The equilibrium equation considering second-order effect was established by simplifying calculation model. The internal force was corrected with correction coefficient on the basis of the internal force calculation of first-order effect, which embodied affection of second-order effect and analyzed the major factors of affecting second-order effect.
Keywords: bottom story frame structure; second-order effect; simplified calculation method
