چکیده
In the present study, performance of Reinforced Concrete (RC) beams which were strengthened with Ultra High Performance Fiber (UHPFRC) and dowels at interface was investigated. RC a length 2.2 m UHPFRC layers tensile side. Before application layers, between roughened. During testing, slips recorded using Linear Variable Differential Transformers (LVDTs). The tested under four-point flexural test. results study indicated that reduce interface, delay formation cracks result in higher load carrying capacity.

Damage Simulation of High Performance Fiber Reinforced Concrete
The simulation of damage and failure in short fiber reinforced composites like high performance hybrid-fiber reinforced cement composites is still a challenging task, due to the richness of failure mechanisms introduced by fibers on the mesoscale of the material. Randomly oriented, hooked steel fibers, like the Baekaert Dramix® fibers, sustainable modify the macroscopic failure behavior of the ...
متن کاملFeasibility of Reducing the Fiber Content in Ultra-High-Performance Fiber-Reinforced Concrete under Flexure
In this study, the flexural behavior of ultra-high-performance fiber-reinforced concrete (UHPFRC) is examined as a function of fiber length and volume fraction. Straight steel fiber with three different lengths (lf) of 13, 19.5, and 30 mm and four different volume fractions (vf) of 0.5%, 1.0%, 1.5%, and 2.0% are considered. Test results show that post-cracking flexural properties of UHPFRC, suc...
متن کاملElectrical and Self-Sensing Properties of Ultra-High-Performance Fiber-Reinforced Concrete with Carbon Nanotubes
This study examined the electrical and self-sensing capacities of ultra-high-performance fiber-reinforced concrete (UHPFRC) with and without carbon nanotubes (CNTs). For this, the effects of steel fiber content, orientation, and pore water content on the electrical and piezoresistive properties of UHPFRC without CNTs were first evaluated. Then, the effect of CNT content on the self-sensing capa...
متن کاملExperimental 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...
