hong kong code design
Choose Concrete Code or Steel Code.
The Hong Kong route is divided by material and tied to the edition and amendment state stated on each page. Every calculator is a bounded arithmetic check rather than a Buildings Department approval calculation.
material routes
Hong Kong calculators by Code family.
Select Concrete Code or Steel Code, then use section properties and buildable reinforcement arrangements to iterate the member design.
Reinforced concrete
Beam and one-way slab checks using reinforcement formats used on drawings.
- RC beam flexural resistanceEnter tension reinforcement as a count and bar diameter.
- RC beam shear resistanceEnter longitudinal bars and vertical-link arrangement.
- One-way RC slab flexure and shearEnter principal and secondary diameter and spacing.
Structural steel
Low-shear, fully restrained section arithmetic with explicit omitted member checks.
- Steel section resistanceUse verified section properties, classification, and design strength.
Use the section-property calculators while changing dimensions, then return to the Concrete Code or Steel Code check. The live tools do not select a member automatically.
declared limits
Read the edition and scope on every calculator.
Loading combinations, analysis, serviceability, durability, fire, detailing, connections, omitted stability and interaction checks, drawing coordination, submissions, and professional review remain separate unless a calculator explicitly includes them.
