Abstract: The postbuckling behavior of seismic-resistant braces in steel frames under a cyclic axial force is often evaluated by time–history analyses; however, brace fracture is seldom considered. The authors previously proposed a ...

Abstract: Tubular-section members are commonly used as seismic-resistant braces because they have a higher moment of inertia than open cross sections of equivalent area. However, the cumulative cyclic deformation capacity of tubular ...

Abstract: The friction behavior of mortar–polymer–steel debonding interfaces was experimentally investigated to support numerical simulation of buckling-restrained braces (BRBs). Characteristic contact and slip demands were developed ...

Abstract: Recently, passive vibration control design has gained popularity. The aim of this design is to absorb most of the seismic energy by using additional dampers while maintaining the elasticity of the main structure. Buckling ...

Abstract: This paper introduces a grid-purlin system, which was composed of secondary rectangular-hollow-section grids welded onto the top flange of I-shaped beams of moment frames. The welded grid-purlin itself may play a role of ...
