Mechanical behavior of CFRP confined low strength concretes subjected to simultaneous heating-cooling cycles and sustained loading

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 experimental test results show that heating-cooling cycles alone have insignificant effect on the mechanical properties of CFRP-wrapped specimens. However, as for simultaneous exposure of sustained loading and heating-cooling cycles the main difference is on the shape of the stress-strain diagram, in which the bilinear response becomes clear. The other difference is on the ultimate strain, which decreases up to 29 and 15% for cylindrical and prismatic specimens, respectively.

Closure to "Punching shear strengthening of reinforced concrete flat plates using carbon fiber reinforced polymers" by Baris Binici and Oguzhan Bayrak
Binici, Barış (American Society of Civil Engineers (ASCE), 2006-03-01)
This research presents a strengthening technique for increasing punching shear resistance in reinforced concrete flat plates using carbon fiber reinforced polymers (CFRPs). This strengthening method employs CFRP strips in the vertical direction as shear reinforcement around the concentrated load area in a specified pattern. Experimental load deflection curves, strain measurements, and failure modes are reported for four strengthened specimens and two reference specimens tested for the research reported here...
Physical theory hysteretic model for steel braces
Dicleli, Murat (American Society of Civil Engineers (ASCE), 2008-07-01)
This paper presents a simple yet efficient physical theory model that can be used to simulate the inelastic cyclic axial force-axial deformation and axial force-transverse deformation relationships of steel braces. The model consists of a brace idealized as a pin ended member with a plastic hinge located at its midlength. Input parameters of the model are based only on the properties of the brace. The model combines analytical formulations based on the nonlinear behavior of the brace with some semiempirical...
Parameter optimization on compressive strength of steel fiber reinforced high strength concrete
Ayan, E.; Saatcioglu, Oe.; Turanlı, Lutfullah (Elsevier BV, 2011-06-01)
This paper illustrates parameter optimization of compressive strength of steel fiber reinforced high strength concrete (SFRHSC) by statistical design and analysis of experiments. Among several factors affecting the compressive strength, five parameters that maximize all of the responses have been chosen as the most important ones as age of testing, binder type, binder amount, curing type and steel fiber volume fraction. Taguchi analysis techniques have been used to evaluate L-27 (3(13)) Taguchi's orthogonal...
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 ...
Evolutionary structural optimization of steel gusset plates
Khalaf, A. A.; Saka, M. P. (Elsevier BV, 2007-01-01)
Evolutionary structural optimization is applied to determine the optimum shape of steel gusset plates subjected to axial forces. A number of different gusset plates used in various types of connections is considered for this purpose. The evolutionary structural optimization approach is employed to find the optimum shapes of a gusset plate used in these connections. The first example considers a gusset plate having two holes which are utilized in the connection of double angle carrying a tensile force. Withi...
