- Abstract:
- Considering the effect of non—directional load of cables and suspenders，the principle of the mini—mum potential energy is used to analyse the instability behavior in lateral of cable—stayed arch bridge，and apractical formula to determine the critical load of lateral stability of cable-arch structure is given．The resultshows that the size of cable—plane，level inclination，the size of cable tension，and the anchor position on archof the cable structure and rise-to—span ratio，the bending stiffness of crossbar in arch tangential plane and thequantity of crossbar of arch structure have obvious effect on the lateral stability，but the effect of the bendingstiffness of crossbar in arch radial plane．the torsional stiffness and vertieal bending stiffness of arch rib iSsmall．Considering the effect of non—directional load，cable can improve the lateral stability significantly．
