What are the functions of mechanics and structure in civil engineering? What is the close relationship between mechanics and structure?

Mechanics is the foundation of civil engineering, and structure is the embodiment and expression of mechanics. Whether a structure is reasonable and can be realized must be tested by mechanical analysis, and the success of the structure also proves the correctness of the mechanical analysis.

The dead weight of the structure and the external force exerted on the structure have long been called loads, such as dead load, floor live load, vehicle load, snow load, wind load, crane load, gray load of house area, wave load and so on. In fact, action and load can be used as synonyms, but load has been used to refer to direct action.

structure

In addition to the deformation caused by external force, the structure can also be indirectly constrained by some reasons (such as the expansion or contraction of structural materials caused by concrete shrinkage, steel bar welding, atmospheric temperature change, etc.). , and the deformation indirectly caused by the constraints of structural supports or nodes) and external deformation (deformation caused by the stress of the structure due to uneven settlement of foundation, earthquake and other reasons).
