摘　　要：运用SAP2000计算厚板转换层的内力,结合实际工程,介绍了转换板结构计算模型选取和荷载施加的方法。结合工程分析了转换板的内力分布的规律,应用有限元分析的方法,对转换层厚板材料强度、局部板厚减薄处理等诸多影响转换层厚板内力的因素作系统的分析研究。分析表明:转换板的内力和位移分布很不均匀;在配筋时不能忽略板内扭矩及轴力的作用;转换板材料强度对板内力及位移影响很小;可以在厚板内力较小的区域作局部减薄处理。In this paper,the internal force of the structural transition layer was analysed by using SAP2000.Combined with the practice engineering project,the method of selecting calculation model and application of the load were introduced.And the distribution law of the internal force of the structural transition layer was further studied.Using finite element method,the factors which influenced the distribution of the inner force were discussed,which include strength of the material and the decrement of the plate thickness in local position.By all these analysis,we can get some useful conclusions.The internal force and displacement of plate transition layer is uneven;torsion and moment in plate transition layer is very important to the reinforcenment;the influence of the material strength of plate transition layer to internal force and displacement is very small;we can reduce part of the plate transition layer＇s thickness where the loading is small.
