Six full scale column specimens designed for pure flexure failure were tested under severe cyclic displacement histories. Typical column designs were employed in the tests representing code conforming columns. The main variable in the experiments was the imposed displacement histories. The deformation-based performance limits proposed by Eurocode 8 predicted the experimental performance of code-conforming columns quite well, whereas ASCE/SEI 41 performance limits appeared to be highly conservative in predicting the experimental performance of column plastic hinges designed to fail in pure flexure under moderate axial load levels. Analytical studies on SDOF structures representing flexural column behavior revealed that the effect of displacement history on the target drift demands of concrete structures is significant under severe earthquake ground motions.

The Role of precious metal nanoparticles on the oxygen exchange kinetics from ceria Kaya, Deniz; Üner, Deniz; Kıncal, Serkan; Department of Chemical Engineering (2016) The oxygen exchange kinetics of precious metal added ceria and ceria-alumina oxides were investigated by temperature programmed analyses and microcalorimetric measurements. 1 wt. % Pd/CeO2 and 1 wt. % Pd/Al2O3 oxides were synthesized by the incipient wetness method. 1 wt. % Pd/CeO2-Al2O3 oxides with 20 wt. %, 15 wt. % and 10 wt. % loadings of ceria were synthesized by the sequential impregnation method. Temperature programmed reduction (TPR) analysis was performed to analyze the reducibility of prepared oxi...
Evaluation of the Performance Limit States of Reinforced Concrete Columns in View of Experimental Observations Acun, Bora; Sucuoğlu, Haluk (2011-07-01) 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 co...
THE INFLUENCE OF MANUFACTURING DEFECTS ON STRUCTURAL PERFORMANCE OF COMPOSITE OVERWRAPPED PRESSURE VESSELS Yurdakul, Kıvanç; Gürbüz, Rıza; Department of Metallurgical and Materials Engineering (2022-2-04) In this study, the influence of defects that are occurred in manufacturing operations of filament wound composite overwrapped pressure vessels on burst pressure is investigated experimentally. Firstly, material characterization methods such as tensile testing and fiber volume fraction testing of carbon/epoxy composite specimens are completed. Following determining of different layer configurations for small scale composite pressure vessels, manufacturing and burst testing of vessels are accomplished. Ef...
The effect of double austenitization on the microstructure and toughness of AISI M2 high speed steel Ögel, Bilgehan (1998-06-01) In this study, the effect of double austenitization on microstructure and toughness of AISI M2 high speed steel was investigated. For double austenitization treatment, the specimens, which are hardened initially at 1220 degrees C and quenched in air, were hardened for a second time in the temperature range 1150 - 1050 degrees C. For comparison purposes, another set of specimens is austenitized singly in the temperature range 1150 - 1050 degrees C. Tempering process was carried out between 500 - 640 degrees ...
The Influence of different mixture design variables on thermal fatigue cracking of asphalt concrete pavements / Arabzadeh, Ali; Güler, Murat; Department of Civil Engineering (2014) In this study, in order to investigate the thermal fatigue resistance of naturally-aged asphalt concrete specimens, an experimental setup is developed. Mixture design variables, selected according the superpave method of design, include asphalt content, asphalt type, aggregate type, gradation and modification. In the course of this study, using the developed setup, thermal coefficients and thermal fatigue life of the asphalt concrete specimens are measured. Then, using the analysis of variance tests the sig...
