Aesthetic Issues in Timber Bridges
The vocabulary of visual design and several generally accepted major principles of visual design are reviewed in order to provide a 'context' for case studies of award-winning timber bridges....
Seismic Upgrades Using Energy Dissipation Devices
This paper presents a model for developing comparative seismic rehabilitation schemes for essential facilities using both conventional techniques and passive control devices. Essential...
Implementation of Passive Energy Dissipation Systems in the United States
Significant advances in the field of passive energy dissipation for improved structural seismic resistance have been made in recent years. Developments in research and analysis techniques...
Utilizing Visco-Elastic Dampers in the Seismic Retrofit of a Thirteen Story Steel Framed Building
A 13 story steel framed building in Santa Clara Country, California exhibited strong beating effects (torsional coupling) and prolonged building response as result of various seismic events....
Hi-Tech Seismic Rehabilitation of `Casino De Montreal'
The existing eight-story steel structure, built during 1966, lacked in lateral earthquake resistance and ductility requirements of the current building code. Introduction of friction-dampers...
Development of Hardwood Glulam Timber Bridge Standards
Design standards and specification for 5.5 to 27.4 m(18 to 90 ft.) clear span hardwood glued laminated (glulam) highway bridges have been developed and are available from the Pennsylvania...
Bulb-T and Glulam-FRP Beams for Timber Bridges
In this paper, we discusses the manufacturing, analysis, and testing of two glulam beam designers:(1) Southern pine bulb, and (2) yellow-poplar reinforced with pultruded fiber-reinforced...
Acoustic Emission Monitoring of Steel Bridges
Global nondestructive monitoring techniques are of great significance for rapid monitoring of bridges. One promising technique involves monitoring the microseismic events (Acoustic Emissions,...
Educating A Structural Engineer
It is important for universities to equip college graduates with a strong theoretical background necessary for sound engineering judgement. It is equally important for universities to...
When are Loads Taught? A Case Study and National Trends.
Several years ago, structures faculty of the Department of Civil and Architectural Engineering at the University of Wyoming revised their structures courses to meet several new educational...
Where do the Arrows Come From? Evaluating Structural Loads
Two elements of an undergraduate's structural education that are not treated well in most textbooks are (1) the development of correct loads and (2) load modelling-that is, how the load...
Experiences with an Undergraduate Structural Engineering Laboratory
An Undergraduate Structural Engineering Laboratory was recently implemented at Lehigh University with funds obtained from the National Science Foundation through its instrumentation and...
Teaching Structural Loading: A Case Study
CVEG 4803: Structural Loading course was formulated three years ago as an undergraduate senior elective course. In this course structural dynamics is introduced for one third of the course....
Sensors and Techniques for Structural Monitoring
This paper summarizes measurement requirements for the monitoring of engineering structures and describes new sensor/system configurations that are finding useful application in field...
Experimental Measurements of Dynamic Loads Imposed by Moving Crowds
Dynamic forces generated by moving occupants were measured using an instrumented forces platform. Experiments were conducted for several sets of loads due to individuals and groups of...
Prediction of Structural Response to Large Earthquakes by Using Recordings From Smaller Earthquakes
The feasibility of predicting structural response to large earthquakes by using recorded responses from collocated smaller earthquakes is investigated. Records from large earthquakes can...
Long-Term Monitoring of Civil Structures using Smart Structures Techniques
A smart monitoring program for a hybrid concrete-steel building in Washington, D.C. has been developed. The building is currently being instrumented with a variety of strain and corrosion...
Design and Construction of Post-Tensioned Concrete Floor Systems
This is a summary of the original full length paper which is available from the author. This paper assumes a basic technical knowledge of reinforced concrete design and prestressed concrete...
Tests of Full-Size Pretensioned AASHTO Beams with Debonded Strands
A summary of an experimental investigation dealing with the effects of strand debonding on the flexure and shear behavior of simply supported pretensioned AASHTO beams with a cast-in-place...
Nonlinear Analysis of Prestressed Concrete Structures
This paper presents a finite element model for the nonlinear analysis of prestressed concrete structures. The model can be used to analyze pretensioned or posttensioned, bonded or unbonded...
