弹性地基上不规则厚板的荷载应力分析

Stress Analysis of Nonregular Thick Plates on Elastic Foundations

弹性地基厚板的荷载应力分析各国学者进行了大量的研究,但主要是针对矩形厚板,对于弹性地基上的不规则厚板(异形厚板)研究尚少,本文对于Winkler地基上的异形厚板提出了曲厚板单元分析法,分析结果表明,本文所述方法具有收敛速度快,计算精度高,用较少的单元就可。获得较好的结果等优点。

In this paper nonregular thick plates on Winkler elastic foundations are studied by the thick plate element analysis method, which is quite valid. The effect of shearing deformation is considered in the curved thick plate elements. Both thick plates and thin plates can be analysed by using the elements. The method in this paper can also be used for regular plates. Key words: elastic foundation, nonregular thick plate. curved thick plate element
