Java Applets for Analysis of Trusses, Beams and Frames
(Virginia Tech, 1998-07-27)
Java applets are developed to assist in the learning of basic structural analysis concepts. In order for these programs to be easily available over the Internet, they are written in the object-oriented Java programming ...
Effect of Spatial Scale on Hydrologic Modeling in a Headwater Catchment
(Virginia Tech, 1999-01-29)
In this study, two hydrologic models were applied to the mountainous Back Creek catchment, located in the headwaters of the Roanoke River in Southwest Virginia. The two models employed were HEC-1, an event based lumped ...
Three-Dimensional Nonlinear Dynamics of a Moored Cylinder to be Used as a Breakwater
(Virginia Tech, 1999-04-05)
A three-dimensional, nonlinear dynamic analysis
is conducted on a fully submerged, rigid, solid
cylinder to be used as a breakwater. The breakwater
could potentially be used as a single cylinder to
protect small ...
Investigation of Steel Joist Supported Wood Floor Systems
(Virginia Tech, 1997-02-01)
This study investigates four aspects associated with steel joist supported wood floor systems: 1) acceptability, 2) prediction of deflection, 3) prediction of frequency, and 4) effects of diagonal bracing. Six full scale ...
Determination of Optimum Tack Coat Application Rate for Geocomposite Membrane Use in Roads and Overlaid Bridge Decks
(Virginia Tech, 1999-11-18)
Two critical components of the United States civil infrastructure, bridges and roads, have deteriorated in the past two decades at an accelerated rate and are in need of maintenance and rehabilitation. Geosynthetics may ...
Three-Dimensional Analysis of Moored Cylinders Used as Breakwaters
(Virginia Tech, 1997-12-05)
For oblique and normal water waves at various frequencies, the use of moored cylinders as breakwaters is considered numerically using linear three-dimensional analysis. The breakwater can be used by itself for protection ...
A Load-Deflection Study of Fiber-Reinforced Plastics as Reinforcement in Concrete Bridge Decks
(Virginia Tech, 1997-05-05)
Approximately fifty percent of the bridges in the United States are considered deficient. The deterioration of the concrete components is a leading cause of the problem. The deterioration of concrete bridge decks is due ...
Assessing Urban Non-Point Source pollutants at the Virginia Tech Extended Dry Detention Pond
(Virginia Tech, 1997-05-23)
With a growing concern for the environment and increasing urbanization of rural areas, understanding the characteristics of urban non-point source pollution has become a focus for water quality investigators. Once thought ...
Effective Lengths of Web-Tapered Columns in Rigid Metal Building Frames
(Virginia Tech, 1997-05-27)
Current procedures for estimating effective length factors for web-tapered members rely heavily on the use of charts and graphs. This makes them difficult to implement using a computer. In addition, they are often based ...
Measuring the Effects of a Step Change in the EPC Process
(Virginia Tech, 1998-01-20)
Strategic procurement items, including complex engineered equipment and systems essential for project performance, are frequently designed, manufactured, and delivered by suppliers who are outside the circle of cooperation ...
