Abstract EN
Response sensitivity evaluation is an important element in reliability evaluation and design optimization of structural systems.
It has been widely studied under static and dynamic forcing conditions with deterministic input data.
In this paper, structural response and reliability sensitivities are determined by means of the time domain covariance analysis in both classically and nonclassically damped linear structural systems.
A time integration scheme is proposed for covariance sensitivity.
A modulated, filtered, white noise input process is adopted to model the stochastic nonstationary loads.
The method allows for the evaluation of sensitivity statistics of different quantities of dynamic response with respect to structural parameters.
Finally, numerical examples are presented regarding a multistorey shear frame building.
