The Structure Selection Analysis on the Support Tower of H-type Vertical Axis Wind Turbine Chongshan Baoa , Yong Zhangb School of Civil Engineering, Beijing Jiaotong University, Beijing 100044, China abaochongshan@163.com , bzyz3000@126.com Key words: H-type vertical axis wind turbine, support tower, structure selection Abstract.
Kept the same material, the flexural rigidity of lattice column was larger, it was more suitable for the tower.
On one hand, wind speed exceeded the maximum 35 meters per second at the location of tower, we had to control lateral displacement of the tower reasonably, wind turbine tower was a new type of structure, there was no practical engineering for reference.

A characteristic feature of these materials is a multiphase structure.
Scale of composite materials in dependence on the size of the built-in particles.
Electrodeposition methods for production of nanostructured materials [38].
From the view-point of materials engineering, the information relating to the effect of the electrodeposition process conditions on the composition of composite coatings is very important.
This process determines the properties of the obtained materials.

That is to say, the materials that are needed for production being nearer to the native, the better.
Sample Alternative is to use materials of high sustainability instead of those of low sustainability.
Materials commonly used in construction of general urban public facilities are no longer suitable for Yushu area.
The strong ultraviolet light in Yushu is more likely to shorten the life of materials like plastic.
Among the selected materials, the one that needs to be transported from outside is the lead and aluminum steel mesh.
