@article{(Open Science Index):https://publications.waset.org/pdf/10004981, title = {On the Evaluation of Critical Lateral-Torsional Buckling Loads of Monosymmetric Beam-Columns}, author = {T. Yilmaz and N. Kirac}, country = {}, institution = {}, abstract = {Beam-column elements are defined as structural members subjected to a combination of axial and bending forces. Lateral torsional buckling is one of the major failure modes in which beam-columns that are bent about its strong axis may buckle out of the plane by deflecting laterally and twisting. This study presents a compact closed-form equation that it can be used for calculating critical lateral torsional-buckling load of beam-columns with monosymmetric sections in the presence of a known axial load. Lateral-torsional buckling behavior of beam-columns subjected to constant axial force and various transverse load cases are investigated by using Ritz method in order to establish proposed equation. Lateral-torsional buckling loads calculated by presented formula are compared to finite element model results. ABAQUS software is utilized to generate finite element models of beam-columns. It is found out that lateral-torsional buckling load of beam-columns with monosymmetric sections can be determined by proposed equation and can be safely used in design.}, journal = {International Journal of Civil and Environmental Engineering}, volume = {10}, number = {7}, year = {2016}, pages = {885 - 892}, ee = {https://publications.waset.org/pdf/10004981}, url = {https://publications.waset.org/vol/115}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 115, 2016}, }
