Thin-shell structures are widely used for cooling towers, chimneys,             storage tanks, pressure vessels, domes and hangers.  However,                   geometrical imperfection of such construction can greatly influence the         buckling and vibrational behaviors, particularly during the earthquake          conditions.  Theoretical methods are developed in this project to study         the non-linear dynamic response behavior of thin-shell structures in            the presence of random initial imperfections which are represented as           zero-mean, Gaussian, homogeneous random processes.  The resulting               random responses are geometrically non-linear depending upon the                magnitude of the load and the root-mean-square value of the initial             imperfections.  The effect of imperfection parameters are studied to            set the tolerance limit for these parameters.
