What is performance based design approach?

Performance-based design (PBD) is a goal-oriented design approach that specifically addresses performance-related criteria, such as energy use, operating cost, occupant comfort, daylighting, and HVAC size and cost, among others.

What is performance based seismic design?

Performance Based Seismic Design is the seismic design methodology of the future. It allows the design team to work together to determine the appropriate levels of ground motion and Performance Objectives for the building and the nonstructural components in order to meet the owner’s expectations.

What is design based earthquake?

design-basis earthquake (DBE): “That earthquake for which the safety systems are designed to remain functional both during and after the event, thus assuring the ability to shut down and maintain a safe configuration.” design-basis fire: “A fire that is the most severe design-basis accident of this type.

What is PBD analysis?

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 actual earthquake ground motions.

Performance Based Seismic Design is the seismic design methodology of the future. It allows the design team to work together to determine the appropriate levels of ground motion and Performance Objectives for the building and the nonstructural components in order to meet the owner’s expectations.

When to use performance based criteria in earthquake engineering?

For example, force- or stress-based criteria are more appropriate for short period structures, when trying to achieve pre-yield limit state, than displacement-based criteria. Performance-based earthquake engineering (PBEE) is a more encompassing concept that includes design, evaluation and construction engineering [15].

What do you need to know about seismic design?

There is a general agreement among researchers and professionals that future seismic design needs to be based on achieving stated multiple performance objectives. Future seismic design practice will be based on explicit performance criteria that can be quantified, considering multiple performance and hazard levels.

What are the current earthquake code design procedures?

In the current code design procedures, there are uncertainties concerning the seismic demand and seismic capacity of the structure.
