| Abstract: The elastic buckling behavior of thin plates changing in width as well as hollow thin section tapered columns are studied using the finite element method. The buckling load is first defined for the case of simply supported trapezoidal plate subjected to uniform compressive stresses. The influence of tapering ratio, aspect ratio and flange width to average web depth ratio on the stability of thin -walled steel members is investigated. The results are compared to those of rectangular plates. The results are represented diagrammatically as function of the buckling coefficient with respect to the different mentioned ratios. The results show that, the buckling coefficient(k) becomes larger as the tapering ratio decreases as well as the flange width to average web depth ratio also decreases. | ||||
