Abstract: This paper summarizes the seismic damage characteristics of petrochemical static equipment. It analyzes and compares GB/T 50761—2018 Standard for seismic design of petrochemical steel equipment from such aspects as seismic fortification and importance category, earthquake action, load combination and allowable stress, seismic system design and construction measures. The paper elaborates the reasons for the preparation of the corresponding clauses of the standard. Meanwhile, with reference to the seismic design codes at home and abroad, it presents an outlook on the development of GB/T 50761 from the aspects of ground motion, multi-level performance seismic design and limit state method and so forth.

Key words: GB/T 50761, petrochemical static equipment, seismic design
