Structural Design of Container Cranes
The shipping industry uses container cranes to move cargo containers on and off ships. Container cranes have characteristics common to all crane structures, but many characteristics are...
Berthing Impact Force Distribution on Pile Supported Pier Structures
This paper investigates the degree to which a berthing impact force is distributed to the pile bents of batter pile supported pier structures. A procedure is developed to estimate the...
A Modern Cone Penetration Testing Vehicle
The geotechnical group at the University of Florida recently purchased a new insitu testing cone truck. This is a powerful, all wheel drive, off-the-road vehicle designed specially for...
Computer Assisted Pavement
In Rancho Palos Verdes, Calif. a 4,300 ft. long test installation of the Contained Rock Asphalt Mat (CRAM) Pavement System is expected to have a 50 year life. It cost a third less than...
Building a Bridge Within a Bridge
The City of Grand Rapids had to replace an aging bridge connecting vital commercial centers on opposite sides of Michigan's Grand River. The city's consultants...
Design of Impact Limiters for Waste Fuel Shipping Casks
Impact limiters are often used to control the decelerations experienced by a waste fuel shipping cask when it is subjected to the hypothetical accident condition loadings. Simplified design...
Truck Weight Enforcement on a WIM
Pavements on interstate highways and other major truck routes are deteriorating faster than predicted. The cause is largely the larger-than-predicted number of the heaviest, 5-axle trucks....
Ice Floe Impact Force on Vertical Sided Structures
A solution is described that does not assume a contact pressure-area curve or ice crushing strength. The impact force is related to Korzhavin's ice crushing equation by simple...
Ice Forces Due to Impact Loading on a Sloping Structure
Two approximate methods are presented for determining Dynamic Magnification Factors due to floe impact on sloping structures. Some of the physical processes involved are treated simplistically,...
Response of Concrete Shell Panels to Simulated Impact
Concrete gravity structures have been constructed in Arctic regions for oil and gas exploration/production. In addition to extreme winds and waves, sheet ice, annual ridges, rubble fields,...
Operations Improvement through Product Evaluation
Transit Managers today are involved in a battle to maintain the quality of their systems. This paper takes a close look at several problems and then suggests a cure that can be effective...
Modeling Streamflow Response from Minnesota Peatlands
A deterministic, continuous simulation model was developed to predict the effects of peatland development on streamflow. The Peatland Hydrologic Impact Model is largely physically based...
Vehicle Sound Power measurement Using the Acoustic Intensity Method
The use of the two microphone Acoustic Intensity Method of obtaining accurate measurement of over-all sound power of large wheel loaders is described. This system is in operation, within...
The Role of Nonprofits in Coastal Conservation
The California State Coastal Conservancy's Nonprofit Organization Assistance Program is a unique vehicle through which private land trusts and other nonprofits have become...
Effects of Perturbations on South Padre Island
The types, extents, and durations of perturbations affecting the ecological zones of South Padre Island are assessed. Emphasis is placed on providing the environmental documentation necessary...
Stress and Strain Responses of a Soil-Pipe System to Vehicular Traffic
A 16-in. natural gas pipeline near Racine, Wisconsin, had been in service for some 30 years. In 1982 road widening operations on a line parallel with the pipe presented the opportunity...
APM System Performance and Guideway Design Parameters
Automated People Movers (APM) are a relatively new form of transportation system becoming popular over the last twenty to twenty-five years. They are characterized by fully automatic and...
Standardization of AGT Systems in Japan
Automated guideway transit systems (AGT) have been developped by different private firms in Japan, and therefore, the system components and dimensions are somewhat diversified. Such diversity...
Lille DPM System & VAL Family
This document provides a brief description of the different steps from the beginning to the total completion of the Lille downtown people mover (DPM) program in France. The system performance...
Development and First In-Service Use of Automatic People Movers in the Federal Republic of Germany, with Special Reference to the Magnetic Levitation System M-Bahn
People movers have been under development for the past 14 years in the Federal Republic of Germany. Of the four systems developed, two have been put into service. One of the two successful...
