How to Use
Switching section tables
Use the buttons in "Select steel section type" to switch between 13 types of JIS steel sections.
Cross-section drawing
Click a designation (e.g. H-200×100×5.5×8) to display its cross-section drawing.
Row selection (marker)
Click a row to highlight it for comparison. Click again to deselect.
Filter by required Zx / Zy
Open "Required Section Modulus Calculator" and enter the required Zx or Zy [cm³]. Sections that satisfy the requirement are highlighted in yellow.
Calculate required Zx from bending moment
Enter the design bending moment Mx [kN·m], steel grade (SN400/SS400 or SN490) and load duration; the required Zx is calculated automatically. * Lateral-torsional buckling is not considered.
Text size
Use the S / M / L buttons at the top right to change the table text size (saved in your browser).
