[论文][Paper]基于试验的ABAQUS混凝土塑性损伤参数取值方法(Determination of Damage Parameter of ABAQUS CDP Model Based on Test Data)

在ABAQUS的混凝土塑性损伤本构中,塑性损伤参数是影响钢筋混凝土构件行为的重要参数,其取值不仅影响卸载或反向加载的刚度,且直接对构件应变成分有很大影响.对国内外多组混凝土单轴往复压、拉试验数据进行统计分析及数据拟合,提出了一种新的塑性损伤参数的取值方法.与其他方法的比较及数值试验均表明,该方法能较准确地反映真实的混凝土退化特性,并且相对于其他损伤参数取值方法形式更为简洁,便于使用.

[PERFORM-3D][Tool] RC剪力墙纤维截面工具 [Shear Wall,Inelastic Fiber Section]

针对PERFORM-3D软件的RC剪力墙纤维截面剖分小工具。程序通过导入文本参数(.csv),直接生成纤维截面的参数,并导出PERFORM-3D需要的二进制文件(.PF3CMP)。This program is used for the data input of the “Inelastic Fiber Shear Wall Section” in PERFORM-3D. Through the import of section properties in text format (.csv), the program can generate the fiber section properties automatically. And then, the program export the binary data input file (.PF3CMP) for “Inelastic Fiber Shear Wall Section” which PERFORM-3D can then read to complete the fiber section definition.

[PERFORM-3D][Tool] 矩形RC柱纤维截面工具 [Column,Inelastic Fiber Section – RC Rectangular Section]

针对PERFORM-3D软件的RC矩形柱纤维截面剖分小工具。程序通过导入文本参数(.csv),直接生成纤维截面的参数,并导出PERFORM-3D需要的二进制文件(.PF3CMP)。Through the import of section properties in text format (.csv), the program can generate the fiber section properties automatically. And then, the program export the binary data input file (.PF3CMP) for “Inelastic Fiber Column Section” which PERFORM-3D can then read to complete the fiber section definition.
