Four Point Bending Test

Nowadays, retroftting reinforced concrete with FRP fbers is regarded as a globally signifcant issue. In reinforced concrete beam, the shear failure mode is more dangerous than fexural failure mode. Because this thin and sudden mode occurs without any pre-warning, diagonal shear cracks are wider than fexural cracks and preventing their expansion is rather diffcult. In the present study, the concrete beams are retroftted with GFRP fbers through a common method. Then, the beams have four- point bending test until the premature failure occurs. This phenomenon is relatively prevented through retroftting along the shear. The failure of beams are examined here.Journal of the Institute of Engineering, 2015, 11(1): 12-19

Maximum Capacity

Need for the use of reinforced concrete in housing construction will increase along with the rapid population growth. This increases the need for steel reinforcement as a major component. The increase in need for steel reinforcement will trigger a price increase so that it becomes expensive and scarce. Iron ore as a raw material for making steel reinforcement is a mineral that can not be renewed. Therefore, efforts to use alternatives to steel reinforcement in concrete. Bamboo has good mechanical properties and a high ratio between strength and weight. Bamboo has a tensile strength is high, between 100-400 MPa, nearly matching the tensile strength equivalent to steel reinforcement ½ to ¼ of iron ultimate voltage (Widjaja, 2001) and (Surjokusumo and Nugroho, 1993) showed similar results and by the Moriscos, 1996 that the tensile strength of bamboo can reach 1280 kg / cm2. Bamboo can be used as the material of reinforced concrete. This study aims to determine the capacity of the bending beam with reinforcement of bamboo, bamboo reinforced beam deflection capacity. This experiment is a concrete beam bending test. The results showed that bamboo reinforced concrete beam has a maximum capacity reached 56.61% of the maximum capacity of steel reinforced concrete.

Four Point Bending Test

The paper deals with an investigation of tensile properties of concrete and fibre reinforced concrete using the test in uniaxial tension. This arrangement is technically more difficult compared to the commonly used bending test, but allows easier determination of strength-deformation parameters of material. The advantage of the test is the possibility of direct analysis of the post-peak part of the stress-strain diagram in tension. The article describes the recommended test arrangement and analyzes methodology of loading. Attention is focused on the critical phase of the loading process and subsequent evaluation of results. In the experimental research was compared strength and corresponding strain of specific fibre reinforced concrete, obtained in three-point and four-point bending test, and the uniaxial tension test. The results of this comparative study are presented in the conclusion.

The Impact

This paper discusses the feasibility of an innovative anchoring element which is designed to be integrated into the volume of an ultra-thin coffered façade panel made of textile reinforced concrete and to not increase its external dimensions. The first part of the article describes the composition and shape of the façade panel and focuses on the manufacturing of the composite anchoring element made of carbon technical textile penetrated with polymer matrix which is intentionally identical composition as in the case of the façade panel reinforcement. The second part of the article focuses on the behavior of the composite anchoring element and its effect on its surroundings during the mechanical loading of the façade panel. Specimens of the coffered façade panel with integrated anchoring elements were subjected to four-point bending test to determine the impact of the anchoring elements on the façade panel flexural tensile strength and type of failure. Additional specimens were tested to determine the load-bearing capacity of the anchoring elements.
