Introducing Automation of Performance-Based Design
Performance Based Design (PBD) is a major shift from traditional structural design concepts and represents the future of earthquake engineering. These new procedures help assure that the design will reliably meet a desired level of performance during a given earthquake.
The fundamental component of PBD is nonlinear dynamic analysis where an attempt is made to capture the real behavior of the structure by explicitly modeling and evaluating post-yield ductility and energy dissipation when subjected to earthquake ground motions. ETABS 2015 introduces new special purpose options and algorithms for the practical and efficient application of these procedures
