Beschreibungen/Notizen
A general framework for multi‐criteria optimal design is presented which is well suited for performance‐based design of structural systems operating in an uncertain dynamic environment. A decision theoretic approach is used which is based on aggregation of preference functions for the multiple, possibly conflicting, design criteria. This allows the designer to trade off these criteria in a controlled manner during the optimization. Reliability‐based design criteria are used to maintain user‐specified levels of structural safety by properly taking into account the uncertainties in the modelling and seismic loads that a structure may experience during its lifetime. Code‐based requirements are also easily incorporated into this optimal design process. The methodology is demonstrated with a simple example involving the design of a three‐storey steel‐frame building for which the ground motion uncertainty is characterized by a probabilistic response spectrum which is developed from available attenuation formulas and seismic hazard models.
