Floor Live Load Models and Pattern Load Effects
Probabilistic models of sustained live loads and equivalent uniformly distributed loads are discussed with regard to pattern load effects. A simple equivalent pattern load is identified...
Reliability-Based Specification of Design Load-Effect for Penetrating Fragments and Debris
This paper presents the derivation and application of a simplified reliability-based approach for selecting design fragments/debris particles for use in protective design. Using this approach,...
A Multiple Presence Load Model for Bridges
This paper utilises weigh-in-motion data to simulate multi-lane traffic crossing short span multiple-lane bridges. In this manner the reduction factors for a multiple lane bridge are derived....
Optimizing Economic Returns in Drainage Design
Soil wetness is a limitation to high agricultural productivity in Northern New York (NNY) where some 325,000 ha of cropland require drainage treatment. Drainage is needed for trafficability...
Economical and Statistical Based On-Farm Irrigation Scheduling
Most irrigation scheduling techniques are not based upon the statistics of the irrigations or economics of irrigated crop production. Traditional irrigation scheduling is based upon average...
Technology Transfer to Developing Countries
Foreign assignments have proven to be the most interesting and rewarding part of a career for many western professionals. For success, however, care must be taken to assure that the individual...
Holistic Approach to Irrigation Management in Developing Countries
Sound development of irrigation and drainage projects in developing countries is a continuing need to reduce hunger, environmental degradation and excess population growth; and to promote...
Cloud Seeding: The Engineering is Done, but What About Social Impacts?
As engineers, we tend to focus on the technical aspects of cloud seeding, and may neglect important social aspects or potential side effects. Often people in the target area are more concerned...
High Level Radioactive Waste Management 1992
The proceedings of the third International Conference on High Level Radioactive Waste Mnagement, held on April 12-16, 1992, Las Vegas, Nevada, provides information on the technical and...
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...
A Competitive Framework for Evaluating the Economic Benefits of Port Improvements
This paper presents an economic model for analyzing the benefits and optimal timing of port capacity increases. The model is presented through a case study of the Port of Ningbo, along...
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...
Planning and Design Guidelines for Small Craft Harbors?Economic factors and Finance
The purpose of this paper is to present, in draft form, the fourth chapter of a technical report on the planning and design of small craft harbors being prepared by a special task force...
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...
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...
