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 effect of axial load combined with large amplitude strain cycles with various amplitude levels. Using experimental test results, the effect of axial load level is investigated on the low cycle fatigue performance of integral bridge steel H-piles. It is observed that the effect of axial load on the low cycle fatigue performance of integral bridge steel H-piles are so important to reduce the bending stresses in the steel H-piles and also increase the low-cycle fatigue performance of steel H-piles at the abutments of integral bridges at the moderate strain amplitudes. Moreover, it is observed that at large strain amplitudes the effect of local buckling should be considered more than the effect of axial load on the low cycle fatigue life of steel H-piles at the abutments of integral bridges.

Experimental investigation of axial load on low cycle fatigue performance of steel H-piles in integral bridges Dicleli, Murat (null; 2017-08-28) In this study, the effect of axial load on the low cycle fatigue performance of integral bridge steel H–piles is investigated. Review of literature revealed that there is no experimental research data on the effect of axial load 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 Hpiles under thermal effects in integral bridges by considering the effect of axial l...
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 effects of positive core self and external evaluations on performance appraisals Güven, Lale; Sümer, Canan H; Department of Industrial and Organizational Psychology (2007) The purpose of this study was to investigate the effects of core self-evaluations (CSEs) and core external-evaluations (CEEs) on performance evaluations. It was hypothesized that people with higher levels of CSEs and CEEs would be more lenient in their performance ratings, when rating neutral performance. The second hypothesis of the study was that people with higher and lower CSEs would engage more in halo when rating neutral performance compared to people with average levels of CSEs. It was further hypoth...
A Computational analysis on rotor-propeller arm interaction in hovering flight Yener, Serkan.; Perçin, Mustafa; Department of Aerospace Engineering (2019) This study presents a computational analysis on the interaction between rotor and different rotor frame-arm geometries in hovering flight. The influence of the frame arm on the aerodynamic performance of the rotor is assessed by using commercially available computational fluid dynamics (CFD) solver software ANSYS Inc. Fluent 17. Numerical results are validated for hovering and forward vertical climb flight conditions with thrust and torque measurements conducted on a 16x4 carbon fiber propeller. The thrust ...
