CCEER-13-01: Instrumentation and Dynamic Characterization of the Galena Creek Bridge
(2013-01-01)
The Galena Creek Bridge is a concrete arch bridge that was completed in 2012 as part of the I-580 freeway in Northern Nevada. The research in this report covers the instrumentation and in–field experiments conducted to ...
CCEER-12-03: Seismic Performance of Circular and Interlocking Spirals RC Bridge Columns under Bidirectional Shake Table Loading Part 1
(2012-08-01)
Under seismic excitations reinforced concrete bridge columns (RCC) are subjected to combinations of forces and deformations. These complex actions are caused by spatially-complex variation of earthquake ground motions, the ...
CCEER-95-3: Ductility of Rectangular Reinforced Concrete Bridge Columns with Moderate Confinement
(1995-07-01)
This study is part of a project to develop detailing guidelines for reinforced concrete bridge columns and walls in areas of moderate seismicity. The research examined the ductility and behavior of rectangular reinforced ...
CCEER-04-6: Seismic Performance of RC Bridge Columns Reinforced with Two Interlocking Spirals
(2004-08-01)
Interlocking spirals are used in bridge columns not only because they provide more effective confinement than rectangular hoops but also because interlocking spirals simplify the column fabrication. The behavior of columns ...
CCEER-15-02: Post-Tensioning Duct Air Pressure Testing Effects on Web Cracking
(2015-01-01)
Nevada Department of Transportation (NDOT) post-tensioned concrete bridges have experienced web cracking near the post-tensioning ducts during the construction process. The ducts were air pressure tested to ensure the duct ...
CCEER-18-02: Improving the Long-Term Performance of Bridge Decks using Deck and Crack Sealers
(2018-05-01)
Many bridges are exposed to snow and ice during the winter. As snow and ice accumulate over the bridge’s concrete deck, deicing salts are usually spread on the bridge deck to remove and dissolve the snow and ice. Deicing ...
CCEER-99-3: Seismic Response of Bridge Pier Walls in the Weak Direction
(1999-04-01)
The research presented in this report consisted of an experimental and an analytical study. The objective of the experimental study was to evaluate the out-of-plane seismic behavior of representative bridge pier walls that ...
CCEER-00-4: Dynamic Testing of Non-Prismatic Reinforced Concrete Bridge Columns Retrofitted with FRP Jackets
(2000-01-01)
This document presents the development and experimental validation of seismic retrofitting of non-prismatic (flared) reinforced concrete bridge columns. Fiber reinforced plastic (FRP) jacketing was installed on the ...
CCEER-06-01: Development of a Seismic Design Method for Reinforced Concrete Two-Way Bridge Column Hinges
(2006-02-01)
Two-way hinges are commonly used in bridge columns to reduce column moment transfer to foundation. Currently the shear capacity of two-way hinges is determined using the shear friction method. When subjected to lateral ...
CCEER-08-02: Seismic Time History Analysis and Instrumentation of the Galena Creek Bridge
(2008-04-01)
The behavior of complex and irregular structures during construction and in a seismic event is often not well understood by practicing design engineers. The focus of this research is centered around a comprehensive examination ...
