[分享][书籍]《有限单元法-编程与软件应用》书本的所有模型

坚持实干、坚持一线、坚持积累、坚持思考,坚持创新。 前段时间出版的《有限单元法——编程与软件应用》一书是一本有限元MATLAB编程与商业软件应用的基础教程,书中对工程中常用的多种有限单元进行了Matlab编程,并同时在SAP2000、midas Gen或Abaqus中建立算例模型进行分析,与编程结果相互验证。为便于初学者阅读书本,现将书中各章的模型文件(SAP2000,Midas Gen 或 Abaqus)进行整理,并分享给大家。 🙂 🙂 此外,大家也可以在书籍的主页进行模型下载或访问更多关于该书的信息:http://www.jdcui.com/?page_id=9731   微信公众号 ( Wechat Subscription) 欢迎关注 “结构之旅” 微信公众号

[书]PERFORM-3D原理与实例 – 第3章 – 钢筋与混凝土材料的单轴本构关系

材料非线性问题是建筑结构非线性分析中经常涉及到的问题,计算中采用的材料本构模型是否合理,直接影响弹塑性分析结果的精度,进而影响建筑结构的抗震性能评估结果。本章首先对几种典型的钢筋与混凝土材料的单轴本构进行介绍,在此基础上对PERFORM-3D [1,2]中单轴本构的处理进行介绍,并结合PERFORM-3D的规则给出常用钢筋与混凝土材料的单轴本构定义方法。Material nonlinearity problems are very common in nonlinear structural analysis. Whether the nonlinear material model used in numerical calculation is reasonable directly influence the reliability of elastoplastic analysis results, which will further affect the seismic performance evaluation of structures. In this chapter, several typical uniaxial constitutive models of steel and concrete was first introduced. On this basis, uniaxial steel and concrete constitutive models in PERFORM-3D were explained in detail. The contents cover detailed explanation of the ‘YULRX’ backbone and the Hysteresis loops in PERFORM-3D. After that, uniaxial constitutive model properties for several commonly used steel and concrete materials were defined based on the rules of PERFORM-3D.
