［摘要］多层大跨度公共建筑的混凝土结构体系的关键是楼盖，传统的楼盖做法是混凝土和预应力混凝土框架结构平面力系。在混凝土空腹夹层板结构的基础上，提出正六边形平面的多层大跨度混凝土蜂窝型空腹夹层板楼盖，以满足公共建筑楼盖平面形式多样化的要求。介绍了新结构体系的组成、构造、力学特性，并与传统结构体系进行对比分析，结果表明，在正六边形平面中，新结构的力学模型为一块考虑剪切变形的类似圆形平面的夹芯板，其经济指标优于传统结构。

Abstract:The key  of concrete structure system in multilayer long-span public buildings is the floor system. Traditional floor systems are concrete and prestressed concrete structures, which are plane force systems. Based on the  concrete open-web sandwich plate structure, the concrete honeycomb open-web sandwich plate was proposed in order to meet the requirements of the diversification of the flat form of the public buildings. The composition, structure and mechanical properties of the new structure system were introduced, and then compared with the traditional structure system. The results show that in regular hexagon plane, the mechanical model of the new structure is a sandwich plate with similar circular shape considering shear deformation, and its economic index is better than traditional structure.

Keywords:regular hexagon; multistory long-span; floor structure; concrete structure; honeycomb open-web sandwich plate
