Seismic assessment and rehabilitation
Existing Building Seismic Assessment
Engineering problem. Seismic assessment and rehabilitation of existing buildings using nonlinear analysis.
Structural system. Existing building structural systems
Role and methods. Assessment; rehabilitation; PERFORM-3D nonlinear analysis
Engineering problem: seismic assessment of existing buildings and development of rehabilitation measures.
Methodology: three-dimensional modeling, nonlinear pushover and time-history analysis, and comparison of demand with acceptance criteria used in seismic rehabilitation practice.
Tools: PERFORM-3D. Role: structural assessment and rehabilitation engineering. Outcome: performance evaluation and rehabilitation recommendations without disclosing project identity.
