Ropeway Material Handling Systems for Lunar Mining Sites
The establishment of permanent lunar sites will be a requirement for future space explorations during early missions into space as well as long term. During all stages it will be necessary...
Principles of Control for Robotic Excavation
Excavation can be considered one of the most unstructured problems in the construction environment. On one hand, many technologies have been developed in the past to build shelters using...
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...
Pre-Compression of Concrete Breasting Dolphins Solves Construction Problem
A roll-on/roll-off ferry terminal was built in Quincy, Massachusetts in 1989 as part of a marine transportation system to support construction of the sewage treatment facilities proposed...
Validation of the SEADYN90 Cable Simulation Model Using a Three-Dimensional Cable Deployment Data Set
This paper presents data from a full-scale, three-dimensional cable payout test and the corresponding numerical simulations using the SEADYN90 computer model. The experiment, which was...
Fiber Ropes for Ocean Engineering in the 21st Century
Recent advances in synthetic fiber ropes will greatly influence the practice of civil engineering in the oceans during the 21st Century. New fibers have moduli almost as high as steel...
The Great Chicago Flood of 1992
In April of 1992, a breach in a freight tunnel caused the river that flows through Chicago to pour into city building basements, causing the city to shut down. Critical utility systems...
Tensile Terminal
Few can miss a fabric roof that covers a 1.45 million sq ft area. The one covering the Denver International Airport's Landside Terminal complex (reportedly the nation's...
Tying Back a Landslide
A slope covered with landslide debris is never the most desirable site on which to build, but sometimes it is the only one available. For the Forks of Butte hydroelectric power project,...
Cables and Anchorages
The following types of cables are generally used in cable stayed bridges: Parallel bars; Parallel seven wire strands; Parallel or semi-parallel wire cables; Locked coil strands and ropes;...
Stability of Cable-Stayed Brides
This chapter deals only with stability under static loadings. For aerodynamic stabilities and stability of structure under seismic loading, see the appropriate chapters. Both the towers...
Special Considerations for Railroads
In comparison with highway bridges, railroad bridges are generally characterized by a larger ratio between traffic and dead load, larger braking forces, smaller relative width of the bridge...
Seismic Design
For seismic design of cable-stayed bridges, the following characteristics are of importance: The cable-stayed bridges consist of various components with different structural properties;...
Rebuilding an Illusion
A dam that controls the level of Fall Lake, a major entry to the Boundary Waters Canoe Area Wilderness of northern Minnesota had to be rebuilt, but federal agents barred constructors from...
White Steel for Osaka Bay
Wind, earthquake and aesthetics were the design determinations for Japan's Higashi-Kobe Bridge. The designers also had to consider the man-made bay infill site and a directive...
Advanced Composites Materials in Civil Engineering Structures
This proceedings of the Specialty Conference on Advanced Composites Materials in Civil Engineering held in Las Vegas on January 31?February 1, 1991 contains 40 papers from ten technical...
Beyond Engineering: The Politics of Maracaibo
The Lake Maracaibo Bridge in Venezuela was built in 1959. It ranks as one of the largest and longest bridges in the world at the time it was built and contained the longest concrete cable-stayed...
An Analysis Procedure for Cable Structures Using an Isoparametric Finite Element
The computer modeling and analysis of cable structures creates a major problem for the analyst in that the geometry of the cables is dependent on analysis results. The purpose of this...
Hydrodynamics of Deepwater Tension Leg Platforms
A model is presented for investigating the overall quasi-static behavior of tethers, the anchoring elements for a Tension Leg Platform, TLP. Effects of tether weight and curvature, and...
Dynamic Behavior of a Non-Linear Cable Truss
The equations of motion of a geometrically non-linear cable truss are presented. The behavior of the truss subject to harmonic excitation is studied....
