Dear Eng. Members,
My query is "what seismic importance factor shall be used while designing a lethal vessel(column)ground supported. If client specification says that the occupancy category is III then as per ASCE- Table 11-5-1 importance factor is 1.25. Does OC III includes hazardous material?. Furthermore as per para 13.1.1 it should be 1.5 for component containing hazardous material. Is it acceptable to use 1.25 saying that requirement of chapter 13 are not applicable as it is for "non structural components" and not "building structures" or " non building structures"
I express my sincere thanks to all members in advance for your valuable help.
