1Why we built StructFlow
Research on high-strength reinforced concrete has produced reliable analysis methods, but they mostly exist as research programs: they require a specific operating system, have strict input formats, and are hard to update and trace. StructFlow organizes these methods into cloud tools engineers can use every day, with mechanical results that agree with the original research program.
2Five tools
Five tools are available at launch: rectangular column biaxial analysis, structural wall biaxial analysis, circular column P–M, moment–curvature analysis, and cantilever retaining wall design. Each tool lets you enter or import a section, see results instantly, and export a calculation report.

3Verified by professors
The calculation core derives from New RC research and has been verified by professors. The cloud version is compared point by point with the actual output of the original research program, and every update must pass all verification again before release. For the comparison results, see the validation report.
4Four languages
The interface, calculation reports, and verification code emails are available in Traditional Chinese, English, Japanese, and Korean, so international teams and overseas reviewers can work from the same results.
