Probabilistic Post-Liquefaction Residual Shear Strength Analyses of Cohesionless Soil Deposits: Application to the Kocaeli (1999) and Duzce (1999) Earthquakes
(Virginia Tech, 2005-10-07)
Liquefaction of granular soil deposits can have extremely detrimental effects on the stability of embankment dams, natural soil slopes, and mine tailings. The residual or liquefied shear strength of the liquefiable soils ...
Live Load Testing of Appalachia, Va Concrete Arch Bridges for Load Rating Recommendation
(Virginia Tech, 2012-09-13)
As Americaâ s infrastructure ages, many of the nationâ s bridges approach the end of their service life. In order to develop a method for handling the rising number of deficient and functionally obsolete bridges, ...
Internal Damping Rates of Construction Cranes
(Virginia Tech, 1997-05-27)
The conveyance of payloads by construction cranes generates pendulations of the payload. This research provides a critical design parameter for the development of a device that aids in reduction of these pendulations. Previous ...
Quantifying the Relationship Between Skid Resistance and Wet Weather Accidents for Virginia Data
(Virginia Tech, 2004-09-13)
One of the factors contributing to motor vehicle crashes is lack of sufficient friction at the tire-pavement interface. Although the relationship between surface friction and roadway safety has long been recognized, ...
Development of Standard Geodatabase Model and its Applications for Municipal Water and Sewer Infrastructure
(Virginia Tech, 2010-02-03)
Availability of organized data is required for accurate prediction of structural or functional deterioration in sewer and water pipes. Toward this end, GIS provides a means for viewing, understanding, interpreting, and ...
Capacity Modeling of Freeway Weaving Sections
(Virginia Tech, 2005-05-09)
The dissertation develops analytical models that estimate the capacity of freeway weaving sections. The analytical models are developed using simulated data that were compiled using the INTEGRATION software. Consequently, ...
The Investigation of Transverse Joints and Grouts on Full Depth Concrete Bridge Deck Panels
(Virginia Tech, 2009-12-08)
A set of experimental tests were performed at Virginia Tech to investigate transverse joints and blockouts on full depth concrete bridge deck panels. The joints were designed on a deck replacement project for a rural three ...
Feasibility Study of Partially Restrained Connections
(Virginia Tech, 1997-02-10)
In recent years the idea of using partially restrained connections in building structures has become more practical and economical. Partially restrained connections resist moment and also allow ...
A comparative study of weaving sections in TRANSIMS and Highway Capacity Manual
(Virginia Tech, 2001-06-28)
Weaving is defined as the crossing of two or more traffic streams traveling in the same direction along a significant length of the highway without the aid of traffic control devices. The traditional methods used for the ...
Optimal forms of rectangular-base, shallow shells with respect to buckling
(Virginia Polytechnic Institute and State University, 1985)
