[REQUEST] Linear time history analysis

[devilmaycry]

Hi guys, anyone has the code to implement this analysis by the newmark's algorithm?!
Note that My mass matrix is consistent.

Linear time history analysis of MDOF structures

Author: Mostafa Tazarv | Size: 349 KB | Format: PDF | Quality: Original preprint | Publisher: Carleton university | Year: 2011

In this function to solve Equation of Motions for different modes, Newmark Linear Method has been used. By modifying inputs F & ft, you can analyze the structute for either earthquake (base-seismic-excitation) or time-dependent load applied to different stories. That's your responsibility to organize phi & omega2 such f1<f2<f3<... Preferred Unit is SI e.g. K(N/mm),M(N.s^2/mm),F(N),g=9810 mm/s^2 & Ag(unitless to g). However, you are free to choose your Unit.

What will happen to the code if we have consistent mass matrices (Mass with off-diagonal terms)???
