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 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 (MMRS) analysis of the bridge was then conducted to account for the non-linear behavior of the bridge components and soil-bridge interaction. The calculated seismic demands were compared with the estimated capacities of the bridge components to determine those that need to be retrofitted. It was found that the bearings, wingwalls and pier foundations of the considered typical bridge need to be retrofitted.

The calculated seismic demands were compared with the estimated capacities of the bridge components to determine those that need to be retrofitted. It was found that the bearings, wingwalls and pier foundations of the considered typical bridge need to be retrofitted. A conventional retrofitting strategy was developed for the bridge and the cost of retrofit was estimated. Next, the bridge was further studied to develop appropriate techniques for upgrading its seismic capacity using FPB to eliminate the need for seismic retrofitting of its vulnerable substructure components. It was observed that the use of FPB mitigated the seismic forces and eliminated the need for retrofitting of the substructure components of the bridge. An average retrofitting cost using FPB was calculated and found to be less than the cost of conventional retrofitting considered in this study. Thus, FPB may successfully be used for economical seismic retrofitting of typical bridges in the State of Illinois or in regions of low to moderate risk of seismic activity

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 ...
Seismic Retrofitting of Typical Illinois Bridges by Response Modification
Dicleli, Murat (null; 2004-01-01)
The impact of seismic retrofitting of typical Illinois bridges, via response modification using friction pendulum bearings (FPB), on the state economy is studied. For this purpose, two typical bridges with distinct characteristics were selected by Illinois Department of Transportation (IDOT). The seismic analyses of the bridges revealed that the bearings, wingwalls and substructures are vulnerable and need to be retrofitted. Conventional retrofitting strategies are developed for the bridges and the retrofit...
Comparative assessment of the seismic performance of integral and conventional bridges with respect to the differences at the abutments
Erhan, Semih; Dicleli, Murat (2015-02-01)
In this study, the seismic performance of integral and conventional bridges is compared particularly considering the differences at their abutments. For this purpose, three existing integral bridges with one, two and three spans are selected and then designed as conventional jointed bridges. The structural models of the integral and conventional bridges are then built including nonlinear structural and dynamic soil-bridge interaction effects. Next, nonlinear time history analyses of the bridge models are co...
Equivalent linear analysis of seismic-isolated bridges subjected to near-fault ground motions with forward rupture directivity effect
Dicleli, Murat (2007-01-01)
This study encompasses the assessment of the equivalent linear (EL) analysis procedure for the design of seismic isolated bridges (SIB) subjected to near-fault ground motions with forward rupture directivity effect. The assessment procedure involves the comparison of the seismic response quantities obtained from EL analyses with those obtained from nonlinear time history (NLTH) analyses. The effect of several isolator and near-fault ground motion properties are considered in the assessment of the EL analysi...
Comparison of the Overlapping Lattice and the Finite Element Approaches for the Prediction of the Collapse State of Concrete Gravity Dams
Soysal Albostan, Berat Feyza; Arıcı, Yalın; Binici, Barış; Tuncay, Kağan (2017-10-13)
Estimating the collapse limit state of concrete gravity dams within the framework of performance based design is challenging due to the uncertainty in modelling the response of these systems and the strong dependence of the behavior on the ground motion. In this context, the purpose of the study is to investigate the prediction capability of numerical tools in determining the collapse state of concrete gravity dams. The first tool used to this end is the classical finite element method with the smeared crac...
