TRACK(1.0): A Railroad Track Design and Evaluation Computer Program for Work Planning and Budgeting
This paper describes TRACK, a track structural analysis method and computer program developed by the U.S. Army Construction Engineering Research Laboratories. TRACK is a program for evaluating...
Airfield Pavement Management System
This paper describes a comprehensive Pavement Management System (PMS implemented at 24 airports in the kingdom of Saudi Arabia. The PMS development and implementation was completed in...
Automated Generation of NBI Reporting Fields from Pontis BMS Database
Methods to generate National Bridge Inventory (NBI) condition ratings for deck (Field 58), superstructure(Field 59), substructure (Field 60) and culvert (Field 62) from the bridge database...
Large Truck Impacts on the Highway Infrastructure: The Bridge Dimension
Recent U.S. studies have explored the productivity gains of longer combination vehicles (LCV's) and their impacts on highway infrastructure. The area least explored is LCV operations and...
Managing a Bridge Program for Scour
Recent events have focused national attention on the need for States to implement a managed program to determine the scour vulnerability of each of its bridges. Since 85% of all bridges...
Fuzzy Sets Model for Evaluation of Bridge Projects
This paper presents the formulation of a computerized decision support system that would aid the bridge engineer in long range planning of bridge funding needs, specially, to select the...
An Application of Scour Hazard Analysis and Management
A phased study for the assessment of bridge scour vulnerability is presented. Its objectives are to: (a) initiate a field assessment program, (b)establish data handling capabilities, (c)...
Maglev Guideway Route Alignment Parameters
Passenger comfort at high maglev vehicle speeds (110 to 134 meters per second) has significant impact on the proposed use of the existing highway and railroad rights-of-way for hosting...
The Force Between a Bogie and a Troubled Suspension and Guidance Coil
It is very important for the superconducting LSM Maglev vehicle to maintain the safety. Currents induced in suspension and guidance coils arranged on the side wall of a guide way generate...
High Speed Rail Loading Scenario and Dynamic Tuning of Track
Similarities and differences exist between conventional and high speed rail (HSR) infrastructure design. The differences stem from the dynamic nature of the HSR loading scenario and the...
Aerodynamic Resistance of Trains Running Through a Tunnel
In what follows, some previously published results and formulae have been combined in order to obtain an applicable tool for evaluating the energy consumption of trains in tunnel as a...
The Use of Multibody Software in the Wheel/Rail Contact as Applied to Very High Speed Tests
How strange may it be, the behaviour of railway vehicles depend on contact forces developing between wheels and rails inside patches of no more than 1 cm2....
Assessment of Guideway Systems for Maglev Applications
Recognizing the potential benefits of MAGLEV high speed mass transportation systems, three innovative guideway systems have been evaluated herein from the viewpoint of: (1) loads and performance...
Lifelike Model
Data from about 400 structures in the San Francisco Bay Area were recorded during the 7.1 Richter-scale Loma Prieta quake. Among these structures was a 49-story office tower in downtown...
