[有限元][编程][日记] PFSAP: 平面框架弹性静力分析程序

旧博客(2013年)中的日记,当初学习有限元时候做的笔记,现转移到 www.jdcui.com 备份!!! 最近一段时间决定开始认真地去学有限元了,基本的理论应该认真地去学好,很重要,没有理论为前提,研究很难深入下去,且根本无法去应用,更别说把程序当成工具了,简直就是被程序玩弄。所以,要多看书,多思考,多动手, 学习基本理论。 为此,初学FEM的过程中,写了个十分十分简单的小程序:PFSAP,即平面框架结构分析程序。前两天刚刚完成。PFSAP包括简单的前后处理,通过图形操作建立模型,可以进行一般的平面桁架、刚架、组合结构的静力分析,类似结构力学求解器,当然功能简单很多。做这个东西主要是想体验一下。以下是程序界面: 下面测试一个简单的桁架例子,参考教材 — 同济大学朱慈勉老师编的《结构力学》下册,例8-1桁架例子。 (1)建立模型,指定支座,施加节点荷载。 (2)分析,查看变形图 (3)查看轴力图 (3)查看支座反力   记录一下,改天再详细测试一下其他的例子 😯 …… 小结:学习有限元,动手实践很重要,实践包括用通用的有限元程序去操作,也包括自己编些小程序来体验;因为公式都是那样,不同的书虽然讲得有深有浅,但是当你看多了以后,看懂了以后,再继续看下去单纯从书面来获得的东西就越来越少了,这时候如果能动手实践一下,那么理解会更加深刻,也能够明白里面的一些比较关键的东西。所以我认为,学任何东西都有下面一个过程:听懂->看懂->做出来->创造。这几个过程都叫“懂”了,但是懂的深度是逐渐加深的,当然要想向着更高的高度发展,要付出越来越多的精力和努力。 附上【Video】 微信公众号 ( Wechat Subscription) 欢迎关注 “结构之旅” 微信公众号

[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.
