The calculating theory of finite element method of bar system is expounded briefly. Questions of old calculation model are set forth, and a new calculation model is put forward in order to perfect finite element method theory of bar system and fit the calculated result to actual conditions even more.
Keywords: bar system;  finite element method; calculation model; foundation modulus
