Abstract Tall buildings have unique seismic challenges, particularly the P-delta effect. This can cause an increase in loads on certain parts of structure, leading to potential instability or collapse. The solution is use buckling restrained bracing (BRB) systems, which improve lateral strength structure and control present study aimed determine effectiveness various brace configurations reduci...

the most conventional method for lateral bracing of steel frames is using diagonal and x steel braces. in conventional method, braces of frame emplace in one bay or more, relative to structural requirement, from first to last story without displace the braces emplacement on height as columnar form. this pattern is a preliminary and simplest bracing template that the generally codes present base...

Concentrically braced frames (CBFs), designed using the conventional linear elastic method without seismic proportioning and detailing requirements, are referred to as Conventional CBFs (CCBFs) in this study. They widely used moderate low areas North America due ease of design economy. Without a code specified dedicated fuse member dissipate earthquake induced energy, or prescribed yield/failur...
