Description
Rural transportation systems are of major importance to the nation's economy. Safety of rural bridges in many cases has deteriorated to a dangerous level rendering many avenues for the movement of goods and people to an unusable state. The recently developed glulam bridge system, composed of laminated stringers and deck fastened together by bolted and doweled connections, offers great potential in needed national bridge replacement programs.

Description
This study analyzes the effects of temperature change and thermal gradients on deck joint movement and provide recommendations regarding deck joint elimination. The data indicates that temperature shifts and thermal gradients through the depth of the girders along the joint are impacting the bridge's movements and causing changes in stress. A strong parallel is shown between the temperature changes and the study joint's movement and changes in stresses...

Description
CDOT currently uses FHWA's HEC-18 methods to estimate bridge-pier scour values. The FHWA equations was based largely on streams with uniform sediments, subcritical-flow conditions, and flatter gradients. In western states where many bridges cross steep mountain channels, bridge-scour equations are applied beyond the range of conditions for which they were derived. In this research study, a new bridge pier-scour equation has been developed suitable...

Description
The majority of Simple Made Continuous bridges currently in use are constructed with concrete diaphragms. This report presents the results of numerical analysis and laboratory testing of an alternative simple-made-continuous connection scheme that uses steel diaphragms in lieu of concrete diaphragms. A bridge using steel diaphragms was constructed by the Colorado Department of Transportation in 2005 serves as a basis for the research presented herein....

Description
The objective of this study is to determine if the development of a standardized subset of bridge plans s feasible and cost effective. The past 30 years of successful Colorado Department of Transportation bridge design can be used as a starting point to create a standardized subset of bridge plans.

Description
This study applies contract bid tabulations and element-level condition records to develop element-level actions, costs for actions, transition probabilities for models of deterioration of bridge elements, and transition probabilities for improvements to elements due to actions. The study uses transition probabilities for element deterioration to compute the number of years to possible loss of safety in bridges, and to compute the number of years...
