Modified equations are then proposed for practical applications on the basis of the flexural capacity for circular concrete filled steel tube members. Under the guidance of “unified theory” and parametric analysis, the simplified practical calculation equations of capacity for CFEST members under eccentric compression are obtained, and mechanical behavior of a series of CFEST members with different section dimensions is conducted using finite element analysis.
