Calculates the response of multi-degree of freedom nonclassically damped linear system subjected to dynamic forces.
Calculates the response of multi-degree of freedom nonclassically damped linear system subjected to dynamic forces (using Newmark's method [1]).
function Result=Newmark_Linear(M,C,K,f,fs)
Input
M:mass matrix (n*n)
C:damping matrix (n*n)
K:stiffness matrix (n*n)
f:external force matrix(n,N)
fs: sampling frequency
where n is the number of degrees of freedom, N is the length of data points of dynamic force
Output:
Result: is a structure consist of
Result.Displacement: Displacement (n*N)
Result.Velocity: Velocity (n*N)
Result.Acceleration: Acceleration (n*N)
