| Abstract: |
| In order to deeply study the load-bearing mechanism of an X-braced structure and reasonably guide engineering design,based on the existing theoretical models,this paper studies the transformation law of the buckling length coefficient of the X-braced structure with out-of-plane supports under typical load patterns,stiffness characteristics,endpoint constraints,and length factor (intersection position).Applied to an actual deepwater jacket structure,the buckling strength of the super-span space X-braced structure with out-of-plane support is analyzed by using the finite element method,and several conclusions are obtained which would provide effective technical support for engineering design. |
