Design Optimization of an All-FRP Short-Span Bridge
The objectives of this study are: a) to determine the feasibility of designing an all-FRP bridge, and b) to demonstrate the usefulness of optimization techniques in the design of FRP superstructures....
Seismic Resistance of Steel Fiber Reinforced Concrete Beam-Column Joints
This paper discusses the advantages of using steel fibers in seismic resistant beam-column connections. First, the effects of fibers on the various aspects of behavior of concrete are...
Built-Up Compression Members for Noval Structural Systems
This paper discusses built-up compression members used in novel structural systems for two high-rise buildings: InterFirst Plaza at Dallas Main Center and Columbus Center in New York....
Vibration of Composite Floors
An AISC/CISC guideline on floor vibration is being prepared to help practitioners design to avoid floor vibration problems and to remedy problems that occur in practice. This paper provides...
What is Optimization?
Basic concepts of optimization are described using design of a plate girder as an example. First, a way to formulate the problem as an optimization problem is presented. Then basic terminologies...
How to Optimize Steel Frameworks
This paper presents the details of a design synthesis strategy to conduct computer-automated design of least-weight structural steel frameworks, where members are automatically sized using...
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...
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,...
Jatiluhur Dam: Problems and Rehabilitation
The Jatiluhur Dam in Indonesia, completed in 1965, is an innovative design consisting of rockfill embankment with a clay core and a vertical cylindrical Intake Spillway. Within the Intake...
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...
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...
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...
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...
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...
Rehabilitation of Cracked Embankment Dams
Cracking is a common phenomenon in many earth embankment dams and especially those small to medium size dams constructed on compressible soil foundations. Collapsible soil conditions,...
The Stabilization of Concrete Dams by Post-Tensioned Rock Anchorages: The State of American Practice
Permanent post-tensioned rock anchorages have been used for over twenty years in America to stabilize existing concrete dams and their appurtenant structures. This paper provides a state...
Seismic Stabilization of St. Joe State Park Tailings Dams
Tailings dams constructed by the `upstream' method are known to be seismically vulnerable, but field experience indicates that their seismic stability usually improves following termination...
