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...

Evaluation of Seismic Vulnerability of Highway Bridges in the Eastern United States
For high risk seismic zones such as California, the state-of-the-art in earthquake resistant design for new highway bridges has been well advanced, especially since the damaging 1971 San...

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...

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...

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...

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....

Nonlinear Wave Runup on Large Circular Cylinders
Various design methods for computing nonlinear wave runup on a large-diameter circular cylinder are presented. First, empirical correlations are developed between the observed maximum...

Computer Aided Design for Deep Water Offshore Risers
This paper describes a software package (OTRC-Riser-91) that was developed under the sponsorship of the Offshore Research Technology Center that is funded by the National Science Foundation...

The Mother of All Resilient Structures: Fixed-Base Tower in 3000-Foot Water and Some Outstanding Issues
This paper describes design and development work for 40- to 80-well fixed- base - yet compliant - towers for 2000- to 3000-foot water depths. Technical issues which are covered include:...

Design of Tension Leg Platforms: A Knowledge Based Approach
Tension leg platforms (TLPs) are floating compliant platforms designed for deep water offshore hydrocarbon production. Only a few TLPs have actually been built, but others are currently...

Predicting Fate and Effects of Hydrocarbons in the Oceans
Three major sources of hydrocarbons exist in the oceans. One is from oil spills related to the production and transportation of hydrocarbons. The second, while generally not spectacular,...

Wave Effects on Offshore Structures?Some Recent Research
The present paper summarizes methods of estimating wave effects on offshore structures, and highlights a selection of recent related research. Initially, certain aspects relating to the...

Re-Qualification of Offshore Platforms
Older platforms that are being re-qualified for extended service involve many technical problems that are unlike those associated with design of new platforms. Procedures to help resolve...

Reliable Design-Wave Force Predictions for Seabed Pipelines
The results of three separate field research projects have been pulled together to provide a design formula for maximum wave-induced horizontal force on a submarine pipe. This broadly-applicable...

The SIMBAT Software Package for Stochastic Interpolation of Ocean Wave Kinematics as an Aid in the Engineering Design of Large Floating Structures
Geostatistical techniques of nonconditional and conditional simulation are used in a new public domain computer software package, named SIMBAT, to stochastically interpolate ocean wave...
