Accumulation of research in the field of bridge evaluation based on structural reliability justifies the consideration of reliability index as the primary measure of safety for bridges. Furthermore, the lifetime bridge evaluation techniques are being mostly based on reliability methods. Currently, bridge safety is measured in terms of the rating factor, which reflects the live load capacity of the structure. In order to investigate the reliability index of an existing bridge and to consider its relation to the rating factor, an in-depth investigation of the interaction between these two safety measures for different limit states of different bridge types is desirable. This paper presents the results of a study in which the interaction between rating and reliability of a group of 14 bridges in an existing bridge network was investigated. This investigation is based on advanced methods to evaluate the reliability of each bridge in the network. Rating factors for different bridge groups are identified based on bridge type, and bridge groups are compared based on mean group rating factor. Bridge rating and reliability are quantified when each bridge starts its service life. The bridge rating factor and the reliability index are evaluated for various limit states belonging to different member types within the bridge network. A correlation study between bridge rating factor and reliability index of different bridge types in an existing network reveals interesting results.

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...
Development of Fragility Curves for Single-Column RC Italian Bridges Using Nonlinear Static Analysis Perdomo, Camilo; Monteiro, Ricardo; Sucuoğlu, Haluk (Informa UK Limited, 2020-05-07) The main objective of this study is to assess the accuracy and suitability of Nonlinear Static Procedures (NSPs) in the development of analytical damage fragility curves for seismic risk assessment of large portfolios of Reinforced Concrete (RC) bridges. Seven NSP approaches, from widely used single-mode conventional pushover-based approaches to the more rigorous multi-mode conventional or adaptive pushover-based procedures are implemented. By systematically comparing fragility curve estimations in terms of...
Frame Element for Metallic Shear-Yielding Members under Cyclic Loading Sarıtaş, Afşin (American Society of Civil Engineers (ASCE), 2009-09-01) Modeling the energy dissipation capacity of shear-yielding members is important in the evaluation of the seismic response of earthquake resistant structural systems. This paper presents the model of a frame element for the hysteretic behavior of these members. The model is based on a three-field variational formulation with independent displacement, stress, and strain fields. The displacement field is based on the Timoshenko beam theory. The nonlinear response of the element is derived from the section inte...
Efficient energy dissipating steel-braced frame to resist seismic loads Dicleli, Murat (American Society of Civil Engineers (ASCE), 2007-07-01) In this research, the seismic performance of a proposed efficient energy dissipating steel-braced frame (EEDBF) in relation to that of a moment-resisting frame (MRF) and chevron braced frame (CBF) is studied. The frame is intended to combine the advantages of MRF and CBF and eliminate most of the disadvantages pertinent to these frames. Nonlinear static pushover, time history, and damage analyses of the three frames are conducted to assess the performance of the EEDBF compared to that of MRF and CBE The ana...
