Impact Analysis of Tower Number on Automotive Live Load Effect in Suspension Bridge Zhigang QI 1,a, Jun DONG 1,b*, Baoqiang YAO 1,c 1 Beijing Research Center for Engineering Structures and New Materials, Beijing University of Civil Engineering and Architecture, Beijing, 100044, P.R.China a270994241@qq.com,bjdongcg@bucea.edu.cn,c1114665153@qq.com * corresponding author Keywords: suspension bridge, the number of towers, vehicle load, mechanical properties Abstract: As a bridge with a large span, suspension bridge has conspicuous advantage in the current cross-sea engineering.
Introduction With the advancement of science and technology and promotion of the globalization of the world economy, long-span bridges are rapidly developing.
In the construction process of bridge project in the broader straits waters, bridge construction techniques are raised higher requirements to achieve long span capabilities, and for the structural materials, bridge construction, design calculations represent a serious challenge.

Academy of Sciences published "American Competitiveness Initiative" to CPS as an important research project.
We can see, CPS achieves to extend human control in time, space and other aspects; and is the integration calculation of human, machine and material.
So, in China CPS is called “human machine material fusion system” [2].

The commonly accepted advantages of hardware performance and energy economy, achieved due to reduced operating temperatures, are universally positive for all alloys and include lower energy consumption, no handling of liquid metal, longer die life, better yield from the raw material due to lower oxidation, evaporation and fewer other losses related to melt overheating.
In contrast, a lower liquid content within the semisolid slurry reduces shrinkage porosity, which not only improves the material properties, but also allows achieving nearnet shape capabilities.
