Post-Buckling of Plates in Compression and Bending
The elastic post-buckling behavior of rectangular plates in combined compression and bending is presented. The theoretical investigation begins with the Marguerre's compatibility...

Local and Overall Buckling of Welded Box Columns
An experimental study is presented on the local and overall interaction buckling strength of welded built-up box columns made of high strength steel. A total of twenty-seven box columns...

Prestressed Steel Grid Erected with Bent Forms
A new method for constructing one-layer steel grids erected by prestressing with the aid of recoverable bending forms is presented, followed by an approximate structural analysis. The...

Automated Accident Location Systems
State transportation agencies continue to seek better ways to identify road improvement needs. Research and development funds have been allocated to seek efficient methods for identifying...

Selection of Pavement Joint Sealant Material
A review of literature shows joint sealant selection should be based on the design, construction and environmental variables. Satisfactory performance for one set of conditions does not...

Decision Strategy for Asphalt Pavement Recycling
A decision model that uses utility theory to the decision making process in selecting optimum techniques for asphalt pavement recycling is presented. The model requires the identification...

Highway Fiscal and Program Management for the 1980s
The 1980s are a time of rapid change to most transportation agencies in the country—change in a funding base, which has remained essentially stable for the last 60 years, and change in...

New Structural Systems for Zero-Maintenance Pavements
Unique and infrequently used concepts and systems suitable for zero-maintenance pavements are identified. For this study, a zero-maintenance pavement is defined as one that will provide...

Recreational Travel: Gasoline Shortages and Price Increases
An empirical study utilizes visitation data from a number of recreational attractions in California to estimate the reduction of travel due to the gasoline price increases that occurred...

U.S. Geological Survey Federal-State Program
The U.S. Geological Survey Federal-State Cooperative Water Resource Program is a partnership between the Geological Survey and State and local agencies for the collection of the hydrologic...

Water Law Primer
An overview of legal principles controlling water resources use and development is provided. The body of legal principles is a combination of federal and state law, with federal law generally...

Evaluation of Environmental Assessment Methods
Twelve representative methods for environmental assessment are described, evaluated, and compared in terms the following seven evaluation criteria: treatment of the probabilistic nature...

Reservoir Management in Potomac River Basin
Techniques for determining the yield of multireservoir water supply systems have been developed and applied to the system that serves the Washington, D.C. metropolitan area (WMA). This...

TVA Hydro Scheduling Model: Practical Aspects
Computer programs and mathematical methods have been developed to model long term week-to-week variations in water level, discharge and electrical generation for the 42 reservoirs operated...

TVA Hydro Scheduling Model: Theoretical Aspects
The optimization procedures used in the Tennessee Valley Authority (TVA) HYDROSIM model are described. Scheduling of the TVA operated reservoir system poses a stochastic, nonlinear, multireservoir...

Investigation of Daily Flow Forecasting Models
Two types of models for forecasting daily flows from a basin are investigated. These model types are a segmented model whose components are multi-input linear models of the basin between...

An Alternative to the Peripheral Canal
The present mode of water transfer through the Sacramento—San Joaquin Delta is not adequate to meet both future export requirements and maintain desired water quality. A 42-mile long Peripheral...

Elasto-Plastic Settlement of Rigid Footings
A simple method of estimating elasto-plastic settlement of circular or annular centrally loaded footings is presented. The method incorporates the elasto-plastic behavior manifested through...

Piping Potential of Weak Zones Under Concrete Dams
A method is presented for evaluating the piping potential of shear zones crossing the foundation of a concrete dam from upstream to downstream. The steps described for this method involves...

Interaction of Soil and Penetration Projectile
The motion of a terradynamic penetrator is formulated, and some interaction characteristics as the added mass and the interaction pressure distribution are calculated. The magnitude of...
