Wind Studies of the Owensboro Bridge, Kentucky
Wind tunnel studies on the Owensboro Bridge are described in this paper, including 1:50 scale sectional model tests and 1:160 scale aeroelastic model tests. Comparisons are presented and...
Fracture Analysis of Bolted Timber Connections
Application of fracture mechanics concepts to splice connections where bolts load timber members perpendicular to the grain is discussed. Attention is given to prediction of the load level...
Validation of the European Yield Model for Nailed Connections
Recent changes in National Design Specification for Wood Construction (NDS) connection design methods make it necessary to validate the European yield model (EYM) for nails. Test values...
Special Considerations in the Design of Connections for Recycled Wood/Plastic Composite Lumber
There is current work in the American Society for Testing and Materials (ASTM) to evaluate potential test methods for what they refer to as 'commingled' plastic lumber. This category covers...
Low Strain Dynamic Testing of Wood Piles Supporting an Existing Pier
This paper presents a case history where low strain dynamic testing was performed to test wood piles supporting an existing structure. Under consideration is a 183 m long wooden pier constructed...
Timber Pile Length Determination Using a Nondestructive Technique
Determining timber pile length is critical when evaluating the potential effects of scour and for determining pile capacity. Unfortunately, records of timber pile lengths are typically...
Biaxial Testing of Brittle Repair Material for Rigid Pavements
Most codes of practice prescribe procedures for selecting patch configuration and material based on test devised for evaluating new pavement materials. This study is aimed at examined...
Current and Future Research in Steel Bridge Structures
The topics I have listed are ones which I am aware through discussions with various researches, designers, and industry representatives. The list of topics is presented as a starting point...
Pre-Engineered Short Span Steel Bridges
The American Iron and Steel Institute has developed a package to aid in expediting the design of short-span steel bridges for use by owners, designers, fabricators, and contractors in...
Time-Dependent Load-Distribution Behavior of Parallel-Member Wood Systems
The effect of differential member creep on the load-distribution behavior of parallel-member wood systems is examined. Variability in the creep response of the individual component members...
Rigid Beam-To-Column Connection Detail for Circular Composite Columns
Steel pipes with relatively thin wall thickness and filled with high strength concrete have been used in building construction. Some of the advantages of this type of column include eliminating...
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...
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....
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...
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...
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...
The Slender Tower of 52-54 East End Avenue
The structural system for the 52-54 East End Avenue project is presented. The 40 story residential tower with as aspect ratio of 12: 1 is one of the most slender buildings constructed...
LRFD vs. ASD for Wood Structures
There is a growing preference within the structural engineering community for the adoption of reliability-based load and resistance factor design (LRFD) procedures in lieu of traditional...
