无粘结部分预应力混凝土在双向平板无梁楼盖中的应用

Application of Unbonded Partial Prestressed Concrete in two-way Flat Slab with Out Beams

随着国家经济的发展,各方面对结构的需求日益变得丰富多彩,单一的梁板楼盖体系已不能适应需要.普通混凝土双向板无梁楼盖,采用了预应力之后,跨度增加为9m^12m左右.此种结构在国外建造较多,是一种成熟的结构形式.

With the development of the national economy,the demand of the various parties has become more and more various,the single girder slab floor system has been unable to adapt to the need.The span of the unbonded partial prestressed concrete in a two-way flat slab without beams can increase to about9~12m.This kind of structure is built more at abroad,it is a kind of mature structure form.
