Optimization Analysis Model of Self‐Anchored Suspension Bridge [PDF]
Mathematical Problems in Engineering, 2014 The hangers of self‐anchored suspension bridge need to be tensioned suitably during construction. In view of this point, a simplified optimization calculation method of cable force for self‐anchored suspension bridge has been developed based on optimization theories, such as minimum bending energy method, and internal force balanced method, influence ...

The Basic Differential Equations of Self‐Anchored Cable‐Stayed Suspension Bridge [PDF]
Mathematical Problems in Engineering, 2010 The static behavior of self‐anchored cable‐stayed suspension bridge under vertical load is described with the continuum method. Based on the partition generalized variation principle, considering the compression‐bending coupling effect of the main girder and the tower, the large displacement incomplete generalized potential energy functional of three ...

Modified Deflection Theory for Preliminary Design of Self-Anchored Suspension Bridges
The Baltic Journal of Road and Bridge Engineering, 2023 A modified deflection theory is developed for preliminary design of self-anchored suspension bridges. The proposed theory modifies the questionable approach of the existing theory considering the initial fabrication camber and overcomes the limitation ...
