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...
In-Situ Determination of the Compressive Stress-Strain Relationship of Multi-Wythe Brick Masonry
In-situ stress-strain relationships of existing multi-wythe brick masonry have been determined by introducing flatjacks into sawcuts made in the exterior wythe of the multi-wythe masonry....
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...
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...
Development and Evaluation of Remediation Strategies by Deformation Analysis
Deformation analysis is providing guidance for the most efficient and economical seismic remedial treatments for Mormon Island Auxiliary and Sardis dams. The computer program TARA-3FL...
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...
Seismic Rehabilitation of Echo Lake Dam
Echo Lake Dam is an existing dam raising a natural lake in the Sierra Nevada in California, along the western edge of the Tahoe Basin. The dam was an embankment built with steep, hand...
Graham Lake Dam Remedial Measures Project
Graham Lake Dam consists of a 550-foot long earth embankment and an 80-foot long concrete spillway. Several concerns were identified during project inspections including limited spillway...
Twin Lakes Enlargement and Rehabilitation
The Twin Lakes Enlargement and Rehabilitation Project involves an enlarged embankment replacing a two-tiered reservoir system with a single, larger-volume reservoir and new appurtenances....
