Preliminary Investigation of a Lunar 16 Meter Optical Telescope
The results of a year-long effort to develop a design concept for the structure of a 16 meter lunar optical telescope are presented. Various mounting configurations and mirror configurations...

Internal Pressure in a Lunar Inflatable Structure
Design and construction of a structure on the Moon requires addressing a host of issues not encountered on Earth. A critical design factor is the internal atmospheric pressure necessary...

Design Considerations for Multi-Wheel Aircraft
The available test data for performance of flexible pavements were analyzed using the Boussinesq and elastic layered theories. It was shown that strain criteria could be developed for...

Denver International Airport Fabric Roof Design
The design of Denver's Landside Terminal Complex for the new Denver International Airport, called for some far reaching vision coupled with imaginative building technologies. Because of...

The Design of the Airside Concourses
The growth of commercial air traffic in the United States has resulted in the development of the 'New Denver International Airport.' the airside concourses were designed by joint venture...

The Airport Traffic Control Tower for the New Denver International Airport
Developing a new airport traffic control tower involves many complexities of planning, engineering, and coordination. For the ATCT at the New Denver International Airport, these complexities...

Using Traffic Network Models to Assess Site Impact Traffic
This paper covers experience gained in using traffic network models as a site traffic analysis tool, including problems encountered in developing an appropriate zone system and coded highway...

Using Computer Models in Site Impact Assessment
Use of comprehensive large area traffic models (citywide or regional) in site traffic impact assessment can greatly aid certain elements of the analysis, but may be inappropriate for other...

Development Impact Assessment with Transportation Models
The use of microcomputers in urban transportation modeling is having a major impact on the traffic engineering and planning profession. Between the late 1950's and early 1980's, most modelling...

Modeling Nearshore Currents in the Vicinity of the Endicott Causeway, Alaska
The Endicott Causeway connects two oil production islands on the southern side of Stefansson Sound, about 5 km offshore of the Sagavanirktok River delta, to the mainland of the Alaskan...

Impact of Breakwater Removal on Hydrodynamics and Water Quality in Flushing Bay, New York
Hydrodynamic and water quality models were used to simulate the potential effect of removing a breakwater to increase flushing and improve water quality in Flushing Bay, New York City....

Nondestructive Testing of Concrete Elements and Structures
Quality of a concrete structure depends on good construction practice. On the other hand, continuous repair and maintenance preserve the quality of construction. Nondestructive evaluation...

The Future Role of Factory Built Housing
For most of this century, and particularly around 1970 as epitomized by Operation Breakthrough, the concept of transitioning the US housing industry from stick-by-stick field building...

Customer Requirements in Industrialized Housing
Residential construction efforts in the U.S. are highly fragmented, and this has slowed the application of new technologies. While there has been an increase in the use of manufactured...

Computer Modeling of Structural Systems for Residential Scale Buildings
The majority of housing in the United States is single family residences or low-rise multiple family dwelling units. The structural systems usually consist of rather uncomplicated types...

System Engineering and Risk
System engineering means many things to many people, but there is a large group of practicing engineers in the defense and energy sectors who define system engineering as a structured...

Optimal Allocation of Resources in Repair and Maintenance of Bridge Structures
The structural design process, examined in its entirety (and taking into account the uncertainty and randomness that characterize the governing parameters) is a decisional process, involving...

Linearisation and Offshore Fatigue Reliability
In determining the force effects due to wave action on offshore structures it is conventional to use an equivalent linearisation to convert wave velocities to forces via Morison's equation....

Reliability Analysis of Lunar Structures Under Meteoroid Impact
The United States is slowly moving towards lunar base, and possibly Mars base, activities. Design of structures for these bases requires knowledge about loadings and conditions which in...

Probabilistic Analysis of Post-Tensioned Steel Girder Bridges
External post-tensioning is used as a means of strengthening existing steel girder bridges. Since absolute safety of structures is impossible to attain due to uncertainty in load and resistance,...
