A Bridge Management System Module for the Selection of Rehabilitation and Replacement Projects
A procedure, developed for the state of Texas is reported, which determines an allocation budget for bridge replacement and rehabilitation projects, using multi-attribute criteria and...
A Microcomputer Aided Bridge Management System
This paper presents a microcomputer based software system suitable for a local agency which will permit a local bridge system to be systematically evaluated with the use of a bridge management...
Technical Work on Flexible Pipe/Soil Interaction Overview?1990
Research in the laboratory and field have been ongoing for the past seventy years on flexible pipe/soil interaction. Virtually all of the early work was done on steel pipe. During the...
The Great American Pyramid
For more than 50 years officials of Memphis, Tenn. have wanted to establish a link to their Egyptian namesake--and they will, through a pyramid. As opposed to its Egyptian forerunners,...
Florida Bridges Beat the Clock
Today, when budget overruns and delays on construction projects are the rule more than the exception, 11 precast segmental balanced cantilever bridges on two contracts were recently completed...
On the Drawing Board
Reliable and quantitative nondestructive evaluation (NDE) methods for construction materials of wood, concrete, masonry and structural steel are needed. NSF program director John Scalzi...
Bridges Under Surveillance
Although bridge monitoring is still in its infancy, research, pilot studies and field work are underway across the country. While today it's still a pie-in-the-sky goal, the...
Northumberland Strait Crossing Project?A Public-Private Venture
This major project has challenged the Canadian Government to produce innovative requirements in environmental planning, financing and security, and facility performance. It requires a...
Translating Bridge Tolls to a New Bridge: The Third Dartford River Crossing
In March 1986, the Department of Transport of the United Kingdom Government published Guidelines inviting promoters for the submission of private sector bids for the design, construction...
Design of Steel Transmission Pole Structures
Hydraulic Bridge Design for Movable Bed Conditions
This paper addresses the practical considerations of hydraulic design of a bridge under movable bed conditions. Hydraulic design tasks include pier and abutment scour calculations, design...
Alignment of Large Flood-Peaks on Arid Watersheds
Bridge and culvert design requires estimates for 25- to 100-year return period flood peaks (Q). Floodplain delineation calls for 500-year (Q500) estimates. Arid western flood series are...
Hydraulic and Scour Analysis for Muitiple Crossings of the Salt River, Phoenix, Arizona
Two new freeway systems currently being designed for the Phoenix metropolitan area, the East Papago Freeway and the Outer Loop Highway, will both cross the Salt River within a one mile...
Critical Flow Through Bridge Piers
A physical model study was performed at California State University, Long Beach to investigate the location of critical depth within bridge piers in supercritical lined channels. This...
The Future of Steel Structures
The future availability of steel as a construction material is covered in this paper. The advances in the material, design fabrication and erection are discussed. The quality and quantity...
Decayed Timber Bridge Microcomputer Rating Program
National Bridge Inspection Standards (NBIS) require that capacity ratings for each bridge structure be established. This requirement includes timber bridges which are often decayed, have...
Sawn Lumber in Bridge Construction
This paper covers many aspects of design and construction that affect the specifications of the sawn wood components of a highway bridge. The relationships between the grading rules for...
Glued Laminated Timber for Bridge Construction
Structural glued laminated timber (glulam) was first introduced into the U.S. as a construction material in 1934. With the development of fully waterproof adhesives in the 1940's,...
Structural Wood Composites in Bridge Construction
Wood composites, known collectively as Structural Composite Lumber (SCL), are a family of wood-based products that better utilize the available wood fiber of a tree. This paper describes...
Applications of Wood Materials for Innovative Bridge Systems
