Application of Equivalent Static Method and Spectrum Analysis Method in Equipment Seismic Analysis

This paper presents how to use the equivalent static method and the spectrum analysis method to solve the seismic problem of the equipment,and analyzes the advantage and disadvantage of each method by comparing the results of the calculation,validates the feasibility of the two methods in the seismic analysis of pressure vessel,and provides convictive proof for how to choose the appropriate method to solve different seismic problems in the future.
