Bonjour Aicha tu peux commencer par lire le livre A.K Chopra DYNAMICS OF STRUCTURES, je suis entrain de développer un programme MATLAB qui utilise la méthode Newmark beta pour une structure a plusieurs degrés de liberté
Hello Aicha you can take a look a A.K Chopra book titled DYNAMICS OF STRUCTURES actualley i'm develloping a Newmark Beta methode for calculation MDOF structures in Matlab
I am working on Newmark's method and I am confused because I solved a problem from Prof. Naeem's book for verification of my matlab code but the answers are different.
So I tried the other codes for Newmark's method but each code made a totally different output (For example Ahmeds attached code).
I used your code for the problem but the answer is different with the code that is suggested with Prof. Naeem. So I will be thankfull if you can help me to clarify the problem.
I attached the My matlab code for newmark beta method and also the problem mass, stiffness, damping and load matrix that could be used in your code.
The correct code and solution is also attached which is proposed with professor Naeem.
Please use datas.m for P load to use Ahmeds code because the code requires 2 column for P load (time,value).
In my code, I used P_hat=P(t+dt)+etc. but Prof. Naeem used dP in each step and I don't know the reason.
