Response Study of a Flexible Building Using Three Earthquake Records
This paper examines the response of a flexible building during three earthquakes. The records from the building are long and contain low frequencies. The site frequency (0.33-0.38 Hz)...
Aesthetic Considerations in the Design of a Stack Extension
The Connecticut D.E.P. mandated increase in height of the boiler stack at Backus Hospital in Norwich, CT presented many problems. Adding a new 45 foot vertical section atop the old brick...
Civil Engineering and Civic Monuments: The Commissioning, Design and Public Perception of Urban Infrastructure Projects
This paper analyzes the roles that some infrastructure projects play as civic monuments and public places, and how these functions interact with their technical performance and utility....
Bridging the Gap Between Architecture and Engineering
Building design is interdisciplinary by nature. Indeed, the collaboration of architect and structural engineer is critical to the success of building design projects. Yet with few exceptions...
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...
Design and Field Performance of a Metal-Plate-Connected Wood Truss Bridge
This paper describes an on-going study on the design and performance attributes of an experimental wood-truss bridge. This is believed to be the first roadway bridge application of metal-plate-connected...
Acoustic Emission Monitoring of Fatigue Crack Growth in HSLA-80 Steel Box Beams
An acoustic emission is a transient elastic wave generated by the rapid release of energy from a localized source within a material. There can be many sources of acoustic emission in a...
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...
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....
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...
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...
A Probabilistic Approach to the Response of Tall Buildings to Wind Loadings
Tall buildings constructed in recent years are light in weight, flexible and low in damping. This is the consequence of using lighter material with higher strength, and fewer interior...
Gust Speeds in Hurricanes
Based on strip-chart records of wind speeds representing 11 recording stations and four hurricanes, it is concluded that gust factors for hurricanes generally exceed the gust factors proposed...
Extreme Winds Estimation by `Peaks Over Threshold' and Epochal Methods
With a view to applying the 'peaks over threshold' method to the estimation of extreme wind sped data, we perform Monte Carlo simulations for which the parameters of the population distributions...
