摘要
A statistical approach for time-variant system-reliability problems has been developed and investigated in this study. The basic proposal is to use a response surface, characterised by a statistical model of the mixed type, to represent the capacity part in an analytical limit state function. The fragility of the system is then calculated by SORM analysis, with the constructed empirical limit state function as input. The developed method has been applied to a reinforced concrete frame: investigations have been carried out to check the stability and accuracy of the suggested procedure.
