Abstract: Shear-acting structural fuses rely on steel plates subjected to in-plane lateral displacements that dissipate energy through shear yielding or may have cutouts that result in shear or flexural yielding of ductile local ...

Abstract: This paper analyzes the ductility and overstrength of steel deck diaphragms and composite concrete on steel deck diaphragms and computes associated diaphragm design force-reduction factors, Rs. First, a database of past ...

Abstract: This paper presents analysis of fracture in structural steel subjected to cyclic loads, which is of paramount importance for evaluating the safety of steel buildings exposed to extreme events such as strong earthquakes. ...

Abstract: Steel moment frames develop large drift capacity and dissipate seismic energy through inelastic deformation in the plastic hinge region near the beam-to-column connection. To discourage fracture in this region, known as ...

Abstract: Elastic buckling and second-order analyses are conducted to establish a more rigorous design procedure for single-level guyed towers, in which the interrelationship between the strength and rigidity requirements of the ...

Abstract: Controlled rocking braced steel frames are seismic lateral-force resisting systems that utilize column-uplifting mechanisms, high-strength post-tensioning, and replaceable energy-dissipating fuses to enhance seismic ...

Abstract: Previously proposed self-centering moment-resisting frames relied on gap opening and closing in the beam–column interface to achieve recentering capability and energy dissipation capacity. The gap-opening mechanism in the ...

Abstract: The self-centering rocking steel-braced frame is a high-performance system that can prevent major structural damage and minimize residual drifts during large earthquakes. It consists of braced steel frames that are designed ...
