Time History Analysis
(OP)
Does anyone know where i could obtain some written detailed information on Time History Analysis for what it is used for?
Thanks,

But, it's like saying po-TATE-toe vs. po-TAT-toe. It's just different ways of saying the same thing.
I think Chopra's book may have an okay expalantion as well. But, I don't know of any book that has a really good or really practical explanation.

To teckert, just think of RHA this way. Normally, when you do a static analysis, you're solving equations of equilibrium such as [K]{x}={F} using standard matrix methods. With RHA, you're solving the equations of *motion*: [M]{x''}+[C}{x'}+[K]{x}={F(t)}. This requires some kind of numerical ordinary differential equation solution technique such as Newmark's. You can look up Newmark's and other methods for solving such equations in Chopra and/or a numerical methods book. The results are functions of time, such a displacement {x} or acceleration {x''}. Can also get force effects such as moments.
That should give you the idea and what it's used for.
