must establish deterioration rates for each bridge element. Accurate deterioration rate models for elements such as bridge decks, joints and steel coating exist due to their recurrent replacement and repair. However, no statistical or data driven prediction model currently exists for deterioration of concrete bridge substructures. Research. "The book follows a basic logic line from concrete materials to structural design, and the content is accordingly divided into three parts Overall, the book provides good coverage of the topic and valuable information for the understanding of deterioration processes of concrete structures.

Several authors have developed deterioration models for concrete bridge elements, which are discussed in the following sub-sections. However, there are only limited studies available on the deterioration prediction of timber bridge by: 1.
The third example illustrates the ANN-based deterioration model for reinforced concrete bridge decks in Florida based on the NBI condition data for the years – The training set accuracy and testing set accuracy in the ANN model are found to be 91% and 88% by: 1.
Discussion and Closure: Condition Prediction of Deteriorating Concrete Bridges Using Bayesian Updating Journal of Structural Engineering Vol.Issue 10 (October )Cited by: Experience has demonstrated that highway bridges are vulnerable to damage from environmental attack, such as alkali-silica reaction, corrosion, and freeze-thaw.
To make rational decisions in a life-cycle cost perspective, reliable prediction of the service life of deteriorating highway bridges is by: Deterioration models for prediction of remaining useful life of timber and concrete bridges: A review Article (PDF Available) March with 64 Reads How we measure 'reads'.

The main problem of estimating the future maintenance of bridge stocks is the hetero-geneous composition of bridge stocks. A few examples of the heterogeneity are. (a) assessment of bridge conditions, (b) forecasting of further bridge deterioration, and (c) identification and prioritization of maintenance needs and their corresponding financial requirements.
There are a large number of bridges in Australia that are in conditions of serious deterioration (Stewart, ). Gamma prediction models for long-term creep deformations of prestressed concrete bridges.
Journal of Civil Engineering and Management: Vol. 23, No. 6, pp. America and elsewhere. Several technologies are available for assessing the condition of concrete bridges and a number of deterioration models are used to predict future bridge conditions and estimate associated funding requirements.
This paper critically reviews the different available condition assessment and deterioration prediction Author: Tarek Omar, Moncef L. Nehdi. For diagnosis, concrete bridges are divided into 2 classes depending on their in-service period: over or within 30 years after completion.
This criterion was established based on existing research findings that indicate the deterioration of concrete bridges progresses rapidly within 30 years if exposed to severe chloride attack.

Chloride-induced corrosion is widely accepted as one of the primary causes of premature deterioration for concrete structures in marine or deicing salt environment. For precast concrete (PC) structures, such durability problems may even be severer because defects in joint areas, e.g., cracks caused by grout shrinkage and improper construction, can accelerate chloride ion.
