Due to the dwindling maintenance budget and lack of qualified bridge inspectors, bridge-management agencies in Taiwan need develop cost-effective inspection strategies preserve safety functionality their aging, natural disaster-prone bridges. To inform development such a strategy, this study examined big data stored Bridge Management System (TBMS) using knowledge discovery databases (KDD) proce...

The effects of corrosion focusing on the consequences bond strength deterioration for a reinforced concrete bridge pier in seismic affected area are examined this research. A degradation model based local stress-slip presented FIB Model Code 2010 is chosen. motorway overpass object previous study, which considered rebars cross-section reduction effect only, has been selected to assess capacity ...

Bridge deck deterioration modeling is critical to infrastructure management. Deterioration traditionally done using deterministic models, stochastic and recently basic machine learning methods. The advanced learning-based survival such as random forest, have not been adapted for use in This paper introduces forest models bridge compare their performance with a commonly used traditional model, t...

Ground-Penetrating Radar (GPR) is a popular non-destructive technique for evaluating RC bridge elements as it can identify major subsurface defects within short span of time. The data interpretation the GPR profiles based on existing amplitude-based approaches not completely reliable when compared to actual condition concrete with destructive measures. An alternative image-based analysis consid...

With the increased demand placed on aging infrastructure, there is great interest in new condition assessment tools for bridges. The routine deterioration that bridges undergo causes a loss in the intended performance that, if undetected or unattended, can eventually lead to structural failure. Currently the primary method of bridge condition assessment involves a qualitative bridge inspection ...

The threat to safety of aging bridges has been recognized as a critical concern to the general public due to the poor condition of many bridges in the U.S. Currently, the bridge inspection is conducted manually, and it is not efficient to identify bridge condition deterioration in order to facilitate implementation of appropriate maintenance or rehabilitation procedures. In this paper, we repor...
