Response of Structures to Random Noise
Abstract
The work reported here has been directed along three main avenues. First, a new method has been developed for determination of natural frequencies and associated mode shapes of thin elastic plates and also shallow shells undergoing free, undamped vibration. The method permits consideration of arbitrary boundary conditions along each side of a polygonal plate or polygonal plan-form shell and further offers a comprehensive evaluation of how well the boundary conditions have been satisfied along each edge. Second, the structural reliability of geometrically nonlinear structures subject to stationary random excitation has been investigated by two approaches which have been found to yield satisfactory predictions of reliability. Third, a technique has been developed for prediction of the statistical characteristics of the response of a nonlinear system to nonstationary random excitation.
