Stability Under Seismic Loading
This publication includes five papers that cover the p- ? effect on seismic structures with semi-rigid connections, the effect of panel zone deformations on the structural response behavior,...
Bridging the Joints in Bridges
Most bridges are designed with gaps in them. The cracks allow bridges to expand and contract as the temperature changes. But water can enter these gaps and foul bearings and structural...
Facility Location and Land Use
The Urban/Rural Dilemma
Most land use planning techniques focus on large metropolitan areas, with relatively little attention paid to smaller communities. Recent issues such as nuclear power plant location, water...
Seismic Evaluation of Lifeline Systems?Case Studies
This book contains the papers presented at the technical session titled Seismic Evaluation of Lifeline Systems?Case Studies at the ASCE Fall Convention in Boston, October 27-31, 1986....
Arctic Penetration Test Systems
Geotechnical exploration in offshore arctic regions relies upon the electric Cone Penetrometer Test (CPT) because of its speed, economy, data continuity, and general reliability. By adding...
Analysis of a Production Well Through Sediments Containing Gas Hydrates
In some of the petroleum reservoirs recently discovered north of the Arctic Circle, production wells extend through thick permafrost. Several authors have reported zones of gas hydrate...
Method for Weakening the Ice Cover in Northern Rivers
The recent acceleration of development activities in the North, mainly related to the development of oil and gas fields, has necessitated the bridging of many arctic streams. In such streams,...
Asphalt Revetments for Slope Protection in the Arctic
Experience in the Netherlands demonstrates that slope protection of coastal embankments subjected to heavy wave action can be accomplished with lining systems made of mixtures of asphalt...
Research Challenges in Frozen Ground Pile Design
A fairly recent pile design analysis is reviewed. The influence of such factors as temperature, salinity, loading, etc. on frozen ground pile design is pointed out. Since many facets of...
Ice Forces on Port Structures Resulting from Moving Ships
Results are described of experiments carried out in Thunder Bay Harbour in March, 1984, to measure ice forces on a port structure. Ice forces were measured by installing five pressure...
Structural Retrofit for Nuclear Power Plants
Retrofitting of nuclear power plants is a major concern these days. Recent rulings of regulatory agencies have affected most of the generating plants in some way. The lessons learned from...
Seismic Probabilistic Risk Assessment for Critical Facilities
Probabilistic Risk Assessment (PRA) for seismic events is currently being performed for nuclear power plants. The background on seismic PRA is presented along with a basic description...
Snow Effects on Pile Design Temperatures
The construction of North Slope aboveground pipelines and gathering lines is generally from snow workpads constructed proximate to existing access roadways. The pile support centerline...
Noise and Air Blast from Construction Blasting
Noise generated by construction blasting differs from other construction noise because of its frequency content. The audible high frequency portion is accompanied by a non audible, lower...
Can Clay Liners Work?
Nearly all liners for landfills and surface impoundments were constructed from compacted clay until about five years ago. But this is no longer so. In the past few years, clay liners used...
On the Design of Continuous Composite Beams
Methods of analysis and design of continuous composite beams are presented. Numerical analysis is used to determine the effective width of the slabs to be used in design. The influence...
Evaluation of the Effects of Temperature and Oxygen Concentration on Lignin Biodegradation
Color in natural waters has been attributed to humic substances which are believed to originate as by-products of lignin biodegradation. The purpose of our research was to examine the...
Computer Simulation of Lime-Soda Softening of Cooling Waters
A computer model is developed to simulate the process of lime-soda softening of cooling waters. Results from the model are compared with those from a laboratory experimental study using...
Oil Spill Detection by NOAA/AVHRR on Persian Gulf
An area of oil spills on the Persian Gulf was detected by the thermal-infrared channels of Advanced Very High Resolution Radiometer (AVHRR) on NOAA-7. AVHRR gives the temperatures of the...
Modeling the Fate and Transport of Biocides in Estuarine Power Plant Cooling Water Discharges
This paper presents a framework with examples for understanding the fate and transport of cooling system discharges into estuaries through the use of modeling. The modeling of biofouling...
