*Resonant column tests were performed by six participants in a program designed to evaluate results from various devices. The participants were Drnevich, Hardin, Woods, Shannon &...*

Effects of Entrance Loss on Harbor Oscillations

*By assuming a head loss across the harbor entrance the wave-induced response in a rectangular model harbor is studied theoretically. The loss is assumed to be quadratic in local velocity...*

Response of a Column in Random Vibration Tests

*Laboratory experiments were conducted to observe and measure the response amplitude and frequency of a simply supported column. The column was excited by axial forces generated from sinusoidal...*

Resonance in Pipes having Variable Characteristics

*By using the Runge-Kutta Method, the field matrix for a pipeline having variable characteristics along its length is derived. This matrix can be used to determine the resonant frequencies...*

Resonant Response of Offshore Structures

*A nonlinear deterministic mathematic model is used to investigate the resonant response of a tall offshore structure under the action of periodic deep water waves. The added mass which...*

Vertical Vibration of Embedded Footings

*The theory makes it possible to consider soil as an elastic half-space or a stratum. In the latter case, embedment becomes particularly important because the omission of embedment leads...*

Dynamic Stability of Tube Conveying Fluid

*The parametric resonance of a simply supported tube is studied analytically. By employing Galerkin's method, the equation of motion is reduced to a system of coupled Mathieu-Hill-type...*

Channel Effects in Harbor Resonance
