Abstract—The optimal design procedure of buckling restrained braces (BRBs) in reinforced concrete (RC) building structures can provide the distribution of horizontal stiffness of BRBs at each story, which minimizes story drift response of the structure under the constraint of specified total stiffness of BRBs. In this paper, a simple rule is proposed to convert continuous horizontal stiffness o...

The primary focus of this investigation was to analyze sequentially coupled nonlinear thermal stress, using a three-dimensional model. It was meant to shed light on the behavior of Buckling Restraint Brace (BRB) elements with circular cross section, at elevated temperature. Such bracing systems were comprised of a cylindrical steel core encased in a strong concrete-filled steel hollow casing. A...

To rapidly repair the damaged buckling-restrained brace serving as energy absorption member during earthquake, assembled method of wrapping component with FRP cloth is proposed. In this research, a series cyclic tests on six (ABRB) wrapped three kinds FRPs (carbon fiber, glass fiber and basalt fiber) were performed. The tested results show that all specimens excellent hysteretic performance sim...

Passive control systems, such as buckling-restrained braces (BRBs), have emerged efficient tools for seismic response of new and existing structures by imparting strength stiffness to buildings, while providing additional high stable energy dissipation capacity. Systems equipped with BRBs been widely investigated in literature; however, only a deterministic description the BRBs’ properties is t...

Displacement-based methods are recognized as appropriate approaches to reach the goals of performance-based seismic design method. In the direct displacement-based seismic design method, the seismic yield displacement is applied as one of the important design parameters. In this paper, a new relation is suggested to determine the lateral displacement pattern at first yielding of eccentrically b...

In order to realize the buckling-restrained brace (BRB) with high energy absorption performance, it is important prevent premature local bulging failure of restraining part. this study, strength BRB resist part considered be minimum value steel plate considering influence effect filling materials and bearing materials. Local prevented by larger than force acting in out-of-plane direction.
