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...

Passively damped bracing systems in steel frames, in which the conventional materials of the joint are replaced by high damping viscoelastic materials, have the potential of being effective practical means for passive vibration control of dynamically loaded civil engineering structures. However, this potential can be realized only if the associated structural penalties are reduced within accept...

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...
