Abstract: This paper introduces the common calculation methods for exposed steel column base plate in petrochemical industry. In order to minimize the thickness of steel column base plate, finite element analysis is performed by using the same plate edge support assumptions as the classical design approach for areas subjected to pressure based on the analysis of the characteristics of column base plate and the research on design methods, and the calculation method, formulas, design limit values and design considerations for areas subjected to the tensile load as well as the pressure are presented. Verification of the base plate under various loading conditions indicates that the calculation method and formulas proposed in this paper are safe and reliable, and are easy to use for engineers.

Key words: exposed steel column base, base plate, corner area, anchor bolt
