Abstract: |
Fragility function is defined as the graphical representation using the curves to express the occurrence of undesirable event as a function of some measure. Fragility Curves has been developed based on results of incremental dynamic analysis. The common form of seismic fragility function is Log-normal Cumulative Distribution function {CDF). The main objective of the study is to develop the best method to find the value of mean and the standard deviation which gives a minimum deviation to that of real Cumulative Probability Density {CPD). For this we have taken data from [1] VULNERABILITY ASSESSMENT OF MRT 205:1994 BUILDING and formulated a program of “Minimum Difference Method” using python. This study shows the reliability of “Minimum Difference Method” in comparisons to the others existing methods. |
