New expressions to estimate damping in direct displacement baseddesign for special concentrically-braced frames [PDF]
Numerical Methods in Civil Engineering, 2015 Different expressions have been developed to determine damping of structures based on various hysteretic models and ductility levels. Since Slenderness ratio is an important parameter on the hysteretic behavior of special concentrically- braced frames ...
