design code / hong kong

Hong Kong design route.

Begin with concrete beam flexure or shear, or a steel sectional subset, then keep the remaining loading, serviceability, stability, wind, and detailing roadmap visible.

Use the current Buildings Department basis.

The public code index identifies the current editions and amendment documents. Every released calculator records its implemented edition, clauses, and limits.

ACTIONSPlanned

Dead & imposed loads

Code of Practice for Dead and Imposed Loads 2011 (2021 Edition), feeding transparent load combinations and member actions.

CONCRETELive subset

Rectangular RC beam flexure

Concrete Code 2013 (2020 Edition), amendments through April 2024, limited to fcu ≤ 45 MPa and a singly reinforced section.

Open HK concrete calculator CONCRETELive subset

RC beam shear and vertical links

Concrete Code clause 6.1.2.5 with vc, minimum/designed links, provided resistance, spacing, and maximum-stress limits.

Steel cross-section resistance

Steel Code 2011 (2023 Edition), April 2026 amendment state, limited to fully restrained Class 1–2 low-shear I/H sections.

WINDPlanned

Wind effects

Code of Practice on Wind Effects in Hong Kong 2019, including the December 2023 amendments.

Release rule

A Hong Kong calculator will not be labelled code-specific until the implemented clauses, amendment state, assumptions, limitations, worked examples, and regression tests are visible. Professional submission requirements remain outside the scope of a public quick-check site.

Read the amendment-aware scope.

The calculators implement only their stated section equations. They do not generate design actions, justify restraint or classification, or complete member stability, detailing, and submission requirements.
