高层建筑结构嵌固部位的选取

The Selection of Structural Build-in Parts of High-rise Buildings

高层建筑在进行结构计算分析时,必须首先确定结构的嵌固部位,结构嵌固部位的选取有各种不同情况,如设有地下室,但其层数或多或少;不设地下室,基础形式不同等。如何正确选取结构的嵌固部位,是高层建筑结构计算分析的一个重要环节,它不仅关系到结构中某些构件内力分配的准确性,而且影响结构侧移计算的真实性,以及结构局部的经济性,因此要重视结构嵌固部位的选取。

In high-rise buildings structure analysis,the build-in site of the structure must first be determined;there is different situations for the selection of the build-in parts： being equipped with a basement,but the number of layers being more or less;without a basement,different forms the foundation etc..How to correctly select the site of structural build-in is an important link for calculation analysis of a high-rise building structure,for it is not only related to the accuracy of the internal force distribution of some construction elements in the structure,but also affects the authenticity of calculation of lateral displacement of the structure,as well as economy of the structural local,therefore,the build-in site selection must be attached importance to.
