Enhanced User Interface
The landing page displays icons to start a new project or to view the list of existing projects including their type, status, and which projects are open for assistance*.
*Open for assistance projects are shared with your local Sika technical support for help and assistance
By accessing Preferences, the user can fully customize the units of measurement for International System or US Customary (Imperial System) units of measure.
In each project, the lateral bar is always visible and shows the project title, the design guideline in use, and the selected product catalog.
Additionally, the icons indicate the progression of the input.
Various icon colors mean the following:
- Green means that section is complete
- Grey means that section has not been opened yet
- Red means there is some issue or some data is missing in that section
Products from the selected country catalog can be chosen. Depending on the catalog and the specific project, design options include Sika® CarboDur® plates, SikaWrap® fabrics, and near surface-mounted (NSM) profiles.
The software provides real-time calculations. The results are shown in the Strengthening step, with all relevant figures and numbers displayed and fully controlled by the user.
A full print out in PDF is generated after the project is completed. The print out contains:

Confinement
The Confinement module allows the design of structural strengthening through fiber reinforced polymer (FRP) confinement for reinforced concrete (RC) sections subjected to biaxial bending moments. This module facilitates the analysis of columns subjected simultaneously to axial loads and bending moments acting in two orthogonal directions.
It is possible to design FRP confinement strengthening for rectangular and circular RC sections.
The load input process is straightforward, and the section's use ratio under various design loads is displayed instantly - including ultimate limit state (ULS), serviceability, and fire.
The design of strengthening is carried out quickly, with the outcomes shown instantly.
When the selected design guideline is based on Eurocodes, the fire resistance of the RC section can be evaluated using the “Isotherm 500° C method”. Furthermore, it is possible to track the evolution of isotherms over time throughout a fire event.
Flexural
The Flexural module allows the design of fiber reinforced polymer (FRP) systems for reinforced concrete (RC) sections subjected to both positive and negative bending moments, including scenarios involving also axial loads.
It is possible to use rectangular, T-shaped, inverted T, double T-shaped, or slab sections.
It is possible to use normal and prestressed steel.
The load input process is straightforward, and the section's use ratio under various design loads is displayed instantly - including ultimate limit state (ULS), serviceability, and fire.
For the design of the section, it is also possible to consider an axial load (i.e. inclined beams).
Strengthening can be designed through either externally bonded reinforcement (Sika® CarboDur® or SikaWrap®) or NSM profiles (Sika® CarboDur® NSM).
Furthermore, the FRP can be applied not only to the soffit but also to the lateral sides of the beam, with the results displayed immediately.
When the selected design guideline is based on Eurocodes, the fire resistance of the RC section subjected to bending moments can be evaluated using the “Isotherm 500° C method”. Furthermore, it is possible to track the evolution of isotherms over time throughout a fire event.
Shear
The Shear module allows the design of fiber reinforced polymer (FRP) systems for reinforced concrete (RC) sections subjected to shear forces.
It is possible to use rectangular or T-shaped sections.
The load input process is straightforward, and the section's use ratio under various design loads is displayed instantly - including ultimate limit state (ULS), serviceability, and fire.
For the design of the section, it is also possible to consider an axial load (i.e. inclined beams).
Strengthening can be designed through either externally bonded reinforcement SikaWrap® or preformed profiles (only in case of lateral wrapping).
Furthermore, the FRP can be applied not only to the soffit but also to the lateral sides of the beam, with the results displayed immediately.
When the selected design guideline is based on Eurocodes, the fire resistance of the RC section subjected to bending moments can be evaluated using the “Isotherm 500° C method”. Furthermore, it is possible to track the evolution of isotherms over time throughout a fire event.
