[FEM][有限元][编程][Matlab][Code by myself] FEM Analysis: 2D Euler Beam Element [有限元分析: 2D欧拉梁单元]

（有空和小伙伴一起写写有限元程序）程序作者 ( Author) JiDong Cui (崔济东) 1, XueLong Shen (沈雪龙)2 1.广州容柏生建筑结构设计事务所；2.华南理工大学建筑设计研究院问题描述( Problem Description) 节点1、5处为固定支座，节点4处受到+x方向P=200kN的集中力作用。结构中各杆件采用相同的材料，弹性模量E=30000MPa，梁、柱截面面积分别为0.08m2和0.16m2，梁、柱截面惯性矩分别为0.0128/12 m4和0.0256/12 m4。基于MATLAB编程实现该框架结构的弹性静力分析，所有构件采用欧拉梁单元进行模拟，并将MATLAB的计算结果与SAP2000、midas Gen分析结果进行对比。 MATLAB 编程结果 SAP2000 计算结果 Midas Gen计算结果注释 ( Comments ) 源代码已经收录到新书《有限单元法：编程与软件应用》，详见链接：http://www.jdcui.com/?page_id=9731 ( 如果您发现有错误，欢迎批评指正。邮箱：jidong_cui@163.com …
