有关建筑结构竖向规则性的若干问题讨论

Discussion on several issues concerning the vertical regularity of building structures

建筑结构的规则性判断是抗震设计的前提,也是抗震概念设计的的重要内容。建筑结构的规则性包括平面规则性和竖向规则性。本文对不同标准中竖向不规则的分类和区别进行了归纳总结,并针对质量分布不均匀、连体结构和多塔楼结构的判定、转换构件的数量、错层结构刚度计算、山地建筑等若干问题进行了讨论,讨论结果可为建筑结构的竖向规则性判断提供参考和新思路。

The judgment regularity of building structure is the prerequisite of seismic design and also an important content of seismic conceptual design. The regularity of building structure includes plane regularity and vertical regularity. This paper summarizes the classification and differences of vertical irregularities in different standards, and discussed several issues such as uneven mass distribution, determination of towers linked with connective structure and multi-tower structure with a common podium, the number of transfer components, stiffness calculation of staggered floor structure, and building on the slop. The results of the discussion can provide reference and new ideas for the judgment of vertical regularity of building structures.
