@article{K._2014, title={Analyses of Steel Bridge Circular Columns using Fiber Model considering Local Buckling}, volume={16}, url={https://ced.petra.ac.id/index.php/civ/article/view/18930}, DOI={10.9744/ced.16.1.1-7}, abstractNote={One of the most concerned problems for analytical estimation of ultimate strength and ductility of steel bridge columns is the consideration of local buckling. Stress-strain curves with softening behavior to include local buckling in fiber model analysis method were proposed by several researchers. However, accuracy of those models is still relatively low. As a consequence, most steel bridge designs have been done using fiber model analysis method without consideration of local buckling. In order to improve the analytical response estimation of steel bridge columns, a fiber model analysis method considering local buckling is proposed in this study. In this method, multi-fiber elements were used to model the local buckling length to simulate local buckling deformation. The proposed method shows good results not only for estimating peak strength but also post-peak strength compared to previous experimental results. However, further research should be directed to improve the accuracy of the deformation modes.}, number={1}, journal={Civil Engineering Dimension}, author={K., Kinoshita,}, year={2014}, month={Mar.}, pages={1-7} }
