摘要
采用一种有限元分析程序(如Ansys,Abaqus,ADINA,MSC,MARC等),模拟钢筋混凝土简支梁受力过程(构件尺寸/材料/支座/加载等信息自定,或引用文献),计算得到其力-位移关系曲线。着重讨论了ANSYS在混凝土构件全过程分析中混凝土材料的单元选择,材料特性,破坏准则等方面。说明只要合理选择单元类型,划分网格等,就能够得出比较准确的非线性特性曲线,从而达到以计算分析代替部分试验目的。
Using a finite element analysis program such as Ansys, Abaqus, ADINA, MSC. MARC, etc. , in simulation of force analysis procedures in reinforced concrete beam in due respect to sizes, materials, load bearing, restraints, etc. required in calculating the force-displacement curve. Ansys software focused on the whole process in reinforced concrete structural analysis in selection of units, material properties, failure criteria, etc. that is a reasonable choice in element type,meshing,able to draw more accurate nonlinear characteristic curve, so as to reduce design costs, shorten the design and analysis duration, increase in the reliability of products and engineering procedures.
