Rehabbing Historic Buildings
Historic buildings often require structural upgrading before the cosmetics of restoration can be applied. Two case studies are presented here. The Four Seasons Hotel in Seattle required...
Earth Reinforced Dams: First in U.S.
Earth reinforcement has in recent years been applied in the restoration and construction of dams. Earth reinforcement has been used to raise dam heights, replace traditional earth embankments...
Pier Stabilization Eliminates Need to Reconstruct Damaged Bridge
After an ice jam near a six-span bridge restricted normal water passage, the ensueing high velocity water caused underscouring of one of the piers, leaving it ineffective as a bridge support....
Pile Construction Practices in Arctic Regions: State-of-the-Art
Pile installation techniques in cold regions include drill and slurry, and driven methods for foundation designs. In the past, piles used for structural support in permafrost have consisted...
Oil Rigs Designed to Combat Arctic Ice
Exploration and drilling rigs now being designed for use in the Beaufort Sea must withstand ice forces never before encountered. Design approaches include using the geometry of these structures...
Structural Lumber: An Overview of Research Needs
Structural performance of lumber is influenced by the processing steps from forest to final end-use and by the end-use environment. Research needs in processing include: 1) selection of...
Mechanical Fastening of Structural Wood Members?Design and Research Status
A brief overview is provided of the current mechanical fastening research base as background for a discussion of future research needs and priorities. A summary is presented of the current...
Structural Analysis of Light-Frame Subassemblies
Conventional light-frame subassemblies have a long history of good performance. Until recently this performance could not be quantified adequately because of the complex ways in which...
Heavy Timber Structures and Bridges
Development and application of treated glued-laminated timber is a landmark event in structural engineering history. The inertia of this event has produced continued, rapid and dramatic...
An Overview of Structural Panels and Structural Composite Products
Plywood has been the principal structural panel for construction since the late 1940s. Today, structural panels are evolving into products such as composite panels, oriented strand board,...
Reliability-Based Design for Wood Structures: Potentials and Research Needs
Wood as a renewable resource is briefly discussed to provide an understanding of the complex nature of the relationship between its availability and its efficient use for engineered construction....
Wood Trusses and Other Manufactured Structural Components
Roof trusses, floor trusses, wood I and box beams, and glued-laminated timber are discussed. Some of the major recommendations for future research include improved analytical techniques...
Structural Analysis of Light-Frame Wood Buildings
This paper reviews the information currently available and lacking that is needed for improving design procedures. Some initial attempts at theoretical analysis of entire wood buildings...
Structural Wood Research
State-of-the-Art and Research Needs
Timber is an abundant and renewable natural resource and its use exceeds all other construction material. Structural wood represents a challenge of vast dimensions and attention to various...
A Cost-effective Shallow Foundation Accommodates Three Feet of Settlement
An automotive maintenance facility to be built at the Anacostia Naval Station in Washington, D.C. had two major foundation problems: the probability of large settlement and the possibility...
World's Largest Installation of Fabric-Formed Pile Jackets
One major feature of fabric forming is permeability. One application of this technique is protective encasement of steel H and pipe piles at a major pier in Chile. The Huachipato Pier...
At Four Western Stadiums, Wood Comes Out on Top
In recent years, several long-span timber roofs have been constructed atop large arenas and stadiums in the Western states. The choice of glued-laminated timber offers designers good economy,...
Rx�Treated Lumber & Metal + Corrosion Ailments
The use of metal elements in contact with fire-treated lumber requires special precautions. It is a problem that has not received much attention in the literature directed to the design...
Evaluation, Maintenance and Upgrading of Wood Structures
Prepared by the Subcommittee on Evaluation, Maintenance, and Upgrading of Timber Structures of the Committee on Wood of the Structural Division of ASCE. ...
Shanghai Tunnel Projects Spur Construction Innovations
Since underground construction in soft ground is newly developed in Shanghai, there is little experience there as compared to what is known for specific sites in other countires. Well...
