In this study, twelve full-scale column specimens designed for pure flexure were tested under repetitive displacement cycles with high amplitude. Two typical column designs were employed in the production of samples representing sub-standard and code-conforming columns, respectively. The main variable in the experiments was the histories of the imposed displacement amplitudes. The deformation-based performance limits proposed by Eurocode 8, ASCE/SEI 41 and Turkish Seismic Code (TDY-2007) for sub-standard columns were found conservative in view of the test results, which may lead to misleading results in seismic risk assessment of existing concrete structures. On the other hand, according to the test results of code-conforming columns, the performance limits predicted by Eurocode and TDY 2007 are found to be reasonable. However, ASCE/SEI 41 performance limits appear to be somewhat conservative especially in predicting the experimental performance of column plastic hinges under moderate axial load levels.

Performance of Reinforced Concrete Columns Designed for Flexure under Severe Displacement Cycles Acun, Bora; Sucuoğlu, Haluk (2010-05-01) Twelve full-scale column specimens designed for pure flexure failure were tested in this study. Two typical column designs were employed in the tests representing substandard and code-confonning columns, respectively The main variable in the experiments was the imposed displacement history. The deformation-based performance limits proposed for substandard columns by Eurocode 8 and ASCE/SEI 41 were found very conservative in view of the test results, which may lead to misleading results in the seismic risk a...
Experimental Investigation on the Low Cycle Fatigue Life of Piles Karalar, Memduh; Dicleli, Murat (2018-07-13) In this study, the low cycle fatigue tests are conducted to investigate the fatigue life of steel H-piles subjected to thermal induced cyclic strains/displacements. Review of literature revealed that there are few experimental research data on the low cycle fatigue performance of integral bridge steel H-piles. For this purpose, experimental studies on full scale steel H-pile specimens are conducted to simulate cyclic behavior of steel H-piles under thermal effects in integral bridges by considering the effe...

Performance comparisons of seismic assessment methods with PSD test results of a deficient RC frame Ozcebe, G.; KURT, ELİF; Binici, Barış; Kurç, Özgür; Canbay, Erdem; Akpinar, U. (2009-12-01) The accuracy of estimating the performance levels of a deficient RC frame using linear elastic and nonlinear dynamic analysis is evaluated in this study. This was achieved by comparing the response of a structure tested with pseudo-dynamic testing and estimated by the linear elastic assessment procedures along with nonlinear dynamic analysis. The test structure (three bay-two storey planar frame) is a 1/2 scale reinforced concrete frame having masonry infill walls in the central span. The test frame contain...
Evaluation of environmental parameters in logistic regression models for landslide susceptibility mapping Süzen, Mehmet Lütfi (Informa UK Limited, 2012-01-01) The aim of this study was to determine how well the landslide susceptibility parameters, obtained by data-dependent statistical models, matched with the parameters used in the literature. In order to achieve this goal, 20 different environmental parameters were mapped in a well-studied landslide-prone area, the Asarsuyu catchment in northwest Turkey. A total of 4400 seed cells were generated from 47 different landslides and merged with different attributes of 20 different environmental causative variables i...
