Seismic stability of buckling-restrained braced frames
Buckling Restrained Braced Frames (BRBFs) are widely used as a seismic force-resisting system due to their advantageous properties for ductility and energy dissipation. However, because of the modest overstrength and relatively low post-yielding stiffness, BRBFs subjected to seismic loading may be …

Effect of Beam Splicing on Seismic Response of Buckling-Restrained Braced Frames
The deformation capacity of typical buckling-restrained braced frames (BRBFs) is limited by the rotation capacity of connecting regions. The rotation capacity of the connection region is limited by fracture of the gusset welds and yielding in the beams and columns. A different connection detail …

A Comparison of Optimized Nonlinear Time History Analysis and the Equivalent Lateral Forces Method for Brace Design
… the development of a design procedure for buckling-restrained braced frames (BRBF's). This procedure uses nonlinear time history analysis and a formal optimization algorithm. The time history analysis includes an elasto-plastic model for the braces. The optimization algorithm is a genetic …

Performance-Based Analysis of a Reinforced Concrete Shear Wall Building
… similar studies which used steel special moment frames, special concentric braced frames, and buckling restrained braced frames for their primary lateral systems. The results showcase expected seismic performance levels for a commercial office building designed in a high seismicity region with …

Weighing the Financial and Sustainable Benefits of High Performance Structures in Seismically Active Regions
… system of a four-story structure utilizing buckling restrained braced frames was designed to meet code-level requirements per the American Society of Civil Engineers’ <em>Minimum Design Loads for Buildings and Other Structures </em>(ASCE 7-05) and again to meet the immediate occupancy …

Hybrid Steel Frames
… two new structural steel systems: hybrid Buckling Restrained Braced Frames (BRBF) and hybrid steel Moment Frames (MF). The "hybrid" term for the BRBF system comes from the use of different steel material including carbon steel (A36), high-performance steel (HPS) and low yield point (LYP) …

Computational and Experimental Study on the Behavior of Diaphragms in Steel Buildings
… of two parts, i.e., a vertical LFRS such as braced frames or shear walls, and a horizontal LFRS with diaphragms playing a crucial role. There are various types of floor and roof diaphragms in steel buildings, such as concrete-filled steel deck diaphragms for the floor system and bare steel …
