This article presents an analytical study carried out to investigate seismic response of a lightly reinforced stiff shear wall structure subjected to ground motions classified as near- or far-field. A five-story lightly reinforced shear wall model structure that has been studied both experimentally and analytically in the context of a coordinated research project has been employed. Several response parameters were obtained by linear and nonlinear analyses under a suite of 55 ground motion records on firm soils. Additional analyses are performed to investigate the validity and range of applicability of the most widely used approximate displacement based analysis procedures. The approximate procedures considered are found to be deficient in representing the actual response of the structure employed here regardless of the type of excitation.

Evaluation and selection of ground motion intensity measures for nonlinear seismic demand and fragility analysis of MDOF systems
Kadaş, Koray; Yakut, Ahmet; Department of Civil Engineering (2021-5-21)
In performance-based seismic design methodology, intensity measures are thought to be key parameters of ground motion records that relate the seismic hazard levels with the structural response or damage. Therefore, it is important to identify efficient intensity measures that are capable of reducing the variability in seismic demand predictions. There exist several simple-to-advanced scalar and vector ground motion intensity measures; however, the literature is limited in the number of comparative studies i...
Evaluation of shear wall indexes for reinforced concrete buildings
Soydaş, Ozan; Yakut, Ahmet; Department of Civil Engineering (2009)
An analytical study was carried out to evaluate shear wall indexes for low to mid-rise reinforced concrete structures. The aim of this study was to evaluate the effect of different shear wall ratios on performance of buildings to be utilized in the preliminary assessment and design stages of reinforced concrete buildings with shear walls. In order to achieve this aim, forty five 3D building models with two, five and eight storeys having different wall ratios were generated. Linearly elastic and nonlinear st...
Seismic response assessment of a stiff structure
Kazaz, I; Yakut, Ahmet; Gulkan, P (Wiley, 2006-05-01)
Seismic response of a lightly reinforced stiff shear-wall structure subjected to ground motions grouped as near- or far-field according to their distance to causative faults is investigated. A model structure that had earlier been studied both experimentally and analytically in the context of a co-ordinated research project is re-examined. The structure is a five-storey lightly reinforced shear-wall model subjected analytically to 55 ground motion records from firm soil sites. Several response parameters ar...
Comparison of Real and Simulated Records Through Selected Seismic Intensity Measures
Karim Zadeh Naghshineh, Shaghayegh; Askan Gündoğan, Ayşegül; Yakut, Ahmet (null; 2017-12-11)
Recent studies have shown that simulated ground motions could be utilized to determine the seismic vulnerability of structures where there are limited number of real ground motion records compatible with seismological characteristics of the area of interest. Among various simulation techniques, stochastic finite-fault methodology is believed to practically simulate realistic broadband records including the frequencies which affect the built environment. This study aims to compare the main characteristics of...
Radial motion of highly conducting sphere in magnetic field
Gurcan, OD; Mirnov, VV; Ucer, D (2000-05-01)
Radial motion of a highly conducting sphere in external magnetic field is considered. It both perturbs the external magnetic field and generates an electric field. Exact analytic solution has been obtained previously for a uniformly expanding sphere. In the present paper a new exact solution is derived which is valid not only for expansion but for contraction as well. It allows us to calculate analytically the total electromagnetic energy irradiated by the sphere involved in periodical radial motion with ar...
