MULTI-JOIST SPECIFICATION
clear
 

Working Moment of Resistance for all lengths:
5 1 kNm F of S = 2
Ultimate figure, an average derived from tests 10.1 kNm

Recommended Maximum Tie Load:
3048 kg F of S = 2
Ultimate figure, an average derived from tests 6096 kg
Deflections when the Multi-joist has a uniformly distributed load developing a bending moment
of 5.1 kNm

Average measured deflection of a 1270
Multi-joist spanning 1118mm = 3.56 mm

Average measured deflection of a 1830
Multi-joist spanning 1676 mm = 5.59 mm

Average measured deflection of a 2440
Multi-joist spanning 2286 mm = 7.62 mm

In order to limit deflection, it is recommended that the bending moment across joint plates when Multi-joists are bolted together does not exceed 3.0 kNm
