Performance assessment of special concentrically-braced frames in moderate seismic regions
Steel concentrically-braced frames (CBFs) are widely used lateral force resisting systems with high strength, stiffness, and material efficiency. Special concentrically-braced frame (SCBF) systems are a type of CBF commonly used in high seismic regions because they are designed to permit large …

Assessment of seismic design provisions for multi-tiered ordinary concentrically braced frames
Multi-tiered braced frames (MT-BFs) are commonly used as lateral force resisting systems in tall single-story buildings such as performing arts and sports centers, industrial warehouses, and airplane hangars. Horizontal members (struts) are used to divide the tall single-story into several bracing …

Beam-column connection flexural behavior and seismic collapse performance of concentrically braced frames
… to improve the seismic collapse performance of concentrically braced frames. Previous experimental and field observations demonstrated that reserve lateral force-resisting capacity due to the flexural strength of connections outside the primary lateral force-resisting system of steel frames can …

Seismic Rehabilitation of Steel Concentrically Braced Frames Vulnerable to Soft-Story Failure Through Implementation of Rocking Cores
<p>Recent research reports that steel Concentrically Braced Frames (CBFs) (even the code-compliant ones) may be susceptible to soft-story failures during strong earthquakes. Such a failure mode causes catastrophic outcomes and should be definitely avoided in practice. This thesis focuses on …

Evaluation of Strength Reduction Factor for Concentrically Braced Frames Based on Nonlinear Single Degree-of-Freedom Systems
… conducted using a FEM single degree-of-freedom Concentrically Braced Frame (CBF) under incremental dynamic analysis over a suite of ground motions. Parameters of the study include brace slenderness, fundamental frequency, increment resolution, FEM mesh refinement, effects of leaning columns, and …

Inelastic behavior and seismic collapse prevention performance of low-ductility steel braced frames
… and in some instances nonexistent. Ordinary concentrically-braced frames (OCBFs) have requirements that are intended to provide a small level of ductility, and steel SFRSs designed with a response modification factor R = 3 have no specific seismic requirements. Rather than relying on …
