摘　　要：为研究腹板高度、翼缘厚度和钢筋支架间距对一种新型T形肋预应力混凝土叠合板的抗弯性能影响,对8块叠合板抗弯性能进行试验。对比分析了新型叠合板的抗弯刚度、抗弯承载力和破坏特征。研究结果表明:腹板高度、翼缘厚度对新型叠合板的抗弯性能影响较大,而钢筋支架间距的影响相对较小。试验结果与JGJ/T 258—2011《预制带肋底板混凝土叠合楼板技术规程》叠合板计算结果吻合较好。In order to study the influence of the web height,flange thickness and the spacing of steel bars on the flexural behavior of a new type of T-rib prestressed concrete composite slab,8 pieces of composite plates were designed and fabricated. Through experiments,the bending stiffness,bending capacity and failure characteristics of the new type of composite plate were compared and analyzed. The research results showed that the web height and flange thickness had great influence on the bending resistance of the new composite slab,and the influence of the distance between the steel bars was relatively small. The bending stiffness and the bearing capacity of the existing specifications were in good agreement with the experimental results,which could be directly used to guide the engineering design and application.
