Financing Urban Transportation
New ways to finance urban transportation are needed. User fees are discussed, but in many cases users of urban transportation are the poor, including the elderly poor, who cannot afford...
Reconstruction Under Traffic: A Study of Some Effects of the Dan Ryan Project on Motor Carrier Operations in Northeast Illinois
The paper discusses preparations by the Chicago Area Transportation Study for a study of the operational responses of truckers to whatever effects upon the regional highway system are...
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...
Transmission Line Insulator Assembly Reliability
Transmission line insulator assemblies made up of ceramic or composite insulators and associated hardware are used to mechanically support and electrically isolate energized conductors...
Repair and Rehabilitation of Damaged Steel Flexural Members
In earlier years, the primary method for repairing steel flexural members was to replace the member. However, with the cost of labor and material increasing dramatically over the last...
The Fabrication and Erection of the Minneapolis Convention Center
A new convention center is part of the City of Minneapolis' successful plan to maintain an economically strong downtown core. It is the latest addition to a list of civic...
Double Angle Bracing Members
It has been pointed out that when a single line of bracing is used, the member is usually made from structural tubing. It has been suggested that when the loads are not too great, consideration...
Preliminary Design Considerations for Flat Deployable Structures
Deployable structures are prefabricated frames that can be stored in a compact configuration, and can be easily deployed into a large-span, load-bearing space structure. The interest in...
Some Examples of Latticed Structures in Spain
Since the middle of the last sixties latticed structures have extensively been used in Spain to cover different large areas as factories, churches, marketplaces, exhibition palaces etc....
Analysis of Tapered and Stepped Columns by Analogy to Cantilever Deflection
An analysis is developed for handling the buckling design of tapered and stepped columns with the aid of the so called 'amplification factors'. When these factors...
Design Issues in Steel Buildings
The Committee on Design of Steel Building Structures of the Committee on Metals of the Structural Division of ASCE was formed in 1981, with the express purpose of studying problems that...
BABE: An Expert System for Structural Design of Bridge Abutments and Piers
A knowledge-based expert system named 'BABE' (Bridge and Building Evaluation) has been developed for the purpose of helping the user in planning, analysis and...
Superquadric Object Representation for Dynamics of Multi-Body Structures
While the finite element representation of an object in terms of nodal coordinates and shape functions is ideal for representing the stress and energy state, it is not well suited to the...
Sulfur Polymer Concrete for Special-Purpose Applications
Special-purpose sulfur concrete construction materials, based on sulfur polymer cement (SPC) and mineral aggregate, have been developed by the U.S. Bureau of Mines as part of a program...
Concrete Lunar Bases
Scientific and industrial operations on the moon require suitably shielded structures. Small structures for limited scientific activities may be constructed from structural elements prefabricated...
Recent Development of Cement-Based Materials
Development of advanced techniques has enhanced the capability of more accurate characterization of engineering materials at both the microscopic and macroscopic levels. Through better...
Testing of Reinforced Concrete Bridges for External Reinforcement
Several continuous reinforced concrete slab bridges were constructed in the 1950's with spans ranging from 30 ft. to 60 ft. Longitudinal cracks were observed in the tension...
Fiber Composite Materials in an Arctic Environment
This paper summarizes a study on the behavior of light-weight structural composite materials in cold environments. Results are presented for two composite materials: fiberglass-epoxy and...
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...
Service Life of Underground Concrete Structures
The service life of underground concrete depends on both the physicochemical properties of the concrete materials and the properties of the in-service environment. The major factors controlling...
