Recommendations for the Connection Between Full-Depth Precast Bridge Deck Panel Systems and Precast I-Beams
(Virginia Center for Transportation Innovation and Research, 2007-06-01)
Precast bridge deck panels can be used in place of a cast-in-place concrete deck to reduce bridge closure times for deck replacements or new bridge construction. The panels are prefabricated at a precasting plant providing ...
Flexural Strength of Exterior Metal Building Wall Assemblies with Rigid Insulation
(Virginia Polytechnic Institute and State University, 2011-08-01)
The goal of this research study is to observe and quantify the influence of rigid board insulation on through-fastened girt capacity. Rotational restraint tests are performed to study local rotational stiffness at the ...
Design Optimization Of Slotted Waveguide Antenna Stiffened Structures (Swass)
(2014-04-15)
The objective of the research is to investigate computational methods for design optimization of a Conformal Load-Bearing Antenna Structure (CLAS) concept. Research centers on investigating computational methods for design ...
Construction of a Virginia Short-Span Bridge with the Strongwell 36-Inch Double-Web I-Beam
(Virginia Center for Transportation Innovation and Research, 2005-10-01)
The Route 601 Bridge in Sugar Grove, VA, spans 39 ft over Dickey Creek. The bridge is the first to use the Strongwell 36-in-deep fiber-reinforced polymer (FRP) double-web beam (DWB) in a vehicular bridge superstructure. ...
Proof Testing a Bridge Deck Design with Glass Fiber Reinforced Polymer Bars as Top Mat of Reinforcement
(Virginia Center for Transportation Innovation and Research, 2003-06-01)
The primary objective of this project was to test a full-scale prototype of a bridge deck design containing glass fiber reinforced polymer (GFRP) bars as the top mat of reinforcement. The test deck mimics the design of the ...
Native Backfill Materials for Mechanically Stabilized Earth Walls
(Virginia Center for Transportation Innovation and Research, 2005-04-01)
Mechanically stabilized earth walls are an attractive alternative to conventional reinforced concrete retaining walls. The economy of these walls for non-critical applications might be improved by using alternative backfills ...
Grade 300 Prestressing Strand and the Effect of Vertical Casting Position
(Virginia Center for Transportation Innovation and Research, 2009-09-01)
The purpose of this investigation was (1) to compare the differences in the transfer length, development length, and flexural strength among Grade 300 strand, the traditional Grade 270 strand, and the predictions of these ...
Classification of longitudinal welds in an aluminum bridge deck
(Virginia Center for Transportation Innovation and Research, 2002-02-01)
An aluminum bridge deck (called ALUMADECK) has been developed by Reynolds Metal Company and is made of extruded aluminum sections welded together at the sides to form a bridge deck. The longitudinal welds used to connect ...
Plate & tube bridge deck evaluation in the deck test bed of the Troutville, Virginia, weigh station
(Virginia Center for Transportation Innovation and Research, 2004-03-01)
This report addresses the laboratory and field performance of multi-cellular fiber-reinforced polymer (FRP) composite bridge deck systems. We focus specifically on FRP decks produced from adhesively bonded pultrusions where ...
System Synthesis Supplementary Data
(Virginia Tech, 2018-02-22)
Introduction
In order to explore the capability of automated system synthesis to compose a variety of novel systems from a common set of components, an experiment simulating the design of a mobile search and rescue ...
