Structural Design with Supplemental Damping
Engineering problem. Structural design of multi-story buildings using a friction damper system.
Structural system. Steel frame with friction dampers
Role and methods. Design management; ETABS design; PERFORM-3D nonlinear time-history analysis
Engineering problem: structural design of multi-story buildings that rely on supplemental energy dissipation.
Methodology: elastic design of the steel system, followed by nonlinear time-history analysis to evaluate the damping devices and global seismic performance.
Tools: ETABS and PERFORM-3D. Role: design management and nonlinear analysis. Technical challenge: coordinating damper demand with member design and detailing. Outcome: a verified structural scheme with supplemental damping.
