Filter by Keyword82 report(s) found with bridges in the keywords field The long-term objectives of this project were to develop and validate an instrumentation package for structural health monitoring of bridges subjected to overweight trucks and to develop plans for field deployment of the instrumentation on a pilot scale. Ultimately, the objective is to accurately correlate... This report evaluates two new glass-fiber reinforced polymer concrete reinforcement systems, which have been designed to serve as a non-corrosive alternative to steel reinforcement in reinforced concrete bridge girders. Due to the nature of the reinforcement geometry, these systems react in a way to... Simple-made-continuous (SMC) steel bridges are a relatively new innovation in steel bridge design. The SMC concept is a viable solution for steel bridges to recover market share of the bridges constructed in the United States. The majority of SMC bridges currently in use are constructed with concrete... This paper presents the results of an experimental study on the fatigue performance of RC beams strengthened with different externally bonded CFRP systems. Seven specimens were fabricated; three had no CFRP; the remaining four had one of two CFRP systems. The objective of this study was to determine... This report presents a research examining the feasibility of creating an integrated structural health monitoring and impact/collision detection system for bridges in remote cold regions, where in-person inspection becomes formidable. The research report includes a theoretical analysis of the impact event... The overall project is to demonstrate the effectiveness of shear spiking (technique already developed through a previous project). Many timber railroad bridges are deficient but it is too costly to replace them; hence, inexpensive repair techniques are needed. The proposed project will provide the necessary... As part of a study to develop design guidelines for integral abutment bridges, a study was undertaken in which the bridge movement of the 400 South Street Bridge was surveyed for one year to quantify changes in bridge movement due to temperature variations. These quantitative bridge movements were compared... Depending on the location, highway bridges can often support considerable amounts of traffic. Due to the limitations on current earthquake forecasting techniques, a normal amount of traffic will also typically remain on a bridge when an earthquake occurs. In addition to traffic, scour effects are also... Over the years, Fiber Reinforced Polymer (FRP) composites have gained popularity in transportation infrastructure as a material able to restore and increase the capacity of existing concrete elements. Properties such as a high strength to weight ratio, non-corrosive nature, durability, and high malleability... This report details the outcomes of shear spiking two open-deck, timber trestle railroad bridges and examining the effectiveness under applied loading. The bridges were made available to the researchers by the Union Pacific Railroad and were located in their Southern Region. The first site was located... |
