摘要
本文采用八结点六面体等参元,用空间非线性有限元方法,分析了钢筋混凝土 T 梁和Π梁的受力情况,其中考虑了混凝土开裂及空间非线性的材料本构关系和破坏准则等因素。用 FORTRAN 语言编写了电算程序,并用本程序详细地分析了Π梁顶板宽度和厚度的变化对结构受力的影响。
In this paper,the R.C.T and beams are analysed by three-dimensionalnonlinear finite element method and eight point hexahedron isoparametric ele-ments are used.The effects of concrete cracking,space nonlinear materialconstitutive relation and failure criteria are considered.Computational pro-gram is compiled in FORTRAN language and the effects of change of widthand thickness of beam flange are analysed.
