Foundation Vibration Analysis Using Simple Physical Models

KEY BENEFIT: The rigorous methods used to model unbounded soil in large, complex projects are often not really appropriate for use in smaller, less critical projects. However, simple physical models are useful for the vast majority of foundation projects and they easily fit the budget and available time and require no sophisticated computer code. Offering a strength-of-materials approach to foundation dynamics, this volume shows how to use such simple physical models (cones, lumped-parameter models, and prescribed wave patterns in the horizontal plane) for analysis of foundation vibration problems that result from earthquakes, machine foundation, explosions, winds, and ocean waves on offshore platforms. KEY TOPICS: Considers foundation on surface of homogeneous soil halfspace; foundation on surface of soil layer on rigid rock; embedded foundation and pile foundation; simple vertical dynamic-Green's function; seismic excitation; and dynamic soil-structure interaction. Features easy-to-use tables and detailed case studies. MARKET: For geotechnical engineers, structural engineers, and engineering mechanics specialists.
