Existing Reinforced Concrete (RC) buildings designed according to outdated regulations and codes may lack seismic performance (strength, stiffness, and ductility) to meet [...]

Buckling-restrained braces (BRBs), developed in the late 1980’s in Japan, are now widely used as ductile seismic-resistant and energy dissipating structural members in [...]

Recently, there have been concerns of the risk of fracture at the beam-ends of existing steel building frames during the long period and long duration motion of the Nanka [...]

Buckling restrained braces (BRB) are a popular seismic lateral force resisting system. While some tests indicate excellent performance of BRBs, studies in recent years ha [...]

This paper describes a multipurpose setup system called “test bed” for large shaking table tests. The test bed comprises multi-story box-trusses with concrete mass of [...]

A new type of seismic isolation system – called the core-suspended isolation system (CSI) – has been recently developed and implementation completed in the first buil [...]

Buckling Restrained Braces (BRBs) are commonly used as ductile bracing elements in seismic zones. A key limit state governing the BRB behavior is overall flexural bucklin [...]
