Technical Information
Introduction
This specification has been produced as a general reference to support building officials, architects, engineers, builders and installers with the specification of PJT in various residential and commercial applications.
The PAVERDECK™ system is suitable for use as an exterior or interior platform for residential and commercial buildings in compliance with Building Codes in Canada and the United States. EvolutionDECK Inc. can assist builders, engineers, architects, and designers with their specific design considerations.
Materials
PJT is made from galvanized sheet steel manufactured in compliance with ASTM A653/A653M-98 Z275 (G90), with a minimum substrate thickess of 1.4mm (0.055in) and minimum yield strength of 345MPa (50ksi).
Structural Loading
The PAVERDECK™ system satisfies structural performance requirements for uniform load combinations up to 12.3 kPa (256 psf) at the specified spans. Use your applicable building code to determine your uniform load combinations for structural and service loading.
Maximum loading under Ontario Building Code
Dead load (D) = 1.6 kPa (33 psf)
Live load (L) = 4.8 kPa (100 psf)
Specified Snow/Rain load (S) = 4.0 kPa (83.5 psf)
Specified Wind load (W) = -2.0 kPa (-41 psf; 100mph)
Seismic load (E) = 1.2 kPa (25 psf, Sa(.2) = 0.66)
Maximum Clear Spans Between Beam Supports
Commercial live uniform load (100psf) = 3.1 metres (120 inches, 10 feet)
Residential live uniform load (40psf) = 4.2 metres (168 inches, 14 feet)
Maximum platform cantilever = 1.0 metre (39 inches)
Stair system maximum tread clear span = 1.2 metres (48 inches)
Stair system maximum cantilever = 305mm (12 inches)
Service Deflection at Maximum Clear Span
Service performance satisfies L/360 maximum deflection requirements:
(a) Residential live uniform load (40psf) = L/360
(b) Commercial live uniform load (100psf) = L/408
(c) Stair system 100psf live uniform loading = L/1220
Installation
PJT exterior platforms may be installed as a free-standing deck structure with or without frost footings, or attached to another structure in a similar manner as with wood structures in accordance with the standard details provided in TACBOC Standard Details (Toronto Area Chief Building Officials Committee) and as is depicted in downloadable literature.
