Steel Designer

Steel Design (HK COP 2011) is a member checking tool for structural and civil engineers. It provides rapid analysis of steel member capacities based on the Hong Kong Code of Practice for the Structural Use of Steel 2011 (HK COP 2011).

This app is intended for use during site visits, meetings, or for preliminary sizing at your desk, providing an offline alternative to reference tables and spreadsheets.

Calculation Transparency
To ensure reliability, the app provides a full step-by-step breakdown of calculations. It displays the specific equations, variables, and code clauses used for every check, functioning as a digital calculation pad rather than a "black box" tool.

Core Features:

Capacity Checks: Instant utilization checks for combined axial and bending forces, and shear.

Buckling Analysis: Lateral Torsional Buckling (LTB) checks and slenderness calculations.

Section Classification: Automatic determination of Section Class (1 to 4) based on yield strength and geometry ratios.

Offline Access: All features and databases are available without an internet connection.
