In structural elements, with the variation angle of horizontal orthogonal accelerogram components, the response to the relation between the principal axes of the building will vary. In this paper, a steel building that is regular in plan and height, using seven acceleration records, is analyzed by nonlinear dynamic analysis and the critical angle and relation variation responses are calculated. Results indicated the critical angle is different with varying acceleration records. In this study, the increase in the intensity ground motion and nonlinear behavior in the structural elements is also investigated. Results indicated that critical angle and increase relation responses vary with an increase in the intensity ground motion.
