The above table was based on a maximum DL of 40 (kg/m 2 ), Total Wall Mass of 15 (kg/m 2 ), Floor Live Load of 1.5 (KPa), Floor Point Load of 1.8 (KN), 2. Minimum Back span = 200% of Overhang. Maximum Overhang = 30% of Back span. BEARING LENGTHS: End bearing lengths = 42 mm at end supports and 58 mm at internal supports for continuous members. Subscript values indicate the minimum additional bearing length where required to be greater than 42 mm at end supports and 58 mm at internal supports. SmartFrame Sub-floor Design Guide 17

TYPICAL LAYOUTS SmartJoist Joists (Joist hangers omitted for clarity) SmartFrame bearer Detail 1 In-line bearer and joist In-line bearer and joists can assist where ground clearance is at a minimum or allows average overall depth of the floor to be minimised but maintaining the long span capability of the joists Joist hanger SmartJoist floor joists SmartLVL Bearer CROSS SECTION Shows alternative stump/pier types, and both in-line and stacked joist systems SmartJoist SmartFrame Bearer Detail 2 Stacked bearer and joist Stacked bearer and joist allows continuous span joists to be used (supported at 3 or more supports). Continuous spans may reduce the joist depth in some circumstances.
