摘要
由若干块单向预应力底板拼合,并浇筑后浇层形成的双向受力叠合板,其现有的设计计算方法存在不合理之处。通过对7.3m×6.9m的四边简支单向预应力双向叠合板进行静力加载试验,并通过理论分析,提出按刚度分配原则设计单向预应力双向受力叠合板的方法,与实际受力相符,具有较好的经济性,且较为实用。
The existing design and calculation method of the two-way stressed composite slab formed by the base plate assembled by several unidirectional prestressed bottom plates and the post-pouring layer is not reasonable.In this paper,the static loading test of 7.3m×6.9m unidirectional prestressed bi-directional composite slab with four sides simply supported is laid out.According to the results of experimental analysis and theoretical analysis,the method of designing unidirectional prestressed two-way stressed composite slab in the light of the principle of stiffness distribution is proposed.The proposed design method is consistent with the actual stress and has good economy and practicability.
