Abstract:  In this paper, the frame foundation of centrifugal compressor in a practical project is taken as the prototype, and the parameters of column section size, roof thickness, concrete elastic modulus and column height are analyzed by STAAD-Pro. The effects of the four parameters on the natural frequencies, peak displacements and peak velocities of the frame foundation are given, which can provide reference for the design of this kind of foundation.

Key words: frame foundation, STAAD-Pro, dynamic performance, parametric analysis
