FRCcalc is a software developed for the analysis of structural members in fibre reinforced concrete (FRC) with or without conventional steel reinforcements. The analysis is performed at a cross section level of a member of 2D plane frame or shell structures. The members can be submitted to bending, shear and axial force. The ultimate and serviceability limit state safety verifications (ULS and SLS, respectively) of structural members are performed by FRCcalc. The software adopts the recommendations and design guidelines of Model Code 2010 .

FRCcalc is guided to the analysis of rectangular cross-sections with or without conventional passive steel reinforcements, submitted to axial, bending and shear forces.
A main feature of the software is the possibility to run a comparative analysis between FRC and conventionally reinforced concrete (RC) cross-sections or even hybrid reinforcement (conventional with fibre reinforcements, herein designated by the acronym R/FRC), which was implemented to assess the improvement provided by the addition of fibre reinforcement to concrete and to assess the potentialities of replacing conventional reinforcement by fibers.
The software allows to perform the following analysis, for FRC, RC and R/FRC members:
- Ultimate flexural capacity;
- Evaluation of the moment vs. curvature relationship at Ultimate Limit States (ULS);
- Ultimate shear capacity;
- Evaluation of design crack width;
- Determination of moment vs. design crack width relationship at Serviceability Limit States (SLS);
- Evaluation of stress limitation criteria at SLS.
The good predictive performance of the models implemented in FRCcalc has been demonstrated in several technical and scientific publication in this regard , .

FRCcalc is being continuously updated in order to add new functionalities and improvements to the design tool.
It is guaranteed the release of new versions of the FRCcalc in case of changes in the guidelines and codes on which the software is based. A continuous monitoring of the most recent and significant research projects and published peer-reviewed articles regarding fibre reinforced concretes structures can also lead to the release of new updated versions of FRCcalc.
A new version of FRCcalc is planned to be released with the upcoming design guidelines of the new Eurocode 2 – Annex L : “Steel Fibre Reinforced Concrete Structures”.
