Abstract: Even though 7% of global tropical cyclones are occurring as a medium intensity in the Northern Indian Ocean basin (in Bay of Bengal region) but their effect rendered a huge structural failures. There is a different opinion on the occurrence of cyclones from statistical, demographic and meteorological point of view but the financial loss was gradually increasing during the last decade. The cyclonic vulnerability map of India imparted the occurrence of various high speed wind cyclones in the different locations of the east coastal region. The post cyclonic damage reports revealed that the life line structures were also damaged. It indicated that the risk factor for 100 year design life of the structures was inadequate for safety of structures in coastal areas. Admitting the facts the revised IS 875(part3) 2015 recommended the cyclonic importance factor with 1.15 and 1.30 values for design of structures in coastal region. This recommendation cannot be suggested for hoarding design explicitly in the 2015 code.it is concluded from this analysis the hoardings cannot be treated as temporary structures and the design life must be considered up to a span of 25 years. Ultimately the necessity of k4 factor is highlighted in this paper.
