Introduction Contemporary design of complex mechanical, aeronautical or civil structures requires them to become increasingly lighter, more flexible and yet strong.
To appreciate its significance in the modern engineering arena and its potential for future science and technology, it is appropriate to capture some of the background facts which will help to underline this unique technology.
For an existing engineering structure, it provides vital information on its dynamic behaviour, thus permitting intelligent solutions to vibration problems the structure may be experiencing.
In the last two decades, there have been numerous applications of modal analysis reported in literature covering wide areas of engineering, science and technology.

The ratio optimization of side to main span in low-pylon cable-stayed bridge based on Yudao River Bridge Hongtao Bi 1,a Yan Li2,b 1 Architecture and Civil Engineering, Harbin University of Science and Technology, Harbin, China, 150080 2 School of Transportation Science and Engineering, Harbin Institute of Technology, Harbin, China, 150090 a bihongtao1984@163.com, b liyan2011@hit.edu.cn Keywords: low-pylon cable-stayed bridge; numerical analysis; mechanical properties; ratio of side to main span; Abstract: This paper presents an optimization model for investigating the influence on the ratio of side to main span in low-pylon cable-stayed bridge.
Based on the structural analysis theory of cable-stayed bridge and combined with engineering practical, the optimization model considered that adjusting structural internal force by means of changing the side span length.
Designer can choose the appropriate optimize form according to the specific characteristic of the structure. 3 Engineering examples 3.1 Project Overview.
In engineering practical, we can analysis the influence on the ratio of side to main span about the whole structural force condition in initial operation state.
When the length of side span is 63.6m for the engineering project, on the other hand, when the ratio is 0.53 around, the girder’s force condition is most reasonable.
