sag tension
2.During the finite element modeling of the bridge,the factors affecting the accuracy of the finite element model are discussed in detail,such as,the geometrical non-linearity of the cable including gravitational sag and initial tension,and the structural orthotropic steel box-girder deck to be equivalent to physical orthotropic deck by using compound material mechanics,and so on.
3.In porch path of the linetype or broken linetype dam Tension Wire Alignment to monitor the level deformation of the dam body is often arranged,The traditional Tension Wire Alignment body uses steel wire of the diameter 0.8~1.2 mm,and generates bigger sag,Floating attachment to float steel wire is used,to reduce the sensibility of the line body.
