چکیده
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 similar damage mode, namely core unit fracture, whilst short better ductility, but worse dissipation ability than long specimen. A parametric analysis performed based finite element model validated against test result. effects gap friction force between infilled concrete thickness are analyzed. modes multi-wave buckling units exhibited, influence evaluated. Based simulation analysis, CFRP suggested to be used in brace.

Thermal Behavior of Cylindrical Buckling Restrained Braces at Elevated Temperatures
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...

متن کاملEstimation of Hysteretic Damping in Steel Dual Systems with Buckling Restrained Brace and Moment Resisting Frame
Abstract—Nowadays, energy dissipation devices are commonly used in structures. High rate of energy absorption during earthquakes is the benefit of using such devices, which results in damage reduction of structural elements, specifically columns. The hysteretic damping capacity of energy dissipation devices is the key point that it may adversely make analysis and design process complicated. Thi...
متن کاملApplication Procedure for Optimized Placement of Buckling Restrained Braces in Reinforced Concrete Building Structures
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...
متن کاملComparison of Seismic Behavior of Buckling-restrained Braces and Yielding Brace System in Irregular and Regular Steel Frames under Mainshock and Mainshock-Aftershock
Due to low stiffness of braces after yielding, the structures with buckling-restrained braces (BRBs) experience high residual drifts during an earthquake, which can be intensified by aftershocks and causes considerable damages to structures. Also, due to poor distribution of stiffness, this problem is exacerbated for irregular structures. Recently, the yielding brace system (YBS) has been intro...
