An Improved Stability Design of Steel Cable-Stayed Bridges using Second-Order Effect
2차효과를 고려한 강사장교의 개선된 좌굴해석

Abstract
Practical stability design method of main members of cable-stayed bridges is proposed and discussed through a design example. For this purpose, initial tensions of stay cables and axial forces of main members are firstly determined using initial shaping analysis of bridges under dead loads. And then the effective buckling length using system elastic/inelastic buckling analysis and bending moments considering
