RISASection includes the ability to import your shape into RISA-3D for a full design code check. This release also includes dxf shape importing. Learn More

Making Complex Sections Simple

RISASection allows the user to define any type of complex cross section either by combining standard shapes or by defining new shapes. Multiple materials are permitted in the same section. RISASection calculates all the section properties, including the torsion constant. Sections created in RISASection may be used in RISA-3D, RISA-2D and RISAFloor.

RISASection includes many powerful editing features such as automatic stacking and aligning, unlimited UNDOs, as well as the ability to create beautiful reports with cross section graphics and much more. The program supports imperial and metric units. When creating shapes you can use the convenient “snap-to-grid” grid, or specify the coordinates of each shape directly. Of course, comprehensive online help is also included.

RISASection In-Depth

RISASectionRISASection calculates typical section properties for multi-material, built-up structural sections. Use the built-in database of standard concrete, hot rolled and cold formed steel sections, or modify standard shapes to create your own. Calculates transformed section properties for composite sections, including torsional constant. Export to RISA-3D, RISA-2D and RISAFloor.

  • Powerful align, stack and rotate tools
  • Directly edit section dimensions or use the “snap-to-grid” function
  • Import shape from a DXF file or select from an extensive database of shape types
  • Powerful calculation engine
  • English or metric units
  • Versatile reporting options
  • Multiple materials in the same section
  • Sections can be imported into RISA-3D, RISA-2D and RISAFloor to perform a code check
