How to Optimize Prestressed Concrete Systems?
Three common problems of prestressed concrete optimization, that involve only a single structural analysis and can readily be solved by available programs, are presented: 1. The problem...
How to Include Reliability Constraints in Structural Optimization
Structural optimization is a complex process made of design cycles aimed at finding the best possible solution. At each design cycle ultimate and/or serviceability limit states must be...
Teaching Structural Engineering in Year 2000
The paper addresses the need for changes in engineering education in order to keep pace with the changes that have and will continue to take place in the workplace. Over the past 40 years...
Interfacing Academia and the Practicing Profession
The paper presents a discussion of current topics and instructional methods in structural engineering in the United States. Following a review of typical subject matter in analysis and...
What Attributes Should the Structural Engineering Graduate Possess?
This paper will discuss the need for structural engineering students to be trained to think in terms of the performance of the structural system as a whole, rather than the individual...
Structural Analysis for the Student
The transition from student to practicing structural engineer can be a very 'eye-opening' experience. From the classical right-wrong classroom solutions of well-defined indeterminate structures,...
Structural Analysis in Context
The issues of what student should learn about structural analysis and how it should be taught are explored considering the purposes of structural analysis in engineering practice and the...
Development in Criteria for Dam Corrective Actions
Reviewed is the recent history of the Bureau of Reclamation (Reclamation) Safety of Dams (SOD) Program. Particularly, the development of decision philosophies and technical approaches...
Inspections, Evaluations and Modifications for Corps of Engineers Dams
The Corps of Engineers owns and operates 580 dams in the United States. As these dams become older (199 are over 50 years old), dam safety and modifications play an increasing role in...
Rock Structure in Relation to Concrete Dams on Granite
Granite is often considered to provide an excellent foundation for a concrete dam and a great many dams are thus founded on granitic rocks. Although granitic rocks lack the bedding of...
Numerical and Centrifuge Modeling of an Arch Dam on Jointed Rock
This paper addresses the stability of an arch dam built on highly fractured argillite. A large concrete thrust block combined with a wing dam forms the left dam abutment. The last FERC...
Three-Dimensional Stability Analysis of Carpenter Dam
This paper describes the three-dimensional stability analysis of Carpenter Dam. The presence of keyed construction joints between dam monoliths at Carpenter Dam can significantly affect...
Risk Assessment: A Tool for Dam Rehabilitation Decisions
A phased approach to the dam rehabilitation decision problem is presented. The approach is based on viewing the newer dam safety evaluation approaches of incremental damage assessment...
Reliability Analysis of Navigation Structures
Methods for probabilistic stability analyses of concrete monoliths at hydraulic structures were developed and tested. Numerous analyses were performed using data from six actual structures...
Design Considerations for Raising Existing Dams for Increased Storage
While a number of new dams have been constructed in the United States and other countries in recent years, much of the construction activity related to dams has involved the raising of...
Roller Compacted Concrete for Embankment Overtopping Protection
In the first National Dam Safety Inventory and inspection performed by the Corps of Engineers, the majority of deficiencies found were related to the inability of the project to retain...
Construction of CCM Overtopping Protection on Three Parkway Dams
Cellular concrete mat (CCM) systems have been installed as overtopping protection on three small embankment dams along the Blue Ridge Parkway. Based on field tests by others and on the...
Saylorville Spillway: Emergency to Service Spillway
The spillway for Saylorville Lake located on the Des Moines River, 12 miles north of the city of Des Moines, Iowa, a large metropolitan, was designed as an emergency spillway. Due to subsequent...
Seepage Control in Dam Rehabilitation
This paper is concerned with the control of seepage problems which develop in existing dams. It is prefaced with a discussion of attitudes and experiences that have evolved over the last...
Some Considerations for Remedial Grouting for Seepage Control
The inadequate performance of grout curtains and the consequent need for remedial and supplementary grouting of dam foundations probably arises, in essentially all cases, from a combination...
