ELASTO-PLASTIC DAMPER OPTIMIZATION ROUTINE FOR LATTICE TOWERS BASED ON GENERALIZED RESPONSE SPECTRUM ANALYSIS

摘要

This paper presents a damper design routine for highly indeterminate 3-D structures utilizing computational optimization and response spectrum analysis, which has been extended to incorporate non-proportional damping. This enables a more efficient design process than trial-and-error approaches. An example retrofit of a seismically deficient lattice tower using buckling-restrained braces is presented.
