摘　　要：以24m×24m正方形大空间楼盖为例,介绍几种常用的井字楼盖布置形式,通过假定计算对其计算结果进行比较,从结构刚度、受力特点、材料用量及施工难易程度等方面说明各种形式的优劣,并对实际工程应用建议优选方案。In this paper,several forms of cross-beam floor slab are introduced. By taking a 24m× 24m large-span Square floor slab as examp le,these structure forms are calculated and the results are compared based on some assumption. Then the paper illustrates the superiorities and inferiorities of these forms from a couple of aspects such as structural stiffness, mechanic properties,material quantity and construction diffi- culty. Finally,some proposals for the applications in the real projects are given.
