Development Of Anchorage System For Frp Strengthening Applications Using Integrated Frp Composite Anchors, Geoffrey N. Mcguirk
Development Of Anchorage System For Frp Strengthening Applications Using Integrated Frp Composite Anchors, Geoffrey N. Mcguirk
Masters Theses 1911 - February 2014
Over the past three decades the use of externally bonded fiber reinforced polymer (FRP) materials for structural strengthening applications has become an accepted and widely used method. A primary concern of FRP structural strengthening systems is that the FRP often debonds from the concrete well before the load capacity of the FRP material is reached. In addition, debonding failures are often brittle and occur with little warning. Past research concluded that fastening FRP sheets with FRP anchors is an effective method for delaying or preventing debonding failures. However, there is a clear lack of research pertaining to fastening FRP sheets …
Historic Bridge Evaluation Using Finite Element Techniques, Helena M. Charron
Historic Bridge Evaluation Using Finite Element Techniques, Helena M. Charron
Masters Theses 1911 - February 2014
The present study examined the application of modern, computer-based analysis methods to two existing historic bridges in Massachusetts. The first bridge featured in this study is the Woronoco Bridge, a reinforced concrete open spandrel arch bridge that was constructed in 1923. It was hoped that a computer-based, parametric study of this bridge would prove it to be deck-stiffened, similar to select bridges of Swiss engineer Robert Maillart. However, the results do not support that there was any intent to reduce bending in the arch as a result of increasing the stiffness of the bridge deck. Instead, the Woronoco Bridge appears …
Enhancing Concrete Barrier Reflectivity With A Focus On Recycled Glass Aggregate Replacement, Regina Shklyan
Enhancing Concrete Barrier Reflectivity With A Focus On Recycled Glass Aggregate Replacement, Regina Shklyan
Masters Theses 1911 - February 2014
Increased accident rates during the nighttime and wet weather conditions on the United States highways necessitate the enhancement of highway concrete barrier visibility. The visibility of these delineators is dependent on their reflectivity. Several methods are proposed that stand to increase the reflectivity of these concrete barriers, such as the use of white cement versus gray cement and the attachment of raised pavement markers to the side of the barriers. The incorporation of recycled glass into the concrete mixture is one of the proposed methods that was put through further laboratory study. The aim of the laboratory testing was to …
