CCEER-14-05: Seismic Performance of Square Nickel-Titanium Reinforced ECC Columns with Headed Couplers
(2014-07-01)
Current bridge seismic design could be improved by moving towards performance based design to keep bridges operational and keep repair costs to a minimum by reducing damage to column plastic hinges and minimizing residual ...
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-00-7: A Comparison of Static and Dynamic Performance of Models of Flared Bridge Columns
(2000-10-01)
The main objective of this study was to explain the differences between the quasi-static and dynamic test results of two scaled models (HS and FA) of the columns in a bridge supported on reinforced concrete columns with ...
CCEER-98-6: Seismic Behavior of New Bridges with Skew and Curvature
(1998-10-01)
The following research examines the seismic behavior of bridges designed according to a new design configuration with reduced number of frames, equal column heights within frames, and hinges without hinge seats. Behavior ...
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-14-02: Performance-Based Probabilistic Damage Control Approach for Seismic Design of Bridge Columns
(2014-05-01)
Probabilistic seismic design is a relatively new concept for seismic design of bridges subjected to earthquakes. Through this method, uncertainties in seismic response and seismic demand are taken into account. The concept ...
CCEER-19-04: Shake Table Studies of a Steel Girder Bridge System with ABC Connections
(2019-04-01)
Accelerated bridge construction (ABC) reduces the onsite construction time by utilizing prefabricated elements. Connections between prefabricated elements are critical in high seismic areas to maintain the integrity of the ...
CCEER-03-7: A Study of Shape-Memory-Alloy-Reinforced Beams and Cubes
(2003-10-01)
Collapse and severe damage of reinforced concrete structures during strong
earthquakes has been a major concern for structural engineers. Current and past research
has been based on yielding steel reinforcement in order ...
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-92-1: Scale Model Testing of One-Way Reinforced Concrete Pier Hinges Subject to Combined Axial Force, Shear and Flexure
(1992-03-01)
This report presents the results of the second phase of an ongoing study at the University of Nevada, Reno. This phase involved laboratory and analytical evaluation of one-way reinforced concrete pier hinges subjected to ...
