Scope

1.0.1 In order to implement the national laws and regulations on earthquake
prevention and disaster reduction, implement a prevention-oriented policy,
mitigate the seismic damage by seismic-fortifying the petrochemical equipment,
reduce economic loss, this standard is hereby formulated.
1.0.2 This standard is applicable to the seismic design of the petrochemical
horizontal vessel, vertical vessels supported by legs, vertical vessels supported
by lugs, vertical vessels supported by skirt, spherical tanks supported by legs,
vertical cylindrical storage tanks, tubular heater, other steel equipment which
are used in the area where the basic seismic acceleration not exceeding 0.40
g or seismic fortification intensity of 9 degrees or less.
1.0.3 For the petrochemical equipment which is subjected to the seismic design
according to this standard, when it is impacted by the fortification earthquakes
equivalent to the seismic fortification intensity of the area, the body, bracing
member, anchoring structure shall not be damaged.
1.0.4 The design parameters of ground motion or the seismic fortification
intensity shall be determined in accordance with the relevant provisions of the
current national standard “Seismic ground motion parameter zonation map of
China” GB 18306. For the construction site where the seismic safety evaluation
is completed, it shall carry out the seismic fortification according to the approved
design parameters of ground motion or the seismic fortification intensity.
1.0.5 The seismic design of petrochemical steel equipment shall, in addition to
complying with this standard, also comply with the relevant current national
standards.
