study, comprehensive tests of ...

Abstract: In this study, a parallel axial-flexural hinge model capable of representing postyield flexural behavior and considering interaction effects of axial force and moment is proposed for a simplified nonlinear progressive ...

Abstract: An analytical procedure is presented to model the stiffness and strength of dual panel zones; the dual panel zone in a steel column is formed when the conventional beam-to-column connection in steel moment-resisting frames ...

Abstract: Full-width tubular joints, consisting of chord and brace members of the same width (or diameter), have been frequently used in architectural, civil, and offshore structures owing to their higher load resistance compared ...

Abstract: One of the main challenges in applying high strength steel to tubular structures is appropriate design of the welded joints between high strength steel tubular members, i.e., high strength steel tubular joints. Although ...

Abstract: The design axial resistance for circular hollow section (CHS) XX joints is typically calculated as the product of the CHS X joint resistance and a multiplanar factor. A simple function has been used as the multiplanar ...

Abstract: This study explores the possibility of using low yield point steel (LYPS) as the material for seismic retrofitting braces without casing. While buckling restrained brace has commonly been considered for LYPS applications, ...
