CUMULATIVE SEISMIC ENERGY DISSIPATION CAPACITY OF TRUSS TOWER STRUCTURES

Seismic retrofit of tower structures by additional buckling restrainer or replacing critical members by buckling restrained braces have been proposed and took into practice by the authors. In this paper, these retrofit methods are studied with the point of view of their cumulative seismic energy dissipation capacities until the fracture of axial members. Past experimental results on various axial members including buckling effects are applied to these verifications.
