| 摘 要： | 通过引入过渡单元，实现了梁单元与平面应力（或应变）单元的位移连续条件，建立了杆系与实体有机联接的有限元组合模型，并对框架进行了计算分析。计算结果表明：地基及基础条件直接影响上部结构的受力状态，考虑三部分的联合作用是十分必要的。

| 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. |
