钢筋混凝土井式梁楼盖的挠度非线性分析

Nonlinear deflection analysis of reinforced concrete waffle

以某体育中心井式楼盖为背景,应用有限元软件ANSYS对钢筋混凝土井式梁进行了非线性数值分析,采用实体单元和空间梁单元模型建模,讨论了梁抗弯刚度、混凝土的徐变和边界条件的设置等问题,并对不同模型的挠度解与实测解进行了比较。

In this paper, taken the sports center waffle as example, fern software ANSYS was used to nonlinear numeral analysis reinforced concrete waffle structure. Two different lea model were adopted, including solid element and space beam. The problems as follows were discussed, stiffness of beam resisting bending, concrete creep and displacement boundary conditions. With that, the deflection results in different models were analyzed, and compared with values of measuring.
