【摘要】 本文主要研究现浇混凝土圆管式空心板的正交各向异性特性。通过ABAQUS有限元软件对不同管径和不同肋间距的圆管式空心楼板进行分析,得到了圆管式空心楼板顺管向和横管向两个方向的刚度及刚度比,给出了两个方向的弹性模量,剪切模量和泊松比的计算公式,为现浇混凝土空心板的理论研究和设计提供了依据。更多还原

【Abstract】 The cast-in-situ concrete hollow round tube plate of the orthogonal anisotropy was studied.By the finite element software ABAQUS,different pipe diameter and circular tubular hollow slabs in different rib spacing were 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.更多还原
