Database for Pipeline Bridges in North America
Work began in 1985 at Wayne State University on a research study of pipeline suspension bridges. This effort, which was funded by ANR Pipeline Company of Detroit, Michigan, investigated...
Plastic Potential
Some 220,000 tons of epoxy-coated steel has been used in the construction of bridge decks since 1987, but some have raised questions about its long-term durability. New materials for prestressing...
Use of CLSM Fly Ash Slurry for Underground Facilities
This paper presents the results of research performed in developing and using flowable fly ash slurry which falls under the classification of Controlled Low Strength Material (CLSM) as...
Active Guideway Systems
Many automated people movers which have been developed or studied in France or in other countries belong to the category of active guideway systems. This paper describes characteristics...
Providing People-Mover Access for the Getty Center
An Otis People-Mover System was selected by The Getty Trust to transport visitors to The New Getty Center Museum for the Arts from an entry parking area up a steep hillside to the museum...
Narita Airport People Mover System
This paper gives a general overview of the People Mover installed at the Narita Airport by Otis Elevator in 1992. Included is a description of the unique combination of a cable propelled...
New Opportunities Offered by Cable Systems

Keeping Cables Calm
Cable vibration and corrosion are potential problems relating to cable-stayed bridges. Nonetheless, owners think their structural elegance is worth it, and increasingly longer cable-stayed...
A Dome To Remember
Under intense pressure from all sides, a trio of engineering and architectural firms working in San Antonio, Tex., turned the political coal of a stadium everyone wanted to build (but...
Dams Going Safely over the Top
Many older dams can't pass updated design floods without overtopping the embankment crest. Conventional upgrade methods, enlarging spillways or raising crests, are expensive....
Double Diamonds: New Brand for a Texas Bridge
Double diamond towers, distinctive as a cattle brand but tall as a 44 story building, have reached landmark status on the Texas Gulf Coast even though the bridge they will carry won't...
Design Cable-stayed Bridge for Cost Effectiveness and Safety
Innovative design approach is needed to enhance the prestigious status enjoyed by cable-stayed bridges. The present paper aims at such a goal of cost effectiveness and safety by providing...
Wind Cross-Spectrum Effects on Long-Span Bridges
This paper discusses current analysis for long span bridge response based on wind components. The authors summarize the development of techniques which take such components into account,...
Inflatable Structures of Non-Circular Cross Section
This paper discusses six approaches to achieve an inflatable structure of non-circular cross section for use in lunar base development. Other papers have examined potential multiple uses...
Tensile-Integrity Structural Concepts for the Lunar Surface
This paper suggests the use of tension cable structures of a particular type, Tensegrity structures, for a lunar base. Tensegric shells can be a system of bars and cable net. The shell...
Tripod Crane Concept for Lunar Surface Construction
A construction scheme using three integrated cranes is proposed. Mikulas proposed a lunar crane concept which introduces a set of three cables in order to stabilize the payload. This paper...
Cables and Cranes for a Flexible Lunar Transportation System
This paper will discuss the results of preliminary research on a cable-based transportation system for the moon. The paper will address the principles of cableway design and will present...
