## Reinforced Concrete Structures

### Analysis of concrete structures with fibre-reinforced polymer (FRP) rebars

- Analysis of structures with FRP rebars according to SP 63.13330.2012. Concrete and reinforced concrete structures. General rules. Appendix L.

Input data to analyse necessary reinforcement: FRP rebars

- Analysis with FRP rebars is realized for the following types of standard sections: rectangular bar, T-section with table at the top, T-section with table at the bottom, I-section, box, ring, circle, cross, angle sections, asymmetric T-section with table at the top, asymmetric T-section with table at the bottom.

Analysis with FRP rebars is realized for plate elements: shells, slabs, wall-beams.

FRP rebars may be used as longitudinal and transverse reinforcement.

- According to Appendix L to SP 63.13330.2012, FRP rebars takes only tension.

Labels for types of pilot reinforcement

- added commands to assign(cancel) PR types to(from) elements of design model in more convenient way in the list of PR types;

- when generating types of PR, for rectangular and circular sections it is possible to use the distance from section edges to reinforcement items from the set of parameters that are defined in the 'Material properties for analysis of RC structures' dialog box and referred to the element where PR type will be assigned to;

- for types of pilot reinforcement for rectangular section with arrangement of longitudinal rebars uniformly along the section edge, there is an option 'Assign symmetrically'. This option simplifies the process for assigning reinforcement for such structural elements of the model as pylons.

## Steel Structures

### Constrained torsion

- In strength analysis and general stability analysis of bending elements (in steel structures) that have shape of I-section or channel and in strength analysis when there is an axial force with bending, the program considers stresses that occur as result of deplanation (bimoment) according to sect. 8.2.1, 8.2.3, 8.4.1 and 9.1.1 SP 16.13330.2017.
