W07M03 Multi Degree of Freedom System Modal Orthogonality

[@hariadiyuliantosuyanto813]

love the english pronunciation.. it's easy listening for me

[@muhammadichsan6812]

how can we solve that if the model has dumping ( c ) ?

[@palashjain5318]

Damping ratio (zeta) must be known for the structure type, than damping can be determined knowing mass matrix and stiffness matrix.

@Arif Jamal I would suggest you to have a look at Anil K Chopra's " Dynamics of Structure book " problem no 11.1 on pg no 420. You will get a detailed solution on derivation of Rayleigh Damping Matrix...
