[动力学][软件][Tool] MDOF_Eigen: MDOF Modal Analysis [多自由度结构模态分析]

分享一个小程序，该程序是之前我在上结构动力学课的时候编制的。程序主要用于进行剪切形框架结构（即，糖葫芦串模型）的模态分析。可以使用该程序求解动力学课本后面的习题。阵型求解使用雅克比迭代法。This program is developed by me in the Structure Dynamics class. It is for modal analysis of shear building (i.e. , flexurally rigid floor beams and slabs ) with lumped mass at each floor.You can use the program to explore eigenvalue problems on you textbook and improve your understanding on free vibration. The program use Jcaobi method for the solution of eigenvalues.
