Block objects, standing on a shaking foundation, tend to rock and may uplift. Rocking of buildings in earthquakes is of particular interest because human lives and high costs are at stake. Most previous studies on rocking are limited to two‐dimensi

Rocking or toppling of a cylindrical structure or object on a shaking foundation is a common occurrence of engineering interest. The behavior is analyzed with a simple three‐dimensional model which has an upright rigid cylinder standing on a rigid

The dynamic behavior of rigid-block structures resting on a rigid foundation subjected to horizontal harmonic excitation is examined. For slender structures, the nonlinear equation of motion is approximated by a piecewise linear equation. Using this

The stochastic rocking of a rigid block due to shaking of its foundation is examined. The foundation is flexible (Winkler) and its independent springs and dashpots separate from the block base when tension is incipient. Modulated white noise is used

A three-dimensional dynamic analysis of nonhomogeneous earth dams is presented. The analysis is based on the Rayleigh-Ritz method and on the assumption that the dam materials are isotropic and linearly elastic but have properties which can vary as fu

The rocking of a rigid rectangular block on two types of shaking foundations is examined. The foundation is either a rigid plane, or a flexible (Winkler) foundation whose independent springs and dashpots separate from the block base when the springs
