Bayesian Survival Analysis for US Concrete Highway Bridge Decks
Publisher: ASCE
Abstract: A leading factor in structural decline of highway bridges is the deterioration of concrete decks. Thus, a method to predict bridge deck performance is vital for transportation agencies to allocate future repair and ...
Using Tensor Factorization to Predict Network-Level Performance of Bridges
Publisher: American Society of Civil Engineers
Retracted: Characterization of Flexural and Shear Cracks in Reinforced Concrete Beams Using Moment Tensor Inversion from Acoustic Emission Signals
Publisher: American Society of Civil Engineers
Abstract: Quantitative characterization of fracture mechanisms in concrete is a challenging problem that has not been convincingly solved to date. Several monitoring approaches have been proposed to capture and characterize different ...
Data Mining of Bridge Concrete Deck Parameters in the National Bridge Inventory by Two-Step Cluster Analysis
Publisher: American Society of Civil Engineers
Survival Analysis of Concrete Highway Bridge Decks in Oregon Utilizing LASSO and Stepwise-Variable Selection
Publisher: ASCE
Abstract: This research studied the relationship between Oregon national bridge inventory (NBI) data as well as additional design/detailing variables and concrete highway bridge deck performance. Cox proportional hazards regression ...
Heterogeneity-Based Survival Analysis of NBI Condition Ratings for Concrete Highway Bridge Decks in Oregon by Condition Group
Publisher: ASCE
Abstract: This study applied a heterogeneity-based survival analysis to determine significant contributing factors to a bridge deck’s time-in-condition rating (TICR) by condition rating (CR) group: high CR, medium CR, and low CR. ...
Estimating Prestressed Concrete Bridge Reliability and Rating Factors Using Bayesian Networks with an Application to a Bridge Made Continuous for Live Load
Publisher: American Society of Civil Engineers
Abstract: The bridge inspection process has multiple steps. One obvious element is for inspectors to identify defects in the main components of the structural system and assign condition ratings. These condition ratings are somewhat ...
Detection of Vehicles with Studded Tires Using Acoustic Emission Sensors Mounted to Highway Bridges
Publisher: American Society of Civil Engineers
Abstract: Transportation agencies expend large amounts of money annually to maintain highway wearing surfaces. Wear depends mainly on axle weight, vehicle speed, temperature, surface type, and the type of tires mounted on vehicles. ...
Experimental Setup for a Large-Scale Bridge Superstructure Model Subjected to Waves
Publisher: American Society of Civil Engineers
Abstract: To gain a better understanding of the wave forces that led to the failure of numerous causeway-type coastal highway bridges along the U.S. Gulf coast, a series of experiments was conducted on a realistic, 1:5 scale reinforced ...
Performance of US Concrete Highway Bridge Decks Characterized by Random Parameters Binary Logistic Regression
Publisher: ASCE
Abstract: This study employs a random parameters binary logistic regression (LR) to characterize the impact of environmental and structural parameters on concrete highway bridge deck deterioration nationwide. Two specific gaps in ...
