Secondary Member Contribution to the Behavior of Damaged Multigirder Highway Bridges
This paper examines the effects of secondary members (cross bracing and diaphragms) on the prediction of the response of damaged simple span steel multigirder bridges. Extensive analytical...
The Application of Gauss Numerical Integration Method in Arch Dam Trial-load Method Program
The characteristics of Gauss Numerical Integration Method are the unequal distance between nodes and fairly high accuracy. When the number of nodes is n, the algebraic accuracy can be...
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...
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...
Colorado Dome
Innovative engineering and precise design helped engineers overcome a building's unique shape and difficult site to deliver the $71.5 million Jefferson County Government Center...
Coastal Erosion and Protection in China
The recent coastal erosion in China was becoming increasingly remarkable in the late fifties and had taken a turn for the worse in the late seventies. At present there exist about 70 per...
Meteorological Forcing on Louisiana Wetlands
The open wetland areas of southern Louisiana are vulnerable to meteorological forcing. On the basis of over one year U.S.G.S. funded measurements of atmospheric pressure, air-sea temperature...
Are Landscape Patterns Related to Marsh Loss Processes?
Marsh loss that occurs in Louisiana is seldom associated with shoreline erosion of lakes and bayous; instead, marshes break up internally. Marsh loss is attributed to processes that stress...
Consolidation Settlement Potential in South Louisiana
Primary consolidation is an important cause of wetland loss in active and recently abandoned deltaic plains in south Louisiana. Argillaceous and organic facies are most subject to reduction...
Dealing with TMDLs in the Dairy-McKay HUA
The maximum phosphorus concentration for the TMDL in the Tualatin River is set by Oregon Administrative Rules (OAR) at 0.07 mg/1, Dairy-McKay Creek is 0.045 mg/1 Identification of potential...
Marina Facilities Planning Design and Operations in Hurricane Prone Areas
The overall growth in population of coastal areas in the southeastern and coastal regions of the Unites States has created a need for additional water related recreation facilities such...
Anthropogenic Activities Affecting Sediment Load Balance Along the West African Coastline
The west African coastline stretches from Senegal in the west-to Cameroon in the east. This coastline had naturally over time received most of its sediments through the numerous rivers...
Fish Resources of Coastal Waters of the Gulf of Guinea: Natural and Man-Made Factors Influencing their Distribution, Abundance and Capacity for Development and Sustained Exploitation
The Gulf of Guinea corresponding to Equatorial West Africa is bordered by eleven coastal states from Cote d'Ivoire in the west to Gabon in the South. Its coastal waters have no less than...
Lag Relations for Semi-Arid Regions and Urban Areas
The use of synthetic unit hydrographs often requires the estimation of lag or other travel time parameters. Several procedures are available for estimating such unit hydrograph parameters....
Infiltration into Thick Unsaturated Alluvial Deposits: A Preliminary Study
An infiltration and dye transport study in an unsaturated alluvial deposit was conducted using a square flooding type infiltrometer over a 50 hour period. Red and blue dyes were added...
