Live Load Models Based on WIM Data
The objective of the paper is to present the results of weigh-in-motion (WIM) measurements carried out in Michigan. Selected bridges were instrumented and truck weights and axle configurations...

Environmental Impacts of Agricultural Drainage
Research has shown that improved drainage increases peak runoff rates and pollutant loads compared to natural conditions. However improved drainage on agricultural lands may reduce outflow...

Pile Lateral Load Test in the Port of Los Angeles
Recent wharf projects in West Coast ports have featured rock dikes to contain backland fill and the use of vertical piles embedded in the rock dikes to resist lateral loads. This paper...

Seismic Rehabilitation of Seattle's Pier 69
The Port of Seattle, one of the largest on the west coast of North America, made a strong statement regarding their support for reusing existing structures when a decision was made to...

Pre-Compression of Concrete Breasting Dolphins Solves Construction Problem
A roll-on/roll-off ferry terminal was built in Quincy, Massachusetts in 1989 as part of a marine transportation system to support construction of the sewage treatment facilities proposed...

Bulk Commodity Terminals?Planning for the Future Competitive and Environmental Challenges
The demand upon all industries for better protection of the environment is increasing and the regulations and permit requirements are changing rapidly. Bulk commodity terminal operators...

Floating or Fixed Dock for RO/RO Ship Operations
Floating pontoon-type dock structures are typically used for RO/RO ship berthing. Primary advantage of a floating dock for RO/RO berthing is the relatively constant height relationship...

Model Tests for Expansion of Anaheim Bay Naval Harbor
Modifications to the Anaheim Bay, California, Harbor complex have been proposed to enable larger ships to access the existing wharf for direct loading of ordnance. In addition, new deepwater...

Assessment of Derived Flood Frequency Distributions
Derived flood frequency distributions based on the geomorphologic IUH are evaluated in this work. Two existing approaches, the methods of Hebson and Wood (1982) and Diaz-Granados et al....

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...

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...

Adhesives and Structural Plastics
An overview of some primary considerations for the use of adhesives and their advantages in connection of structural plastics is presented. Effective joint geometries, surface preparations,...

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...

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,...
