【正文】 Introduction to Civil Engineering Papers Civil Engineering for the development of a key role, first as a material foundation for the civil engineering construction materials, followed by the subsequent development of the design theory and construction technology. Every time a new quality of building materials, civil engineering will be a leapstyle development. People can only rely on the early earth, wood and other natural materials in the construction activities, and later appeared in brick and tile that artificial materials, so that the first human to break the shackles of natural building materials. China in the eleventh century BC in the early Western Zhou Dynasty created the tile. The first brick in the fifth century BC to the third century BC, when the tomb of the Warring States Period. Brick and tile better than the mechanical properties of soil, materials, and easy to manufacture. The brick and tile so that people began to appear widely, to a large number of housing construction and urban flood control project, and so on. This civil engineering technology has been rapid development. Up to 18 to the 19th century, as long as two thousand years, brick and tile has been a major civil engineering construction materials, human civilization has made a great contribution to the even was also widely used in the present. The application of a large number of steel products is the second leap in civil engineering. Seventeen 1970s the use of pig iron, the early nieenth century, the use of wrought iron bridges and the construction of housing, which is a prelude to the emergence of steel. From the beginning of the midnieenth century, metallurgical industry, smelting and rolling out high tensile and pressive strength, ductility, uniformity of the quality of construction steel and then produce highstrength steel wire, steel cables. As a result of the need to adapt to the development of the steel structure have been flourishing. In addition to the application of the original beam, arch structure, the new truss, a framework, the structure of work, cable structures to promote the gradual emergence of the structure of Yan in the form of flowers. From the brick building longspan structures, stone structures, a few meters of wood, steel structure to the development of tens of m
