summary |
Fundamental performance criteria between action effects and relevant performance requirements for serviceability, safety, comfort and functionality are analyzed, assuming randomness of the effect action and both randomness and fuzziness of performance requirements. Randomness due to natural variability of basic variables is handled by commonly used probability theory methods, fuzziness due to vague or imprecise definitions of performance requirements is described by basic tools of the recently developed theory of fuzzy sets. Both types of uncertainties are combined in newly defined fuzzy probabilistic measures of building performance, damage function and fuzzy probability of performance failure, which are then analysed and applied similarly as conventional probabilistic quantities. An illustrative example of optimization of vibration constraints for building structures due to occupancy comfort indicates that commonly considered limiting values for acceleration may be uneconomical. However, theoretical models used to describe fuzzy probabilistic properties of performance requirements need to be reexamined using adequate experimental data. |
