Earthquake Hazard Investigative Procedures for Central United States Waterworks
The vulnerability assessment of Central United States waterworks for earthquake hazards is a developing engineering practice for civil engineers in Arkansas, Missouri and states close...
Seismic Mitigation of the Memphis Water System
Memphis, Tennessee is located in zone 2 of the 1988 Standard Building Code, close to the New Madrid Seismic Zone. The probability of having a seismic event of significant magnitude is...
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...
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...
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...
Sea Floor Wave-Induced Water Kinematics for Design of Pipeline
A statistical model is presented for horizontal velocity and acceleration of water particles beneath storm seas near the sea floor. An expansion of the kinematics with basis functions...
Cyclic Behavior of a Deepwater Normally Consolidated Clay
A comprehensive advanced laboratory testing program was undertaken to study the cyclic behavior of clays under various combinations of one-way and two-way cyclic loading. This work was...
Effects of Freezing on Impact Properties of RTM Composites, and Their Applications in Offshore Structures
Resin transfer molding is rapidly being acknowledged as the process with potential to create perhaps the purest form of a composite material as representative of the concept of `material-by-design.'...
Dynamic Response Characteristics of Jack-Up Drilling Units
The effects of five parameters on the dynamic amplification of the global base shear on a deep water jack-up drilling unit were analyzed using a time domain nonlinear model. The five parameters...
A Fourier Series Solution to Bottom Roughness Induced Stresses During Pipe Laying
Often during installation, a subsea pipeline must be laid along seabed portions with rough profiles. The pipeline is forced by the bottom irregularities to bridge across consecutive protuberances....
Lifeline Earthquake Engineering in the Central and Eastern U.S.
This proceedings,
Measured to the Max
Engineers looking to model the behavior of a structure under seismic conditions often ignore the best source of data available: the building itself. Full-scale measurements of vibrations...
Seismic Assessment of Tailings Dams
A significant portion of the operating and closed large dams in North America are tailings dams used to impound wastes from mining operations. Often these dams were built by mine personnel...
Thermal Strain Behaviour of Clays Cooled to Cryogenic Temperatures
The thermal expansion behaviour of two different types of clays (Boom clay from Belgium and a pure kaolinite-water paste) has been studied in a temperature range from +20? to -150?C (LNG...
A Laboratory Study of Shock Waves in Frozen Soil
This work has focused on two aspects of dynamic behavior of frozen soil: first, on the shock pressure attenuation, and second, on the shock Hugoniot. The use of long bars of frozen soil...
New Admixtures for Cold Weather Concreting
Chemicals were tested for their ability to promote strength gain in portland cement concrete at low temperature. The admixtures depressed the freezing point of the mix water and accelerated...
Environment One: A Master Plan Study for a New Scientific Research Station at the Geographic South Pole
The existing research station at the geographic South Pole is approaching the end of its useful life. This master plan study focuses on determining the technical and functional requirements...
Friction and Cohesion in Ice Rubble Reviewed
An argument is ventured that accumulations of ice rubble undergoing continuous shear deformation are essentially cohesionless. In terms of the Mohr-Coulomb failure criterion, therefore,...
