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 conducted using a set of ground motions. In the analyses, the ground motions are scaled to peak ground accelerations ranging between 0.2 and 0.8 g to assess the seismic performance of integral bridges in relation to that of conventional bridges at various ground motion intensities and associated performance levels. The analyses results revealed that integral bridges have superior seismic performance compared to conventional bridges in terms of smaller inelastic rotations at piers and piles, deck displacements, pile axial forces, abutment rotations, pier column drifts and bearing displacements for the bridges under consideration.

Comparative assessment of the efficiency of seismic isolation for seismic retrofitting of highway bridges in regions of low-to-moderate seismicity Karalar, Memduh; Dicleli, Murat (null; 2019-07-06) 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) ana...
Effect of dynamic soil-bridge interaction modeling assumptions on the calculated seismic response of integral bridges Erhan, Semih; Dicleli, Murat (2014-11-01) In this study, the effect of soil-structure modeling assumptions and simplifications on the seismic analyses results of integral bridges (lBs) is investigated. For this purpose, five structural models of lBs are built in decreasing levels of complexity starting from a nonlinear structural model including close numerical simulation of the behavior of the foundation and backfill soil and gradually simplifying the model to a level where the effect of backfill and foundation soil is totally excluded. Nonlinear ...
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...
Effects of Soil Bridge Interaction and Abutment Deck Continuity on the Live Load Distribution Factors in Integral Bridge Components Erhan, Semih; Dicleli, Murat (2009-10-01) In this study, the effects of soil bridge interaction and abutment deck continuity on the live load distribution in integral bridge components are studied. For this purpose, 2-D and 3-D structural models of typical integral and conventional bridges having various structural, geometric and geotechnical properties are built. The analyses of the models are then conducted under AASHTO live load. The analyses results revealed that soil-bridge interaction has significant effects on the live load distribution in a...
Quantitative approach to rapid seismic evaluation of slab-on-girder steel highway bridges Dicleli, Murat (1996-01-01) A quantitative approach follows for developing a methodology for the rapid seismic evaluation and ranking of slab-on-girder steel highway bridges. In the development of this methodology, analytical expressions are introduced to calculate the seismically induced forces and displacements in bridge components, first assuming that damage to bearings is not acceptable and then removing this constraint. In the latter case, the superstructure is assumed to become unrestrained and slide on its supports. The seismic...
