［摘要］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，对结构平面的确定、楼板不连续、楼板的有效宽度、凹凸不规则、组合平面、环形平面和口字形平面等结构规则性相关问题进行了详细的解释说明，并指出平面规则性判断的本质是楼盖的平面刚度是否足够、分块楼板之间连接是否可靠有效。

［关键词］平面规则性判断；凹凸不规则；楼板有效宽度；组合平面

Abstract:The judgment of buildings regularity is the prerequisite of seismic design and also an important content of seismic conceptual design. The regularity of buildings includes plane regularity and vertical regularity. This article is related to the structural regularity such as the determination of the structural plane, the discontinuity of the floor, the effective width of the floor, irregular plane with concave and convex, the composite plane, the circular plane and the hollow plane were explained in detail and it was pointed out that the essence of plane regularity judgment was whether the in-plane stiffness of the slab was sufficient and whether the connection between the partial slabs was reliable and effective.

Keywords:judgment of plane regularity;irregular plane with concave and convex;effective width of floor;composite plane
