高层建筑厚板转换层整体分析方法研究

Research of integral analysis methods of thick plate transition layer in high-rise building

在简要总结高层建筑厚板转换层设计方法的基础上,提出了对包括转换层在内的高层建筑进行整体分析的方法,即对结构整体(包括杆件和非杆件)采用实体单元建立有限元模型进行计算,然后按照弹性应力图形进行配筋.并对一个简例进行了详细的分析,说明提出的方法更符合构件的实际受力情况,计算结果精度较好.

On the basis of summarizing the design methods of thick plate transition layer in high_rise buildings, a new method to analyze the whole structure of a high_rise building including the thick plate transition layer is put forward. The first step is to analyze the structure(including the poles and non_poles), then using the solid elements to create the finite element model of the thick plate transition layer, and finally to place steel bars in accordance with stress diagrams. Analysis of a simple example designed by this method indicates that this new method better conforms to the real load conditions; and the precision of the solution is desirable.
