This study presents the results of the most recent phase of laboratory research. The effects of support movements observed in the field test were examined by physical laboratory testing and computer-based structural modeling using AxisVM software [Inter-CAD. Kft, 2004]. The goal of this research was...

 

This research evaluates the effectiveness of hot-poured crack surfacing material and its ability to seal asphaltic cracks. The term "crack surfacing" is used to describe the rigidity of the material and to distinguish it from crack sealants. The University of Wyoming, in cooperation with the Wyoming...

 

Investigations into the effects of the addition of vertically-oriented shear spikes with fiberglass reinforced polymer rods have shown that the shear spikes increased the effective stiffness of the stringers of a full-scale timber bridge chord specimen. This was previously found to be true on dimension...

 

A testing facility for temporary longitudinal barriers was constructed at Colorado State University's Engineering Research Center which allows manufacturer's the opportunity to test their safety barriers prior to full-scale federal testing. This facility enables manufacturers to subject their products...

 

This report describes the results of examining the effects of weather exposure conditions on the connection details of the open deck timber trestle bridge. As an exploratory experimental study, the time dependent mechanical effects of moisture, temperature and humidity on a particular connection detail...

 

Research at Colorado State University in wood-concrete layered composites for structural applications has been in progress for more than a decade. Key features of the research are experimental and analytical work to analyze notched shear key interlayer connections. These connections are being used to...

 

Investigations into the effects Z-spiking with fiber reinforced polymer (FRP) rods have on the flexural stiffness and repair of deteriorated railroad crossties were conducted. These tests were conducted to provide a pilot study for an ultimate goal of repairing full-scale bridges. This report presents...

 
Highly Flexible Crash Barriers (Jun 2004, MPC-04-162)

A preliminary study modeling the nonlinear behavior of long, slender wooden members was conducted at Colorado State University for the purpose of their use in inexpensive, destroyable crash barriers. This preliminary study compared the results of physical test data, published exact solutions, and the...

 

A project to study the pier moment-rotation behavior of compact and non-compact high performance steel HPS70W bridge I-girders was conducted at Colorado State University in the context of examining two restrictions for inelastic design of steel bridge girders in the current edition of the AASHTO LRFD...

 

A variety of portable safety and security barriers for directing traffic (public events, sports facilities, etc.), and securing private and public locations against access (court houses, schools, etc.) have been developed. Some higher capacity systems have been developed for use on and around high speed...
