[提要]  某综合楼在建设初期，将上部18层肋形楼盖改为等厚空心无梁楼盖，2002年5月投入使用。根据新旧两套方案图纸分析了各自的材料耗量，针对新方案并末如有关方推荐资料所述可降低混凝土及钢筋用量，反而有所增加的情况，提出对新设计在计算和构造上的4些意见，以期有助于空心无梁楼盖技术的发展推广。

Two types of floor-plate structure were designed for a same multi-storey building: ordinary slab-beam structure and hollow-cored flat-plate structure. The later as a new technique was adopted in order to save the consumption of concrete and reinforcement. Two types of plate structure's consumption of materials are calculated and it is found out that the hollow-cored flat-plate is not more economical than the slab-beam as expected. Analysis is made and for the improvement and further application of hollow-cored flat-plate structure,some suggestions are proposed.
