Impact on Water Supply of a Seismically Damaged Water Delivery System
This paper presents the damage evaluation of a water delivery system caused by the ground shaking in the event of an earthquake by using the LIFELINE-W computer program. The adequacy of...

Seismic Hazards in the Eastern U.S. and the Impact on Transportation Lifelines
In the eastern US seismicity is low, hazard is moderate, and risk is quite high, especially in metropolitan regions with vulnerable transportation systems typically not designed to resist...

Transportation Lifeline Losses in Large Eastern Earthquakes
In December 1991 Applied Technology Council (ATC) and its subcontractor, EQE Inc., completed a 2-year Federal Emergency Management Agency-sponsored study to assess the seismic vulnerability...

Seismic Hazard Along a Central U.S. Oil Pipeline
An integrated approach is used to evaluate seismic hazards at six sites where pipeline 22 crosses the major rivers in West Tennessee. On the basis of historical and instrumental data,...

Seismic Hazard Analysis for Crude Oil Pipelines in the New Madrid Seismic Zone
The seismic vulnerability of three crude oil pipelines in and around the New Madrid Seismic Zone (NMSZ) is evaluated for a repetition of the 1811-12 New Madrid events. The seismic hazard...

Response of Model Pile Groups to Strong Shaking
The dynamic responses of small model pile groups to strong shaking obtained primarily from shake table tests are described and analyzed. As a basis for understanding pile group response,...

Seismic Pile-Group?Structure Interaction
A detailed multi-step procedure is outlined for a complete seismic soil-pile-foundation-structure interaction analysis, within the format of kinematic-inertial decomposition. Newly-developed...

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...

Forced Vibration Testing of an Expanded Base Concrete Pile
Forced vibration testing of a full-scale cast-in-situ expanded base concrete pile supporting a structural mass was conducted as part of a test pile program for a paper mill expansion at...

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...

Dynamic Parameters Analysis of Piles
This paper presents an analysis for the dynamic parameters of a single pile. The analysis allows consideration of pile-soil interaction, soil natural layered behavior and floating pile...

Design Loads for Sloshing in TLP Pontoons Tanks
Impact of fluid inside the Auger TLP ballast tanks on tank walls was investigated and changes made to the structural design in an accelerated fashion through the use of model testing....

Measured and Simulated Response of a Small Semisubmersible Moored in Deep Water
Small semisubmersible platform concepts are proposed for electronic tracking ranges, single-well petroleum production, and oceanographic data collection. This paper summarizes a major...

Flexible Membrane Wave Barrier
A linear analytical model is developed for the dynamic response of a flexible membrane wave barrier. The wave barrier consists of a thin flexible membrane suspended in the water column...

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...

Broadside Current Forces on Moored Ships
A method of estimating the static lateral current force on ships in deep and finite depth water is presented for the case of the current broadside to the ship. The method is based on recent...
