Parameters of main components.

Component name	Material	Sectional area (m^2)	Bending moments of inertia (m^4)	Transformed unit weight (kN/m^3)	Modulus of elasticity (MPa)	Coefficient of linear expansion
Upper part of pylon	Concrete; (cu⋅ MPa)	42~63	396~633	26
Middle part of pylon	Concrete; (cu⋅ MPa)	63~102	938~2314	26
Lower part of pylon	Concrete; (cu⋅ MPa)	102~108	2314~2542	26
Main girder	16 Mn steel; ( MPa)	1.47~2.31	4.0~6.5	109.9
CFRP cable (Per)	CFRP tendons ( MPa)	(0.7~1.25)	0	16
Steel cable (Per)	High-strength steel ( MPa)	(0.7~1.25)	0	80

Note. The transformed unit weight of the girder 109.9 includes the weight of stiffening plate; the transformed unit weight of the steel cable 80 includes the weight of protection material.
