摘　　要：通过对现行混凝土结构设计规范(GB50010-2002)中叠合式受弯构件的正截面抗裂验算、受力类型分类、一阶段受力叠合板施工阶段临时支撑数量等相关问题进行讨论。对叠合式受弯构件的抗裂验算标准及一阶段和两阶段受力的叠合板类构件的分类方法提出了改进建议,并对几种不同类型底板的一阶段受力叠合板施工时临时支撑的间距提出了具体数值,可供施工时参考。By discussing and analyzing the several problems of the superimposed concrete component of the code for design of concrete structure （GBS0010 -2002）, such as the crack resistance examination of the cross section and inclined section, force-bearing types and the amount of temporary support on mid-span of lamellar slabs bearing force in the first phase, some recommendations to improve the standards for the crack resistance examination and the classification methods of the superimposed bending components are put forward, and the numerical spans of the temporary support for several different types of composite plates in construction are put forward to provide references for construction.

关 键 词：叠合式受弯构件 抗裂验算 受力类型 临时支撑
