By the finite element software ABAQUS, different pipe diameter and circular tubular hollow slabs in different rib spacing are analyzed, with circle tubular hollow slab along the pipe to the cross and to the two direction stiffness and stiffness ratio calculated, the two direction of the elastic modulus designed, as well as shear modulus and poisson's ratio calculation formula. It provides the basis for the theoretical study and design of the cast-in-place concrete hollow slab.Keywords: Circle tubular hollow slab; orthotropy; ratio of rigidity
