Assumptions & Limits

Profile values are treated as starting data and should be verified against the selected section table.
The default setup targets major-axis bending unless the input values are changed.
Final design still requires real load combinations, support details, and code compliance checks.

Structural Analysis for HEA 120 (Steel S235)

The HEA 120 is a high-performance structural element widely used in HEA configurations. When manufactured from Steel S235, it offers a balanced strength-to-weight ratio suitable for light-scale engineering tasks.

Load-Bearing Capacity

With a moment of inertia of 606.2 cm^4, this profile is specifically engineered to resist vertical deflection. For span checks with limits such as L/250 or L/360, HEA 120provides reliable stiffness.

Comparative Analysis

Compared to generic rectangular sections of similar mass, the HEA shape of the HEA 120optimizes material distribution toward the flanges. This gives a section modulus of 106 cm^3 and improves bending efficiency.

Methodology

The calculations performed on this page use Euler-Bernoulli beam theory. This model assumes that plane sections remain plane and is appropriate for standard slender structural members.
