Cross-Sectional Properties & Reinforcement Database Tables

This module presents comprehensive cross-sectional property tables for reinforcing steel bars under different international regulatory frameworks. The data matrix maps nominal bar diameters, total cross-sectional areas (A_s), and unit weights according to each specified design standard.

EN 10080 / ISO Metric Table: European metric bar designations ⌀8 mm to ⌀40 mm paired with ductility classes (Class A, B, C). Covers nominal diameters, cross-sectional areas (mm²), and unit weights (kg/m) for compliance with EN 1992-1-1 detailing rules on minimum reinforcement ratio and maximum bar spacing.
ASTM A615 Table: Standard US bar sizes No. 3 to No. 18 with corresponding nominal diameters (in/mm), cross-sectional areas (in²/mm²), and unit weights (lb/ft, kg/m). Covers Grade 60 (f_y = 420 MPa) and Grade 75 (f_y = 520 MPa) for evaluation of minimum reinforcement ratios (ρ_min) and spacing limits per ACI 318.
IS 1786 Table: Nominal dimensions and cross-sectional areas for Indian standard high-yield strength deformed (HYSD) bars — Fe 415, Fe 500, Fe 550, and Fe 600. Includes unit weights for immediate checking of tension and compression reinforcement areas under IS 456:2000 flexural and shear design provisions.
