Example text

The maximum amplitude is delivered by the homogeneous part of the solution (2). And this is only depending on the induced start impulse. At our example it is almost a linear increase of the force. The intention of this research is the development of dynamically optimized floor structures made of coldformed steel C-shaped joists with a deck made of cementitions or wood based plates. The perception of vibrations or the definition of comfort and discomfort of floor vibrations is very subjective. Therefore it is very difficult to define suitable acceptance limits of floor vibrations.

In addition, these higher modes have an impact on adjacent panels not exposed to direct activity. Cable supported footbridge structures often exhibit coupled vibration which can be excessive under certain load patterns (Huang et al, 2005). P. 2009. Dynamic characteristics of steel deck composite floors under human-induced loads, Computers & Structures, Vol 87, 1067–1076. P. J. 2005. Vibration characteristics of shallow suspension bridge with pre-tensioned cables, Engineering Structures, Vol 27 1220–1223.

Our main result is an approximation of the critical angular speeds – in non-dimensional form λ – via the following compact formula where M and N are differential operators, λ plays the role of a loading parameter, and the arbitrary function f characterises the degree of imperfection. The unknown w and the right-hand side f are possibly multi-dimensional vector fields. Equation 1 allows us to formally write w = (M − λN )−1 [f ], and thus it seems reasonable to expect that w → ∞, as λ approaches one of the eigenvalues of the homogeneous generalised eigenproblem (corresponding to f ≡ 0).
