What is the relationship between the development of civil engineering and the material and the theory? What is the relationship with the needs of society?
Social needs, such as the Qinghai-Tibet Railway Project, China's Great Wall; China's National Palace Museum, and so on
There are three major mechanics in civil engineering; theoretical mechanics; material mechanics; structural mechanics. The discovery of mechanics has also reduced the cost of engineering.
The development of civil engineering depends on the development of materials, the application of new materials, reducing the cost of civil engineering costs. Such as the emergence of light steel structure, the emergence of insulation board building energy has been a breakthrough, and so on.
