摘　　要：介绍了现浇混凝土双向密肋空腔楼盖这种新型楼盖结构体系.采用Hoff型夹层板理论[1],即考虑上下表层抗弯刚度的影响而夹心层只承受剪切作用的夹层板理论,导出了现浇混凝土双向密肋空腔楼盖的八阶偏微分方程,给出了矩形平面周边简支条件下微分方程的解析解,并作了算例分析.把有限元模型和拟夹层板法两者的计算结果进行比较,二者吻合较好.The cast-in-place concrete Fabricated Hollow-ribbed floor is a new type floor framing system . This article introduced the cast-in-place concrete Fabricated Hollow-ribbed floor structure, has derived the eighth order partial differential equation and drawn some valuable conclusions. The result of the method of sandwich plate is proved to be in good agreement with the finite element model result.
