Summary
- No single universal load value
- Consult Florida design manual tables
- Miami Metal Deck provides span calculations
The Florida design manuals do not prescribe a single fixed maximum live load per span for Type B structural performance. Instead, allowable live load capacity is determined from code tables, manufacturer test data, and span-dependent design checks. Designers use the Florida Building Code, referenced manuals, and ASCE 7 guidance to convert required live loads (psf) into allowable per-span values for a given deck profile, support spacing, and deflection limit. Miami Metal Deck reviews these criteria to deliver code-compliant specifications.
Why there is no single maximum value
Type B structural performance is a classification that depends on deck geometry, material gauge, span length, support conditions, and whether composite action is achieved. Florida manuals present tabulated allowable loads by span and deflection criteria rather than a single number because capacity changes dramatically with those variables.
Typical design practice references minimum live loads from ASCE 7 (for example many occupied floors use 40 psf) and then checks whether the chosen deck and span meet strength and serviceability limits. For metal deck projects you must check both strength (ultimate load) and deflection (L/240, L/360, or project-specific limits) per the Florida Building Code and contract documents.
How to determine the maximum live load per span
1) Identify applicable code and Florida design manual edition. 2) Select the Type B deck profile and material gauge. 3) Use manufacturer tables or engineering analysis to find allowable live load by span. 4) Verify strength and deflection under required load combinations. 5) Document results in calculations and shop drawings for approval.
Engineering verification typically converts uniform live load intensity (psf) to an equivalent per-span load (plf) based on tributary width and span geometry. Where tables do not cover a specific span, a licensed structural engineer performs a stamped calculation to establish allowable span capacity for Type B performance.
Why choose Miami Metal Deck for span calculations
Miami Metal Deck offers experienced in-house engineering reviews and documentation tailored to Florida code requirements. We prepare stamped calculations, shop drawings, and supporting test data to demonstrate that your Type B deck meets the specified live load per span and deflection criteria.
Our differentiators include manufacturer-backed load tables, project-specific span analysis, QA during fabrication, and field verification to confirm as-built performance. We align results with Florida design manual references so architects and structural engineers can approve designs with confidence.
Practical next steps for your project
For any project requiring Type B structural performance, begin by specifying the deck profile and design live loads in the contract documents, then request span-specific load tables or stamped calculations. Miami Metal Deck provides these services to ensure your metal deck meets Florida design manual requirements and performs reliably under the required live loads.
