ANALYSING THE WORK OF ELASTIC FOUNDATION BEAM IN COORDINATION WITH FRAME STRUCTURE BY USING THE COUPLING THEOREM OF B. E.M. AND F. E. M

    摘要
  • 摘要: 本文首先利用功的互等定理导出了弹性地基梁的四组基本解,建立了求解弹性地基梁的边界方程,进而由边界元及有限元的耦合理论对弹性地基梁及上部框架结构的协同工作进行了一系列的探讨。

     

    Abstract: This paper deduces four groups of fundamental solution to the elastic foundation beam by using the work reciprocal theorem, sets up the boundary simultaneous equations regarding the elastic foundation beam, and a series of approach to the work of elastic foundation beam in coordination with its frame structure is made by using the coupling theorem of boundary element method and finite element method.
