【Abstract】 In this paper, the continuous conditions for the displacement between the beam element and the plane stress element are accomplished by introducing a kind of transition element. Furthermore, the combuied finite element model of the members and body is established. The analysis on frame structure is completed. The result shows that the state of superstructure is directly affected by the conditions of basement and foundation. It is necessary to consider the interaction effect of the three parts.更多还原
