Rapid Bridge Replacement: Processes, Techniques, And Needs For Improvements, Yong Bai, William R. Burkett
Rapid Bridge Replacement: Processes, Techniques, And Needs For Improvements, Yong Bai, William R. Burkett
Civil and Environmental Engineering Faculty Research and Publications
The terrorist attack on September 11, 2001 and subsequent potential threats to the United States transportation systems have presented an urgent need to develop emergency response plans in order to quickly react to the possible consequences of an extreme event. Highway bridges, as critical components of the nation’s transportation network, have received increased attention. To respond to the potential threats on highway bridges, a research project was conducted to identify rapid bridge replacement processes, techniques, and needs for improvements. To achieve the research objectives, the research team studied three cases of previous bridge replacements following extreme events. By studying these …

Study Of Same-Lane And Inter-Lane Gvw Correlation, Colin C. Caprani, Bernard Enright, E. J. O'Brien
Conference papers
Extensive work has been done over the last two decades on the simulation of traffic loading on bridges. The methodology used is to generate a number of years of simulated traffic and to use extreme value statistics to predict more accurately the characteristic loading for a given bridge. The parameters and probability distributions used in the Monte Carlo simulation must be based on observed sample traffic data. Some previous studies have made unsubstantiated assumptions regarding correlation between the Gross Vehicle Weights (GVW) of trucks in the same lane, or between trucks in adjacent, same direction lanes. For this paper, an …

The terrorist attack on September 11, 2001, and subsequent potential threats to U.S. transportation systems have presented an urgent need to develop emergency response plans to quickly react to the possible consequences of extreme events. Extreme events include terrorist attack as well as man-made and natural disasters such as explosions, fires, floods, and earthquakes. The objective of this research was to identify strategies and technologies to quickly restore the use of highway bridges, a critical component of the nation’s transportation network, in case they are damaged or destroyed by extreme events. One of the tasks associated with this research was …

Liquefaction Effects On Lateral Pile Behavior For Bridges, Wei Zheng, Ronaldo Luna
Liquefaction Effects On Lateral Pile Behavior For Bridges, Wei Zheng, Ronaldo Luna
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
A coupled pile-soil-structure interaction (SPSI) analysis method is presented to study the liquefaction effects on lateral pile behavior of the highway bridges. Pile-soil interaction is simulated by the dynamic nonlinear p-y method including the effect of liquefaction. The liquefaction effects to the pile-soil interaction are taken into account by introducing a degradation multiplier to the p-y curve. The degradation multiplier is related to the excess pore water pressure buildup at the pile-soil interface. The SPSI analysis method is implemented into a Missouri highway bridge site near the New Madrid Seismic Zone (NMSZ) rift complex for future earthquake scenarios of Mw …
Implementation Of A Non-Metallic Reinforced Bridge Deck, Volume 2: Thayer Road Bridge, Robert J. Frosch, Ali Cihan Pay
Implementation Of A Non-Metallic Reinforced Bridge Deck, Volume 2: Thayer Road Bridge, Robert J. Frosch, Ali Cihan Pay
JTRP Technical Reports
The primary maintenance problem with bridges in Indiana has been deterioration of the concrete deck which is often related to corrosion of the reinforcing steel. While a corrosion protection system consisting of epoxy-coated reinforcement in combination with 2-1/2 in. of Class C concrete cover has been used in Indiana, research and experience have demonstrated that this system can be compromised. As an alternative solution to the corrosion problem in reinforced concrete, fiber reinforced polymer (FRP) bars which are corrosion resistant can be provided as reinforcement. This research was divided into two phases directed towards the implementation of a nonmetallic reinforced …
Transverse-Earthquake Induced Deformations Of A Bridge Approach Embankment In The New Madrid Seismic Zone, Wanxing Liu, Richard Wesley Stephenson, Ronaldo Luna
Transverse-Earthquake Induced Deformations Of A Bridge Approach Embankment In The New Madrid Seismic Zone, Wanxing Liu, Richard Wesley Stephenson, Ronaldo Luna

It is predicted that strong earthquakes, larger than M 7.0, may occur within next 50 years in the New Madrid Seismic Zone (NMSZ), the location of three of the most powerful earthquakes in United States history. Large displacements may occur during strong earthquakes that can cause an embankment to fail or lose its function. The hyperbolic stress-strain model with Masing rules was modified to account for strength and stiffness reduction due to change in the effective confining pressure. The Byrne model was combined with a hyperbolic model to calculate the pore water pressure caused by seismic shaking. This modified hyperbolic …
