Hurricane risk analysis of the residential structures located in Florida

ABSTRACT Florida has distinctively different regions, in terms of population density and hurricane risk. The objective of the article is to understand the characteristics of hurricane loss in different regions of Florida. Two different structures with different components capacities were taken into consideration. The first structure does not meet the current building standards in terms of the high wind performance (‘weak’) and the second structure is built from hurricane proved materials approved by Florida Building Code (‘strong’). In order to bring a new insight into the regional differences in hurricane loss, Exceedance Probability of Loss (EPL) is introduced. The EPL is the probability that the total annual loss will exceed a certain level. The results of this research identified the most vulnerable parts of Florida in terms of the EPL. It has been shown how to combine results of analyses conducted with percentage loss and dollar loss to arrive at a fuller understanding in regional analyses. Finally, the paper also discussed the importance of roof-to-wall connections in preventing the roof uplift.
