| 摘 要： | 本文采用带集中质量杆的剪切振型函数和纵向振型函数取代传统有限条法的位移函数中的匀质梁振型函数。基于所提出的位移函数,推导出平面问题分析公式和联肢剪力墙分析公式,举出两个算例。计算结果表明,与传统有限条法比较,本文方法具有形式简单,通用性强,精度高,编制程序方便等优点。特别在集中荷载作用情况下,本文方法收敛很快,对位移函数中的级数通常仅取头几项,即可得出满意的结果。

| Abstract: | In this paper,shear mode shape functions and longitudinalmode shape functions of an uniform rod carrying concentrated massare adopted to substitute the bending mode shape functions used inthe traditional Finite Strip Method.Formulas for analysing plane pro-blems as well as coupled shear walls are derived and two illustra-tive examples are given.Computational results show that this methodhas the advantages of simpler formulation,wider applicability,high-er accuracy and easier programming.It should be emphasized that insolving problems under concentrated loading this method convergesmuch faster than the traditional Finite Strip Method and only severalterms of the series in the displacement function are needed to obtainsatisfactory results. |
