Introduction,te 60’s, mainly because of the availability of high-speed computers and general purpose finite-element programs. Numerical (finite-element) and experimental modal analysis have become standard engineering tools.

Random Variables, times, assume we obtained the following sequence of results: . The outcome . occured .. = 21 times while . occured .. = 29 times. The relative frequencies are respectively . In fact, we know that if the number n of repetitions of the experiment increases indefinitely, the relative frequencies tend

Random Response of Multi Degree of Freedom Systems, structural displacements. Equation (6.1) expresses the equilibrium between the external, elastic, inertia and damping forces. For lack of better knowledge, the damping is often assumed viscous. The matrices ., . and . are symmetric semi positive definite. . and . result from the discre
