A Multi-objective Criteria Analysis for Alternative Route Planning
A multi-objective criteria analysis was used to identify a proposed rail spur route with the optimal combination of low environmental impact, favorable engineering characteristics and...
Loading of Nutrients to Groundwater From High Source Areas During the Winter Period
Nutrient loading to surface, subsurface and groundwater in agricultural areas is the focus of control programs throughout the United States. In certain cases, high source areas can be...
Design Criteria and Specifications for Pipeline Rehabilitation Projects
Pipeline rehabilitation, while not a completely new technology, is nevertheless a fairly recent development, just now coming to the forefront as to common usage. It is not however a fail-safe...
Modeling Nutrient Loadings from Croplands in the Chesapeake Bay Watershed
The Chesapeake Bay Watershed Model, based on the U.S. EPA Hydrologic Simulation Program Fortran (HSPF) provides a framework for evaluating and quantifying nutrient loadings to the Chesapeake...
Advancing Anchorage Technology
An overview of earth anchorage technology, with emphasis on current U.S. corrosion protection practice as compared to that used in Europe. Comments from U.S. practitioners involved in...
A More Rational Approach to Pavements
It is the intent of this paper to demonstrate how purely probabilistic arguments can be used to formulate a rational (phenomenonological) model of the particulate media that comprise pavement...
Realistic Specifications for Steel Bridge Painting
Specifications play a vital role in a steel bridge painting contract. They not only can ease problems with painting construction, but can also provide a common standard for all parties...
Experimental Investigation of Self-Tapping Fasteners for Attachment of Corrugated Cladding Panels to Pultruded Fiber-Reinforced Plastics Beams in Industrial Building Construction
This paper describes an experimental investigation of self-tapping fasteners for the attachment of corrugated fiber-reinforced plastics (FRP) cladding panels to pultruded FRP beams. Although...
Investigation of the Behavior of Reinforced Plastic Columns with Concrete Core
This paper describes an experimental investigation into the behavior of reinforced plastic columns with tubular (hollow) sections. The columns were pultruded and had a cross-section which...
The Crown and the Curtain Wall
Crowning the complex curtainwall of an 870 ft concrete tower with a 150 ft high crown of aluminum masts in concentric rings above the 60th floor required ingenuity and extraordinary cooperation...
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...
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,...
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....
Empirical Simulation of Future Hurricane Storm Histories as a Tool in Engineering and Economic Analysis
Although the database of past storm occurrences and their detailed histories and geometries at or near a site is essential to planning safe and cost-effective future engineering operations...
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....
A Simple Method to Compute Wave Loads on a TLP
In this paper, analytic diffraction (Linton and Evans, 1990) and radiation (Kim, 1992) solutions for arrays of bottom-mounted vertical circular cylinders are used to compute hydrodynamic...
