Compressive behavior of steel-fiber reinforced concrete in Annex L of new Eurocode 2

نویسندگان

چکیده

This paper describes the model for compressive stress-strain behavior of steel fiber-reinforced concrete (SFRC) in Annex L new Eurocode 2 (version 2022-05, EC2), developed within CEN TC250/SC2/WG1/TG2 – Fiber reinforced concrete. The uses functions obtained from correlations with an extensive database comprised 197 well-documented SFRC tests and 484 flexural tests. We detailedly explain derive strain values parabola-rectangle ULS L. In addition, we also use to provide a link between performance classes EC2, which allows complete definition any particular SFRC. Likewise, each class, is mainly advantageous stronger classes. Finally, give example showing enhancement strength ductility composite steel-SFRC section endorsed model, results 15% 100%, respectively.

Compressive Behavior of Fiber-Reinforced Concrete with End-Hooked Steel Fibers

In this paper, the compressive behavior of fiber-reinforced concrete with end-hooked steel fibers has been investigated through a uniaxial compression test in which the variables were concrete compressive strength, fiber volumetric ratio, and fiber aspect ratio (length to diameter). In order to minimize the effect of specimen size on fiber distribution, 48 cylinder specimens 150 mm in diameter ...

Some Studies on Steel Fiber Reinforced Concrete

Fibres are generally used as resistance of cracking and strengthening of concrete. In this project, I am going to carry out test on steel fibre reinforced concrete to check the influence of fibres on flexural strength of concrete. According to various research papers, it has been found that steel fibres give the maximum strength in comparison to glass and polypropylene fibres. Hence, in this pr...

Experimental Investigation of Behavior of Glass Fiber Reinforced Concrete (GFRC)

The paper presents the results of casting and testing of 264 GFRC specimens. The glass fibers were 25 mm long, with the aspect ratio (L/D) ranging between 1250 and 3570. The parameters studied were the ratio (by weight) of fibers to cement, i.e. F/C=0%, 1.5%, 3%, and 4.5%, and the ratio of coarse to fine aggregates (gravel to sand), i.e. G/S=1.1, 0.7 and 0.2. In total, 12 mix designs were selec...
