Application of high performance polypropylene fibers in concrete lining of water tunnels
Kiachehr Behfarnia,Amir Behravan +1 more
TL;DR: In this paper, the application of high performance polypropylene fibers (HPP fibers) in concrete lining of water tunnels, was investigated experimentally, and the results showed that the HPP fibers were not effective in compressive strength when compared to steel fibers, but the effects of HPP fiber on tensile strength, flexural strength, toughness and energy absorption of concrete were significant.

Comparison of the structural behavior of reinforced concrete and steel fiber reinforced concrete tunnel segmental joints
TL;DR: In this paper, the performance-based engineering (PBE) concept was introduced to assess the robustness of the tested segmental joints with steel fiber reinforced concrete (SFRC) joints.
Journal ArticleDOI
Plastic fibres as the only reinforcement for flat suspended slabs: Experimental investigation and numerical simulation
TL;DR: In this paper, the structural response of hyperstatic concrete flat suspended slabs reinforced only with structural plastic macro-fibres was studied. And the results showed that the slabs tested maintained a high load level after cracking showing a ductile behaviour with great stress redistribution capacity.
Journal ArticleDOI
Fibre distribution in macro-plastic fibre reinforced concrete slab-panels
TL;DR: In this article, the influence of flowability and wall-effects of the formwork in the orientation pattern of macro-plastic fibres was studied, and the results showed that plastic fibres tend to be oriented parallel to the walls or surfaces of a formwork and perpendicular to the flow direction for a free surface flow.
Journal ArticleDOI
Application of constitutive models in European codes to RC–FRC
TL;DR: In this article, the structural behavior of RC-FRC elements with steel fibers and with plastic fibers is compared and a numerical simulation is performed to evaluate their differences in terms of the structural behaviour predicted and measured in an experimental program.
