Book Description
Corrosion is one of the main causes of deterioration of bridges. Structures exposed to harsh environmental conditions are subjected to time-variant changes of their load-carrying capacity. Thus, there is a need for an evaluation to accurately assess the actual condition and predict the remaining life of a structure. System reliability can be used as an efficient tool in evaluation of existing structures. The traditional approach is based on the consideration of individual components rather than the system as a whole. However, it has been observed that the load-carrying capacity of the whole system often is much larger than what is determined by the design of components. Quantification of this difference is the scope of this study.

Book Description
Bridge - girder deterioration model is formed based on diffusivity process, corrosion development, and cracks propagation. The chloride diffusivity is studied based on previous researches0́9 experimental work while corrosion penetration is analyzed based on mathematical model. Corrosion products cause cracks then spalling. Therefore, in the few decades, the utilize of fiber-reinforced polymer (FRP) materials to strengthen highway bridges has obtained in popularity. sensible cost, speed and ease of installation, and limited disruption of the use of the structure have shared to the adoption of FRP systems over other strengthening options. In order to reduce the corrosion with the bridge deterioration. Fiber Reinforced Polymer (FRP) is one of the top solutions to reduce corrosion and strengthen bridge - girders, by placing FRP on the side(s) of the reinforced concrete beam and reduce the influence of chloride diffusivity through reinforced concrete. Thus, the deterioration with reinforced concrete based on corrosion with section warped with FRP is less than with the corrosion of reinforced concrete section unwrapped with FRP. The objective of this study is to develop a reliability - deterioration model based on corrosion in steel, concrete cover spalling, and FRP debonding. The reliability is reduced due to two independent deterioration factors that developed simultaneously with Life Cycle Time (LCT). The corrosion in steel rebar is the first deterioration factor that causes reduction in flexural moment capacity, and spalling. Moreover, the second deterioration factor is the surrounded environment that may causes FRP debonding. Monti Carlo Simulation (MCS) of reliability-based deterioration model is programmed and used in order to compute failure probability by using FORTRAN 90 to analyze the bridge 0́3 girder model including all design parameters.

Book Description
This book addresses probabilistic methods for the evaluation of structural reliability, including the theoretical basis of these methods. Partial safety factor codes under current practice are briefly introduced and discussed. A probabilistic code format for obtaining a formal reliability evaluation system that catches the most essential features of the nature of the uncertainties and their interplay is then gradually developed. The concepts presented are illustrated by numerous examples throughout the text. The modular approach of the book allows the reader to navigate through the different stages of the methods.
