Evaluation of Seismic Behavior and Select Optimal Situation of Cylindrical Frictional Dampers in Steel Structures

In this investigation, seismic response of steel structures utilizing Cylindrical Frictional Dampers (CFD) is studied. CFD is an innovative frictional damper which comprises two principal elements, the shaft and the hollow cylinder. These two elements are assembled such that one is shrink-fitted ins...
