  • Description: Spatially incoherent seismic ground motions are represented in both frequency and time domains. The frequency domain representation is employed to obtain closed form solutions for axial and bending stresses that develop in line structures on rigid foundations due to ground motion incoherence. Axial and lateral response of long gravity dams is then investigated including dam-reservoir-foundation interaction. The results indicate that ground motion incoherence can produce significant additional stresses on long dams and other extensive structures. INTRODUCTION Seismic design of engineering structures is usually conducted with input ground motion specified in terms of a response spectrum, a power spectral density function or a single accelerogram.
