An Overview of the Potential Applications of Neural Networks in Civil Engineering
Neural networks are computational models inspired by the structure and operation of the brain. They are massively parallel systems, made up of a large number of highly interconnected,...
Durability and Ductility of Advanced Composites
In recent years, several fiber reinforced composites have been successfully used as prestressing materials for demonstration highway structures. Since these materials are relatively brittle...
A Model Specification for Pultruded Structural Shapes: An Industry Collaborative
The use of pultruded products is steadily increasing. To support this growth, the industry has identified the need for a collaborative effort in developing standards that form a base line...
Steel Fiber Reinforcement in Structural Application
Ribbon Technology Corporation's use of steel fiber reinforced concrete in the construction of their new manufacturing and office facility in Gahanna, Ohio. Cost savings are obtained by...
The Use of Built-Up Compression Members?A Fabricator's Viewpoint
A variety of cross-sections of built-up compression members that have been used are shown. Suggested items that need to be addressed for the successful design and fabrication are discussed....
A New Theory of Built-Up Columns
In laced, battened and other built up columns the shear stiffness of the web can have a significant effect on the overall buckling load. At the present time, such columns are analyzed...
Achieving Level Composite Steel Floors
Constructing deflected composite steel floors that are level is a complex operation, and one which requires cooperation and an exchange of information between the structural engineer and...
Steel Bar Joist Performance: Design Deficiencies and Defects
Several failures of steel bar joist roofs have been investigated by the authors in the past decade. Many of these failures or performance problems have corresponded to bar joists manufactured...
Ambient Vibration Response of a Long Span Bridge
Natural frequencies, mode shapes and damping characteristics for a long-span cable-stayed bridge were experimentally determined from a series of ambient vibration tests for both the cantilever...
Remote Monitoring of a Stressed Timber Bridge Deck
The long term behavior of a CCA treated stressed timber deck bridge is being monitored, at present, using a remote data acquisition system. The bridge which is located in Gray, Maine was...
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...
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...
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...
Embankment Dam Safety
Procedures for identification and evaluation of conditions which can lead to catastrophic dam failure through either piping or deep seated instability of the downstream surface are presented....
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...
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....
