Abstract :
Fragility function of structures is the major requirement of seismic loss estimation which is widely used in the seismic risk management. In this paper, firstly, a comprehensive and simplifies stochastic methods are presented for development of analytical fragility functions. Secondly, the effect of damage threshold uncertainty on fragility functions is estimated. It is shown that the results of the method are almost comparable with the result of previous studies and the effect of uncertainty of damage state on the deviation of fragility function in the lower intensity of ground motion is high which gradually decreases.
