Abstract
This paper proposes a performance-based resistance deterioration model that reflects the site environment and inspection data for highway bridges. Traffic characteristics and corrosive environment are considered as the site environment. The corrosive environments and traffic characteristics are classified into three categories, namely mild, normal, and severe for the former and light, normal, and heavy for the latter. The deterioration of the resistance capacity due to corrosive environments is evaluated considering both the service period and the concrete crack widths in the pre-stressed concrete (PSC) girder and the reinforced concrete (RC) slab. The deterioration model of the resistance capacity is calibrated by combining the performance degradation model. The performance degradation model is also calibrated using previous bridge inspection results from the standard performance degradation model, which has been developed based on the large amount of data available on many pre-stressed concrete-I (PSC-I) type girder bridges. The developed performance-based resistance deterioration model is used to evaluate the reliability of a bridge in the future. The results show that the performance inspection outcomes, either based on the current status or lifetime inspection history, are critical in estimating the future degradation of the reliability level, inherent to the bridge.

The basic resistance capacity of the pre-stressed stressed concrete-I (PSC-I) girder bridge was evaluated by using the flexural strength equation from concrete-I (PSC-I) girder bridge was evaluated by using the flexural strength equation from the the load-and-resistance factor design (LRFD) bridge design specifications [9]
Summary
Bridges play a significant role in national economic development and public welfare. Damage to major bridges results in direct losses such as loss of life and damage to structures, and indirect losses such as loss to the local economy. Gua et al [6] evaluated the total life-cycle benefits of using high performance concrete with internal curing bridge decks compared to normal concrete bridge decks in a transportation network. These studies have limited scope for analyzing the performance degradation by reflecting traffic characteristics, the corrosive environment, and inspection data of the actual bridge. This study deals with the safety and reliability analysis of the performance of structures, and performance-based resistance deterioration model is presented to evaluate the reliability of bridge a performance-based resistance deterioration model is presented to evaluate the reliability of bridge reflecting the site’s environment, such as traffic characteristics and corrosive environments.
