Dissipation Of Earthquake Effects In Steel Structures By Using ADAS Element
Öz
Lateral displacement control of structures and preventing the damage of structural and non-structural elements are important for working and living comfort. Passive energy dissipation (PED) devices, which dissipate the energy applied by seismic loads and reduce the structural damages due to giving additional damping and stiffness to the structures, are one of the control mechanisms. In this study seismic response of the structures are investigated by using ADAS (Added Damping And Stiffness) element which is one of the PED devices. 7, 10 and 15 stories steel frames are analyzed for two different earthquake acceleration records. Top story displacements and base shear forces of frames used ADAS element have decreased compared to those of frames that are not used ADAS element.
