本文提出一种分析箱框结构与弹性地基共同工作的新方法,基本内容是:1.箱框的柱脚反力一旦算得,则地基反力及整个结构的内力即可确定;2.箱框作为一个整体与地基共同工作时,其柱脚位移理应为相应点的地基表面位移,而不是取相应的底梁截面的位移;3.直接用梁的挠度曲线的微分方程对底梁与地基作位移协调分析.
This paper presents a new method to analyze the box frame structure and the elastic foundation. The basic content is: 1. Once the column leg reaction force of the box is calculated, the foundation reaction force and the internal force of the entire structure can be determined; When working together as a whole with the foundation, the displacement of the column foot should be the displacement of the foundation surface at the corresponding point, rather than the displacement of the corresponding bottom beam section; 3. The differential equation of the deflection curve of the beam directly is used for the bottom beam and the foundation. Displacement coordination analysis.
