Static Analysis and Simplified Design of Suspension Bridges Having Various Rigidity of Cables

Abstract: Abstract. Increased deformability can be considered as the basic disadvantage of suspension bridges. One of the ways to increase the rigidity of a suspension bridge is to transfer a part of stiffening girder rigidity to a suspension main cable. To give the suspension bridge more stable appearance, the authors propose to use the cables of varying bending stiffness. The main cables can be made of standard section shapes or have a composite section. The object of this work was to study a method for analyzing and … Show more

“…Long-term behavior of the bridges A and B was predicted using MIDAS Civil, a general-purpose finite element analysis program. e validity of the MIDAS Civil has already been confirmed through previous researches [22][23][24]. In general, the prediction of long-term behavior using a finite element analysis is known to have a higher accuracy than that of the methods using a multiplier such as the PCI Bridge Design Manual [18,20], although the design convenience is poor [25][26][27][28].…”

“…In case of concrete box structures, hybrid models composed of one-and two-dimensional elements in a three-dimensional space (e 1 + e 2 ,s 3 ) are also successfully used in numerical analyses as presented in [3,4].…”

“…If the number of compressed elements is quite high, the instability of the structure becomes inevitable, and the solution process diverges. However, when the number of cables in the network becomes high, it is possible to approximate the network by a continuous system leading to analytical methods of analysis [11][12][13][14][15][16][17][18][19][20][21][22][23]; the spacers and the ties are replaced by a continuous inextensible diaphragm. Indeed, because they are presented in the form of exact mathematical expressions, closed form analytical solutions offer many advantages such as: a clear view into how variables, and interactions between variables, affect the result, efficiency, and generates a uniformly distributed action x 1 in the diaphragm.…”
