ABSTRACT: Q) d2 [# A7 M" d
The purpose of this thesis is to provide insight into how different geometric parameters such as tower6 E5 ~7 m( V6 G
height, girder depth, and pier dimensions influence the structural behaviour, cost, and feasibility of an

A study of 51 extradosed bridges shows the variability in proportions and use of extradosed bridges,9 i3 I4 s& ^- d
and compares their material quantities and structural characteristics to girder and cable-stayed bridges.9 l0 Q; O7 |* y! P3 Y- I
The strategies and factors that must be considered in the design of an extradosed bridge are discussed.7 `0 k. M" [$ G4 `$ N: k
Two cantilever constructed girder bridges, an extradosed bridge with stiff girder, and an extradosed

behaviour, materials utilisation, and costs of each bridge are compared. Providing stiffness either in the
