Comparison of concrete mixtures containing steel mesh, steel fiber and polypropylene fibers were evaluated in terms of toughness, flexural strength, compressive strength and split tensile strength. Five types of concrete were prepared with steel mesh, steel fiber and polypropylene fiber with the identical water/cement (w/c) ratio and the identical workability. 10x60x60 cm plates, 8x8x32 cm beams and 10x20 cm cylindrical concrete specimens were prepared. Compressive strength, split-tensile strength and toughness of the concrete specimens were determined at 7, 28 days of age and the results were compared. According to the results obtained from the tests, concrete made with steel mesh showed the best performance in panel tests. Also the results of the beam tests were compared with the plate test to determine the effectiveness of using beam test for toughness instead of plate test. The panel test was observed to be better for determining toughness than the beam test.

Comparative evaluation of steel mesh, steel fibre and high-performance polypropylene fibre reinforced shotcrete in panel test
Cengiz, O; Turanlı, Lutfullah (2004-08-01)
In this study, experimental investigations were performed on steel mesh (SM), steel fibre (SF) and high-performance polypropylene fibre (HPPF) reinforced shotcrete (HPPFRS) panels to evaluate performance characteristics such as toughness, flexural ductility, energy absorption and load capacity. The panel tests, in accordance with European specification for sprayed concrete (EFNARC), were made on 18 prismatic specimens having the same mix designs and were cured for 28 days but reinforced with various fibres....
Analytical modeling of fiber reinforced composite deep beams
Yağmur, Eren; Burak Bakır, Burcu; Department of Civil Engineering (2018)
Discrete fibers are often used as reinforcement to increase the tensile and shear strengths of concrete. For many years, the behavior of fiber reinforced composite members has been investigated both experimentally and analytically. The influence of fibers on the behavior of shear critical members is quite significant, therefore, it is inevitable to develop a method, which estimates the shear strength of fiber reinforced composite deep beams realistically. This is why one of the main objectives of this study...
Seismic upgrading of reinforced concrete frames with structural steel elements
Özçelik, Ramazan; Binici, Barış; Department of Civil Engineering (2011)
This thesis examines the seismic internal retrofitting of existing deficient reinforced concrete (RC) structures by using structural steel members. Both experimental and numerical studies were performed. The strengthening methods utilized with the scope of this work are chevron braces, internal steel frames (ISFs), X-braces and column with shear plate. For this purpose, thirteen strengthened and two as built reference one bay one story portal frame specimens having 1/3 scales were tested under constant grav...
Determination of the Tensile Strength of Different Fiber Reinforced Concrete Mixtures
Ardoğa, Mehmet Kemal; Alam, Burhan; Yaman, İsmail Özgür (null; 2016-09-21)
Enhancing the tensile performance of concrete is the main advantage when fibers are added to this type of building materials. This improvement is usually measured through indirect methods like bending or split-tensile tests, in a way similar to normal concrete due to the absence of a standard tensile test for such purpose. Naturally, this type of tests does not determine the real tensile strength of the fiber reinforced concrete. Hence an important parameter, that is needed in modelling and designing proces...
Behavior of CFRP confined concrete specimens under temperature cycles and sustained loads
Erdil, Barış; Akyüz, Uğurhan; Yaman, İsmail Özgür; Department of Civil Engineering (2012)
The application of carbon fiber reinforced polymers (CFRP) is one of the effective retrofitting and strengthening methods that is used worldwide and is starting to be used in Turkey as well because they have high strength and high modulus in the fiber direction, have very low coefficient of thermal expansion when compared to concrete and steel and are known not to corrode. Since FRPs are lightweight, their mass can be neglected when compared to concrete and steel. However, before proposing this material as ...
