Performance Monitoring of Concrete Structures with Embedded Sensors
This paper describes the use of embedded fiber optic sensors to monitor the performance of reinforced concrete structures. The fiber optic sensors are capable of measuring vibrations,...
Monitoring Performance of Full Scale Structures
General Physics Services Corporation (GPSC) of Columbia, Maryland has developed a device for the remote long-term monitoring of full scale structures, such as highway bridges. This patented...
Full Scale Dynamic Monitoring of Highway Bridges
Sensitivity of identified modal properties by physical testing is critical for automated monitoring of bridge structural condition. It is investigated here considering flexure modes and...
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 Reinforced Concrete Systems
A straightforward procedure for the optimization of member dimensions and reinforcement design in concrete structures consisting of beams, slabs, and columns is presented. The procedure...
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 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...
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...
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...
