RISA-3D is a comprehensive structural engineering software developed by RISA Tech, Inc., designed for the analysis and design of complex 3D structures such as frames, trusses, slabs, and shells. It supports a wide range of applications, including architectural projects, bridges, industrial facilities, towers, storage tanks, and mechanical structures. The software features a user-friendly interface with CAD-like drawing tools for efficient model creation, graphical selection, spreadsheet input, and automated reporting capabilities that include material properties, shapes, quantities, and design specifications.
RISA-3D 22.01 appears to be a minor update or patch within the RISA-3D v22.0 series, released as part of the RISACore v22.0 update in early 2024. This version builds on previous releases by incorporating enhancements for structural engineers’ workflows, such as a ribbon-style interface that guides users from model conception to optimization. Key features and updates in the v22.0 lineage, which 22.01 inherits, include:
- ACI 318-19 (22) Concrete Code Support: Added compliance with the 2022 edition of ACI 318-19 for concrete design, including corrections to shear capacity calculations (Vc) per Table 22.5.5.1, axial tension capacity per Section 22.4.2, and proper transfer to integrated tools like RISAConnection.
- Enhanced Modeling Tools: Ability to move nodes with the mouse for quicker adjustments, advanced graphical tools for complex geometry, and integration with spreadsheets for direct data input/editing.
- Export and Reporting Improvements: Direct export of results spreadsheets to Excel, customizable reports with graphics and detailed outputs (e.g., unity checks for buckling-restrained braces).
- Performance Fixes: Resolutions for issues like conflicting unity check displays in 3D views, buckling-restrained brace member reporting, and code transfer accuracy.
