چکیده انگلیسی
The study of cyclic load–deformation relationships of columns in the post-peak region is essential to prevent the collapse of buildings under earthquake excitation. This paper provides an efficient method to predict the pre- and post-peak hysteretic behavior of concrete-filled circular steel tube columns under the combination of constant axial load and cyclic lateral load. A simplified nonlinear fiber element method is used to investigate uni-axial stress and strain relationship of materials in terms of the composite action between the steel tube and the concrete. The accuracy of the proposed computational technique is verified by comparing the results from this technique and experimental results.
