Abstract:

The basic concept of structural mechanics is very important in structural design. Based on the basic theory of structural static equilibrium equation and the principle of finite element analysis, this paper mainly discusses stiffness and strength, the most important structural concepts. In structural analysis, selection of structural system, seismic analysis and the design of foundations, the basic concept of structural mechanics can be widely used to guide the structural design and optimization.
