Regional Evaluation of Transportation Lifelines in New York State with the Aid of GIS Technology
Regional evaluation of transportation lifeline facilities which may be impacted by seismic and other natural hazards is of great concern for purposes of emergency planning and response...
Earthquake Countermeasures for Lifelines in the Central and Eastern United States
Seismic hazards affecting petroleum transmission systems in the Central U.S. and water and gas distribution systems in the Eastern U.S. are discussed. Experience during previous earthquakes...
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...
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...
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...

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...
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...
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...
Screening Old Offshore Platforms: Previous Approaches and Further Thoughts
Several possible levels of analysis are identified, each leading to both quantitative (economic) and subjective (human) risk evaluations. These range from ratings based only on historical...
The U.S. Naval Facilities Offshore Platform Inspection, Maintenance, Repair and Rehabilitation Program
The Department of Defense (DOD) owns many offshore platforms in various worldwide locations. These platforms are presently being utilized for training and long term research and development...
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...
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...
Simplified Methods for Assessment of the Structural Integrity of Existing Steel Jacket Platforms in the Gulf of Mexico
This paper presents the results of research to define a practical procedure for assessment of the structural integrity of existing steel jacket platforms in the Gulf of Mexico. An overview...
Skin Friction Distrtibutions on Piles in Sand
Presented in this paper are early results from an analytical investigation of the performance of a closed-ended pipe pile under monotonic axial loading in dense sand. The study was performed...
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....
Smart Structures
Detecting cracks in concrete before they become visible could help prevent structural collapse of buildings and other civil works, say professors at three schools of engineering. The University...
