S. Benfratello et al., STOCHASTIC RESPONSE OF MDOF WIND-EXCITED STRUCTURES BY MEANS OF VOLTERRA SERIES APPROACH, Journal of wind engineering and industrial aerodynamics, 74-6, 1998, pp. 1135-1145
The role played by the quadratic term of the forcing function in the r
esponse statistics of multi-degree-of-freedom (MDOF) wind-excited line
ar-elastic structures is investigated. This is accomplished by modelin
g the structural response as a Volterra series up to the second order
and neglecting the wind-structure interaction. In order to reduce the
computational effort due to the calculation of a large number of multi
ple integrals, required by the used approach, a recent model of the wi
nd stochastic field is adopted. (C) 1998 Elsevier Science Ltd. AU righ
