高层建筑厚板转换层的结构分析目前仍未得到很好的解决。本文基于Ｍｉｎｄｌｉｎ假设，建立了中厚板八节点等参单元，很好地满足了厚板转换层结构分析的需要。本文应用计算机辅助设计理论及科学计算可视化技术，编制了相应的软件包，在工程应用中取得了满意的结果。该软件包仅需极少量的几何及荷载信息，便可自动生成有限元分析所需的信息。原始数据及生成的有限元网格均用图形显示，以便校核。对计算结果可绘制任一剖面上的位移、内力曲线及整板的位移。内力等值线。
The structural analysis of the high-rise building slab conversion layer is still not well resolved. Based on the Mindlin hypothesis, this paper establishes an eight-node isoparametric element in the plate, which satisfies the needs of structural analysis of the slab conversion layer. In this paper, computer-aided design theory and scientific computation visualization technology are applied to compile corresponding software packages, and satisfactory results are obtained in engineering applications. The software package requires only a minimal amount of geometry and loading information to automatically generate the information needed for finite element analysis. The raw data and the generated finite element meshes are graphically displayed for checking. The calculation results can be plotted on any section of the displacement, internal force curve and the entire plate displacement. Internal force contour.
