Abstract
After the Northridge earthquake, special concentrically braced frames (SCBF) have recently been introduced; further studies conducted to eliminate their shortcomings, design flaws and implementation of connector plates and their vague behavior after seismic load cycles led to development of a new CBF called buckling restrained braced frame (BRBF). In these braces, the steel core which is enclosed within steel profile filled by special concrete encloses the core completely and prevents buckling and increased critical load until compressive axial capacity is only restrained by steel yield tension. This allows the steel core resist against axial forces using entire resistance of the steel as long as casing resists against tensile buckling. As a result, braces act as structural fuse and lead to plastic behaviors, beams, and columns remain elastic in the seismic process. This study builds, tests and numerically models a buckling restrained brace to evaluate sample adequacy to meet requirements of the AISC 341-16 code.
