![]() The following table, lists the main formulas, related to the mechanical properties of the I/H section (also called double-tee section). The I-section, would have considerably higher radius of gyration, particularly around its x-x axis, because much of its cross-sectional area is located far from the centroid, at the two flanges. Circle is the shape with minimum radius of gyration, compared to any other section with the same area A. Small radius indicates a more compact cross-section. It describes how far from centroid the area is distributed. The dimensions of radius of gyration are. Where I the moment of inertia of the cross-section about the same axis and A its area. Please use consistent units for all input. The calculated results will have the same units as your input. Enter the shape dimensions h, b, t f and t w below, taking into account the provided drawing. Bending Moment Calculator Calculate bending moment & shear force for simply supported beam. This tool calculates the moment of inertia I (second moment of area) of a zeta section (Z-section). Calculator for Moving Load Analysis To determine Absolute Max. Radius of gyration R_g of a cross-section, relative to an axis, is given by the formula: Calculate Principal Stress, Maximum shear stress and the their planes. Properties of normal flange I profile steel beams.ĭimensions and static parameters of steel angles with equal legs - metric units.ĭimensions and static parameters of steel angles with unequal legs - imperial units.ĭimensions of American Wide Flange Beams ASTM A6 (or W-Beams) - Imperial units.The area A and the perimeter P, of an I/H cross-section, can be found with the next formulas: mass of object, it's shape and relative point of rotation - the Radius of Gyration.
