摘　　要：根据经典弹性薄板理论,建立双向密肋楼盖的力学平衡方程,推导出双向密肋楼盖在x、y方向上的抗弯刚度计算公式,并按正交各向异性板,推导出周边简支混合配筋预应力混凝土双向密肋楼盖的弯矩分配公式,计算结果与数值模拟结果和试验结果吻合较好.In this paper, the classical theory of elastic plates is employed to construct a balanced equation of the two-way waffle slab so as to derive the formula of bending rigidity of the two-way waffle slab in the directions and infer the moment distribution formula of four sides waffle slab floor with unbounded prestressed tendons and non-prestressed steel according to the orthotropic slab. With reference to the elastic design method of hyperstatic prestressed concrete structure, examples are given to verify and compare. The calculation results numerical simulation results are consistent with the test results.
