This paper describes completed research and the status of research underway on timber bridges that are part of the USDA Forest Service timber bridge initiative. The initiative includes...

Replacing an Urban Foundation
Baltimore's new subway extension will pass close to a 6-story reinforced concrete building near the Inner Harbor. Its timber piling foundation was threatened by the dewatering...

Retaining Forest Roads
The U.S. Department of Agriculture, Forest Service, manages a vast system of roads which provide access to America's national forests. More than 250,000 miles of roads exist...

New Wharf Covers Trident Submarines
The U.S. Navy's newer fleet of Trident-class submarines requires upgraded support facilities. Work has continued on expanding the base at Kings Bay, Georgia. The explosive...

Fired Up at Fort Drum
The U.S. Army's first major privatization contract was signed for design, construction, operation and ownership of the Fort Drum powerplant at the newly constructed base for...

Expressway Centerpiece
The center span of the Napoleon Bonaparte Broward Bridge, better known as the Dame Point Bridge over the St. Johns River at Jacksonville, Fla., is the country's longest cable...

An Optimal Design of Steel Pipe Pile Foundation
This paper presents an optimal design method for the steel pipe pile foundation of bridge pier using a nonlinear programming. It is firstly assumed that an imaginary wall model behaves...

NDE for Performance of Wood Structures
Significant economic losses result annually due to deterioration and failure of structural wood components. A high percentage of these losses result from our current inability to assess...

Wood Diaphragms: Performance Requirements and Analytical Modeling
Wood diaphragms represent the principal mechanisms for resisting lateral loads in many light-frame buildings. While recent research has provided several mathematical models for predicting...

Lessons Learned from Dynamic Tests of Shear Panels
Thirteen 8-ft by 8-ft shear panels and fifteen 16-in by 18-in shear panels were tested dynamically at the Structural Testing Laboratory, Richmond Field Station, University of California,...

A Structural Analysis Model for Timber Shear Walls
A numerical modelling procedure for the non-linear analysis of timber shear walls is presented. The model includes the non-linear behavior of the connectors between the sheathing and framing,...

Load and Resistance Factor Design for Engineered Wood Construction
The wood industry has provided sponsorship for the development of a reliability-based, load and resistance factor design specification for engineered wood structures. This user-tested,...

Load Combinations for LRFD With Wood Construction
Probability based limit states design for wood construction is complicated by the fact that wood is a natural material with large variations in mechanical properties and is sensitive to...

LRFD for Engineered Wood Construction: Calibration to Current Design
The structural design code for engineered wood construction is evolving to a limit state design basis in which the safety checks are derived from the underlying probability distributions...

Member Design Equations for a LRFD Wood Specification
A key step in the preparation of a load and resistance factor design (LRFD) based design specification for engineered wood construction is the selection of the behavioral equations for...

LRFD: Progress for Engineers and the Wood Industry
The LRFD for Wood project represents a milestone for the industry. The significance of the project goes far beyond merely switching formats in design equations. The project signifies both...

Performance of Steel Sheet Pile Cellular Cofferdams
Steel sheet pile cells are often used as construction cofferdams for structures to be constructed in rivers. Examples of this type of construction include locks and dams, pumping stations,...

Analysis of Glulam Lattice Dome
Glued-laminated timber (glulam) domes have become competitive in the engineering of large-span roof structures. Three-way glulam grid domes, such as the Triax and Varax domes, are particularly...
