Static Experiment and Finite Element Analysis of a Multitower Cable-Stayed Bridge with a New Stiffening System

Table 7

The displacement at the important points by loading on sidespan (mm).

Model	Maximum deflection of midspan		Maximum deflection of sidespan		Horizontal displacement of midtower top	Horizontal displacement of side tower top
	Left midspan	Right midspan	Left sidespan	Right sidespan		Left tower	Right tower
1	2.35	−1.01	−3.04	0.26	1.01	1.21	1.13
2	1.97	−0.45	−2.66	0.12	0.87	0.91	0.83
3	1.88	−0.38	−2.54	0.10	0.79	0.98	0.89
4	2.11	−0.99	−2.64	0.23	0.97	1.13	1.02
5	0.85	−0.21	−1.29	0.04	0.07	0.89	0.77

Note. Upward displacement of midspan is positive and downward displacement of midspan is negative. Left horizontal displacement of tower top is positive and right horizontal displacement of tower top is negative.
