The behaviour of carbon fibre reinforced polymer-confined cylindrical and prismatic concrete specimens subjected to several different environmental conditions was investigated in four groups. The first group of specimens was used as a reference. In the second group, specimens were exposed to dry heating-cooling (H-C) cycles in the environmental test chamber (ETC), whereas specimens in the third group were kept in water while simultaneously being subjected to H-C cycles in the ETC. Finally, the last group of specimens was kept outside of the laboratory to determine the outdoor environmental effect. After the ageing phase, specimens were tested under monotonic uniaxial loading to determine the change in their mechanical properties. Cylindrical specimens were observed not to be significantly affected by H-C cycles with the exception of their ultimate strain, which decreased under outdoor conditions. As for the prismatic specimens, dry H-C cycles were found to reduce strength by up to 24% and strain by up to 33%. Wet H-C cycles and outdoor exposure were seen to decrease further the strength and ultimate strain of prismatic specimens.

Tensile behavior of post-installed chemical anchors embedded to low strength concrete YILMAZ, SALİH; Özen, Muhammet Ali; YARDIM, YAVUZ (Elsevier BV, 2013-10-01) In the scope of this paper, tensile capacities of post-installed chemical anchors embedded to 5.9 and 10.9 MPa concrete blocks are investigated. Pull-out tests are applied to 80 ductile steel bars (S420a). For the anchor diameters, 12, 16 and 20 mm are chosen. On the other hand, 10, 15 and 20 times the bar diameter are selected as free-edge distance and embedment depth for monotonic tensile loading tests. The results indicate that installation of anchors into low-strength concrete with sufficient embedment ...
Active and non-active porosity in concrete. Part I: Experimental evidence Yaman, İsmail Özgür; Aktan, H.M. (Springer Science and Business Media LLC, 2002-03-01) The findings of an experimental study are described, documenting and quantifying the influence of concrete porosity on its mechanical properties in saturated and dry states. Concrete porosity consists of capillary and entrained air, and described respectively as active and non-active, depending on its influence on mechanical properties with changing moisture state. It was found that the active (capillary) porosity influence on mechanical properties is more pronounced with decreasing moisture. The influence ...
Mechanical behavior of CFRP confined low strength concretes subjected to simultaneous heating-cooling cycles and sustained loading Erdil, B.; Akyüz, Uğurhan; Yaman, İsmail Özgür (Springer Science and Business Media LLC, 2012-01-01) This study aims to present the mechanical behavior of carbon fiber reinforced polymers (CFRP) reinforced low strength cylindrical and prism concrete specimens under both heating-cooling cycles and sustained loading. Heating-cooling cycles range from -10 to 50A degrees C and the applied sustained load level is 40% of the ultimate strength of concrete. After 200 heating-cooling cycles and/or sustained load testing, specimens were tested to determine the mechanical behavior under uniaxial compression. The expe...
Performance Examination of Two Seismic Strengthening Procedures by Pseudodynamic Testing Kurt, Efe Gokce; Kurç, Özgür; Binici, Barış; Canbay, Erdem; Ozcebe, Guney (American Society of Civil Engineers (ASCE), 2012-01-01) Pseudodynamic testing was employed to observe the seismic performance of two retrofit methods on two-story, three-bay frame structures. The test frames had hollow clay tile (HCT) infill in the central bay and incorporated the seismic deficiencies of Turkish construction practice, such as use of plain reinforcing bars, low-strength concrete, and insufficient confining steel. Two noninvasive and occupant-friendly retrofit schemes suggested in the Turkish Earthquake Code, namely, use of fiber-reinforced polyme...
Hybrid fiber reinforced self-compacting concrete with a high-volume coarse fly ash Sahmaran, Mustafa; Yaman, İsmail Özgür (Elsevier BV, 2007-01-01) This paper presents a study on the fresh and mechanical properties of a fiber reinforced self-compacting concrete incorporating high-volume fly ash that does not meet the fineness requirements of ASTM C 618. A polycarboxylic-based superplasticizer was used in combination with a viscosity modifying admixture. In mixtures containing fly ash, 50% of cement by weight was replaced with fly ash. Two different types of steel fibers were used in combination, keeping the total fiber content constant at 60 kg/m(3). S...
