In this first part of a two-part paper, a general methodology for lifetime performance analysis of existing reinforced concrete bridges is presented. The framework for the methodology is established by identifying four distinct categories: limit state equations, random variables, deterministic parameters, and constant coefficients. The limit state equations are derived by strictly adhering to the load and capacity formulas and requirements set forth in AASHTO specifications. Generality is pursued by establishing parametric limit state equations such that the formulas are applicable to any type of reinforced concrete bridge having similar superstructure components. The methods presented in this paper for reinforced concrete bridges are part of a larger study focusing on lifetime performance evaluation of multiple bridge types in an existing bridge network. For time-variant performance analysis, special emphasis is placed on the chloride penetration modeling in slab and girders. In the companion paper, the lifetime performance of reinforced concrete slabs and girders in an existing bridge network is investigated and results are presented for three bridges located in Colorado.

Lifetime Performance Analysis of Existing Reinforced Concrete Bridges. II: Application Akgül, Ferhat (American Society of Civil Engineers (ASCE), 2005-06-01) This study, being the second part of a two-part paper, presents the application of a lifetime performance analysis methodology to three reinforced concrete bridges located in an existing bridge network in Colorado. The focus of this paper is on reinforced concrete slabs and girders of these bridges. The limit state equations were previously derived in the companion paper by grouping the random variables, deterministic parameters, and constant coefficients in such a way that the formulas are applicable to re...
Lifetime performance analysis of existing prestressed concrete bridge superstructures Akgül, Ferhat (American Society of Civil Engineers (ASCE), 2004-12-01) A general methodology for lifetime performance analysis of existing prestressed concrete girder bridges is presented. Only the superstructure components (slab and girders) are considered. The framework for the methodology is established by identifying four distinct categories: limit state equations, random variables, deterministic parameters, and constant coefficients. The limit state equations are derived by strictly adhering to the load and capacity formulas and requirements set forth in AASHTO specificat...
Lifetime performance analysis of existing steel girder bridge superstructures Akgül, Ferhat (American Society of Civil Engineers (ASCE), 2004-12-01) A general method for lifetime performance analysis of existing steel girder bridges is presented. Only the superstructure components are considered. The formulation is established by identifying four distinct categories: limit state equations, random variables, deterministic parameters, and constant coefficients. The limit state equations are derived by strictly adhering to the load and capacity formulas and requirements set forth in AASHTO specifications. Generality is pursued by establishing parametric li...
Upgrading of slab-column connections using fiber reinforced polymers Binici, Barış (Elsevier BV, 2005-01-01) The results of an experimental program on upgrading of reinforced concrete slab-column connections subjected to monotonic shear and unbalanced moment transfer are presented in this study. Externally installed carbon fiber reinforced polymer (CFRP) stirrups acting as shear reinforcement around the slab-column connection area were used with two patterns of CFRP arrangements. It was found that the proposed method resulted in punching shear capacity increases up to 60% relative to the specimen without any stren...
Seismic retrofitting of highway bridges in Illinois using friction pendulum seismic isolation bearings and modeling procedures Dicleli, Murat (Elsevier BV, 2003-07-01) In this paper, the economical and structural efficiency of friction pendulum bearings (FPB) for retrofitting typical seismically vulnerable bridges in the State of Illinois is studied. For this purpose, a bridge was carefully selected by the Illinois Department of Transportation (IDOT) to represent typical seismically vulnerable bridges commonly used in the State of Illinois. A comprehensive structural model of the bridge was first constructed for seismic analysis. An iterative multi-mode response spectrum ...
