Define sections and inspect their capacity
COSA’s parametric builders make common sections quick to define and adjust. For arbitrary geometry, DXF import brings in the concrete boundaries, openings and reinforcement arrangement. User-defined materials and configurable safety factors keep the calculation adaptable to project requirements.
Explore resistance through 2D interaction diagrams and static 3D N–My–Mz envelope diagrams. Four views are available: three orthogonal views and one isometric view. Examine the relationship between axial force and biaxial bending, then assess the efficiency of your applied load combinations.

Handle ULS and SLS combinations in batches
COSA supports batch processing for both ULS efficiency and SLS analysis, including service stresses, strains and crack width for flexural and tensile members.
For ULS efficiency calculations, COSA can process 100,000 rows in less than a minute. Processing times vary with the CPU and section complexity. SLS batch calculations take longer.
Bring several sections into one report
Built-in multi-section Word reports combine several section calculations in one document. Keep the geometry, reinforcement, inputs and results together, reducing the effort needed to assemble the calculation package.

Make your next section check simpler
COSA brings together the calculations engineers use repeatedly: ULS resistance, SLS behaviour, crack width and interaction envelopes. Its more intuitive interface, large-batch processing and integrated reporting make it a practical FAGUS alternative for your daily section-analysis work.
