Cone Models for a Pile Foundation
A single pile in a soil halfspace is modeled for dynamic excitation with disks and their corresponding double cones. This simple one-dimensional strength-of-materials approach provides...

The Superposition Approach to Pile Group Dynamics
A general three-dimensional boundary integral formulation for pile groups is used to obtain a set of dynamic interaction factors for a number of soil profiles and for a wide range of pile...

An Alternative Analysis of Vibration Tests on Two Pile Group Foundations
Published quick-release horizontal vibration tests on two pile group foundations supporting large transformer banks are analyzed in this paper using the dynamic impedance approach embodied...

Observed and Predicted Response of Piles Under Dynamic Loads
Vibration tests were conducted on a single pile 450 mm diameter and driven to a depth of 17 m. The dynamic soil properties were also determined by conducting in-situ tests. The response...

First and Second Order Dynamic Subgrade Models for Soil-Pile Interaction Analysis
The three-dimensional continuum solutions are used to examine the physical insight of a first order dynamic subgrade model, originally applied by Novak for dynamic pile response analysis....

Effects of Liquefaction on Lateral Pile Responses
The potential significance of the impact of liquefaction on the dynamic response of pile foundations has been studied through a numerical study. Results of this study demonstrated that...

Soil-Pile-Superstructure System in Liquefaction
To obtain the dynamic behavior of the soil-pile-superstructure system in a liquefied sand layer, shaking table tests by using large scale shear bin (4m in length, 2m in width and 2m in...

Engineering Pre-engineered Buildings
Pre-engineered buildings have become more sophisticated. There are several manuals and guides on how to engineer the so-called pre-engineered structures, but none are complete. There are...

Offshore Structures?Past, Present, and Future
A review of the evolution of offshore platforms concludes that the process is ongoing. New configurations continue to emerge and the range of applicability continues to expand. Today's...

Wave Exciting Forces on a Platform Fixed in Nonlinear Shallow Water Waves
This paper presents the result of an experimental observation of cnoidal waves and the nonlinear wave loads on a fixed barge in a 2-dimensional wave tank. The Ursell numbers of the waves...

Upper Bound Limit Analysis of Deep Skirt Structures' Foundations
A solution to the problem of determining the bearing capacity of an embedded footing (foundation) subjected to arbitrary loading is being presented herein. It is primarily intended for...

Old Problems and New Challenges in Marine Geotechnical Engineering
The discipline of marine geotechnical engineering originated nearly five decades ago, primarily as a result of the offshore oil and gas industry. As this industry moved into deeper waters,...

Piles Under Dynamic Loads
This proceedings, Piles Under Dynamic Loads, consists of papers that try to identify the state of practice in the analysis and design of pile...

Under the Undersea World
Soil conditions in New Orleans are generally unfavorable to the construction of large structures, and exceptionally so along the Mississippi River banks, which tend to slide. But that...

Experimental Study of Adfreeze Heaving of Augered Caisson Footings
In order to establish the required depth of augered caisson-type footings in cold regions and their optimal design against adfreeze heaving, an experimental field investigation has been...

Processed-Snow Foundation Design at the Summit of the Greenland Ice Cap
The design and construction of a processed-snow foundation berm for an elevated building located at the summit of the Greenland Ice Cap is described. Weather conditions and design provisions...

A Mechanistic Approach to Pavement Design for Nome Airport
The analysis of performance and design of the pavement structure for the North-South runway at Nome Airport is based on the mechanistic approach. In the mechanistic approach, calculated...

Treatment of Unstable Foundation Areas in Alaska's Pavement Management System
In the State of Alaska Department of Transportation and Public Facilities Pavement Management System (PMS) unstable foundation areas are defined as sections of roadway that experience...

Minnesota Road Research Project - An Overview
The Minnesota Department of Transportation in cooperation with the Federal Highway Administration and the Local Roads Research Board of Minnesota is constructing the Minnesota Road Research...

Modeling of Floating Ice Sheets
Rectangular finite elements are studied and their suitability to investigate behavior of floating ice sheets is discussed. A simple model of the plate on one parameter, Wrinkler type,...
