Filter by Keyword6 report(s) found with repairing in the keywords field 1 - 6 of 6 The first part of the study presents the time-dependent interfacial behavior of near-surface-mounted (NSM) carbon fiber reinforced polymer (CFRP) strips bonded to a concrete substrate using inorganic resins. Four types of bonding agents (mortar, polyester-silica, ultra-high performance concrete (UHPC)... This project studies effective configurations of self-centering devices in the seismic retrofit of curved bridges for control of longitudinal and lateral forces. Reparability of bridge columns is investigated experimentally. A seismic retrofit and repair technique using a Carbon Fiber Reinforced Polymer... Grouted Splice Sleeve (GSS) connectors are being considered for connecting bridge columns, footings, and pier caps in Accelerated Bridge Construction (ABC). A repair technique for precast reinforced concrete bridge column-to-footing and column-to-pier cap joints constructed with GSS connectors has been... This research study examined the effectiveness of the fiber reinforced polymer (FRP) spikes in repairing naturally damaged and deteriorated railroad bridge chords. Past research has shown that this process can be quite effective in improving the effective stiffness of railroad chord members that were... The present research suggests a new approach to the use of composite materials technology for repair of timber structural members. Due to the small aspect ratio of the typical railroad bridge span timbers, stiffness degradation can be related to decrease in the beam's shear performance. To rejuvenate... This report presents a brief historical overview of the development of expansive (shrinkage compensating) concrete. Three Utah Department of Transportation projects using expansive concrete are discussed as to the performance of the expansive concrete. On-site inspections were performed on three projects... |
