通过 3块 2跨钢纤维混凝土预应力连续叠合板的试验研究 ,分析了预应力连续叠合板塑性内力重分布的特点及影响弯矩调幅的因素 ,认为钢纤维混凝土的弯矩调幅值可适当地提高 ,最后提出了二次受力钢纤维混凝土预应力连续叠合板的弯矩调幅限值公式 ,为这种板的工程应用提供了依据
Through the experimental study of three 2-span steel fiber reinforced concrete prestressed continuous laminated plates, the redistribution characteristics of plastic internal forces and the factors influencing the bending moment modulation of the prestressed continuous laminated plates are analyzed. It is considered that the bending moment modulation value of steel fiber reinforced concrete can be appropriate. In order to improve, finally proposed the bending moment modulation limit formula for the secondary steel fiber reinforced concrete prestressed continuous laminated plates, which provided a basis for the engineering application of the plate.
