Integrated model for predicting the flexural capacity of concrete elements reinforced with non-corrodible discrete reinforcements

Polypropylene fibres (PP) have been used mainly in non-structural applications for limiting crack width due to shrinkage effects of cement-based materials. Being insusceptible to corrosion, PP fibres can also be regarded as viable discrete reinforcement elements for the production of thin concrete elements. The relatively low elasticity modulus, tensile strength and almost frictional-based reinforcing nature of PP fibres have been…

Urban furniture in fiber reinforcemenet concrete with high durability

Within the scope of the “NG_TPfib” R&D project, Exporplás and CiviTest have, in the recent past, developed a new typology of polypropylene fibers for the production of urban furniture of high durability by eliminating conventional steel reinforcements susceptive to corrosion. This reinforcement replacement strategy also allows the development of lighter and more elegant urban furniture with complex geometries at competitive…

Appraisal of MC2010 shear resistance approaches coupled with a residual flexural strength prediction model

In the present work the predictive performance of the two approaches proposed by Model Code 2010 for the evaluation of the shear capacity of fiber reinforced concrete (FRC) elements flexurally reinforced with conventional steel bars is assessed considering a database (DBs) constituted by 80 FRC beams do not including conventional transverse reinforcements. The accuracy of these shear models is evaluated…

FRCcalc – Software for design of fiber reinforced concrete elements according to MC2010 recommendations

A new software, denominated FRCcalc, was developed for the analysis and design of fiber reinforced concrete (FRC) members based on the recommendations and design guidelines of MC2010. The software is guided for the analysis of FRC cross-sections with and without conventional steel reinforcements, submitted to bending and shear, in order to assess the ultimate and serviceability limit state safety verifications…
