Flexural Demand on Pin-Connected Buckling-Restrained Braces and Design Recommendations

Energy dissipation capacity and earthquake response of steel structures installed with buckling-restrained braces (BRB) were investigated, and a straightforward design procedure to meet a given target displacement was developed. A formulation for…

Although conventional earthquake-resisting structural systems provide adequate life safety when properly designed, they rely on significant structural damage to dissipate the seismic energy. This structural damage and the residual drift that may…

Buckling-restrained braced frames have been shown to exhibit stable energy dissipation behavior under cyclic loading. However, after the buckling-restrained braces yield, the system have a trend of very large story drift and drift concentration.…

The design process of the buckling-restrained braces has been provided in this paper to study on RC frame which is stiffness-insufficient in high seismic region. One simplified design method is proposed in the article in order to satisfy the…

Dual systems can offer an attractive lateral force-resisting solution, combining individual systems in a complementary manner. A displacement based-design (DBD) method is proposed for steel dual systems incorporating moment-resisting frames (MRFs)…

In the company paper, the global drift capacity and demands of a 6-story steel office building adopted with buckling restrained braces (BRBs) have been evaluated. This paper evaluates the seismic performance of the building from a local perspective.…

Buckling-restrained braces (BRBs), which are braces that do not buckle in compression, have recently become popular for use in the primary lateral-force-resisting systems of structures located in high seismic regions of the United States. Although…

Buckling-restrained braces (BRBs) permit exploiting the hysteretic properties of their core material both in tension and compression. However, the global behaviour of the BRB does not fully replicate the local behaviour of the core material and…

The ductile end diaphragm concept developed for regular (i.e., straight) slab-on-girder or deck-truss steel bridge superstructures is expanded to make it applicable to bidirectional earthquake excitation. Buckling restrained braces (BRBs) are used…
