Structural response to stationary excitation
WebTropical cyclone is a rapidly rotating storm system with severe excitation such as high wind. This severe excitation may change the performance of structures, such as bridges, wharves and wind turbine structures. It is very necessary to monitor this important change. Modal parameters are the ones to reflect the structural instinct behavior. However, many … WebStationary responses of single-and multi-degree-of-freedom structures subjected to stationary input excitations are studied. Using a modal superposition prodedure, closed …

WebNov 7, 2016 · This paper presents the nonlinear response of an earthfill dam subjected to spatially varying ground motion, which includes the wave-passage, incoherence and site response effects. An equivalent linear method is considered in … WebThe response of a linear system to the excitation of a nonstationary random process is studied. The random excitation considered belongs to a general class which may be generated by passing a nonstationary shot noise throuh a linear filter. The behaviors of different filters are discussed. In principle the covariance and the variance functions of an …
WebThis paper proposes an approach for the optimal design of nonlinear energy sinks (NES) installed in structures subjected to stochastic excitation. The response of these nonlinear systems subjected to stationary or non-stationary stochastic excitations has been characterized by the time-history of its covariance matrix.

WebThe response of simple structural systems to stationary random excitation is considered under two criteria of failure. When failure is specified as the crossing of a maximum tolerable threshold by the response, the reliability of a structure is commonly measured by means of response spectra.
