In this study, the effect of the high frequency components of near fault ground motions (NFGM) with forward rupture directivity effect (FRDE) on the seismic response of elastic and inelastic SDOF regular (non-isolated) and seismic isolated structures is studied. For this purpose, Moving Average filtering method is used to remove the high frequency content of the NFGM at various filtering levels. The key motive for this effort is to evaluate the appropriateness of representing the NFGMs by decomposed signals or mathematical pulse waveforms. Then, elastic and inelastic SDOF structures with various properties are subjected to the original and filtered NFGM and the responses are compared via elastic and inelastic response spectra. In addition, the efficiency of several pulse models in simulating the actual effect of NFGM on the seismic response of elastic and inelastic SDOF structures is investigated. The analyses results revealed that the high frequency content of NFGM has a significant effect on short period elastic structures and inelastic structures with high yield strength subjected to NFGM with short pulse periods. Furthermore, it is found that popular pulse models available in the literature failed to simulate the effect of the actual NFGM on the response of elastic and inelastic structures.

Effect of modifying bearing fixities on the seismic response of short- to medium-length bridges with heavy substructures
Hindi, R; Dicleli, Murat (SAGE Publications, 2006-02-01)
The effect of modifying the fixity conditions of the bearings on the seismic response and vulnerability of existing bridges with heavy substructures is studied. For this purpose, nonlinear seismic analysis of a typical bridge with heavy substructures is conducted to assess its seismic response and vulnerabilities. Next, the bearings are modified to obtain four different configurations of bearing fixities over the substructures. Nonlinear seismic analyses of the bridge are conducted to assess its seismic res...

Dicleli, Murat (Elsevier BV, 2010-01-01)
In this study, the effect of soil-bridge interaction on the magnitude of the internal forces in integral abutment bridge (IAB) components due to live load effects is studied. For this purpose, structural models of typical IABs are built by including and excluding the effect of backfill and foundation soil. Analyses of the models are then conducted under an AASHTO live load. In the analyses, the effects of the backfill and foundation soil on the magnitude of the internal forces in IAB components are studied ...
Effect of shear walls on the behavior of reinforced concrete buildings under earthquake loading
Çömlekoğlu, Hakkı Gürhan; Burak Bakır, Burcu; Department of Civil Engineering (2009)
An analytical study was performed to evaluate the effect of shear wall ratio on the dynamic behavior of mid-rise reinforced concrete structures. The primary aim of this study is to examine the influence of shear wall area to floor area ratio on the dynamic performance of a building. Besides, the effect of shear wall configuration and area of existing columns on the seismic performance of the buildings were also investigated. For this purpose, twenty four mid-rise building models that have five and eight sto...

Burak Bakır, Burcu (American Society of Civil Engineers (ASCE), 2013-11-01)
An analytical study is performed to evaluate the effect of shear wall area to floor area ratio on the seismic behavior of midrise RC structures. For this purpose, 24 midrise building models that have five and eight stories and shear wall ratios ranging between 0.51 and 2.17% in both directions are generated. Then, the behavior of these building models under earthquake loading is examined by carrying out nonlinear time history analyses. In the analyses, seven different ground motion records are applied to th...

Dicleli, Murat (Informa UK Limited, 2011-05-01)
In this study, the effect of foundation soil stiffness on the seismic performance of integral bridges (IBs) is investigated. For this purpose, nonlinear structural models of a two-span TB with four different foundation soil stiffness types (loose, medium, medium-dense and dense sands) are built. In the nonlinear structural models, nonlinear soil structure interaction including free-field effects is considered. Then, the nonlinear time history analyses of the TB models are conducted using a set of ground mot...
