Table 1. For a member to be in continuous span the smallest span must be greater than 80% of the other span/s or equal to them. 2. D3(Nov 2005). Interactive Span Table If you are considering using JJI-Joists in your construction project, use our Interactive Span Table to quickly identify the size and specification that you will require. The shapes of the trusses, beams and columns are visible everywhere in the house, throughout the foyer, master bedroom, great room, porch and kitchen. Fewer posts on upper level decks are typically more desirable to the occupants and this drives the use of larger framing materials for longer spans. Certainly, the track could brace the top flange if it possessed sufficient strength and stiffness. The beam is laterally supported for its entire length. Beam spans in the Span Tables are for wind loads up to N3 as described in AS4055 Wind Loads for Houses. Select the span carried by the beam across the top of the table. The result – a 40-60% lighter beam with the strength of steel and the versatility of timber. During the construction of the Meadow House, I used a technique that I call the hollow box beam to create a signature look that emphasized structure. �{�L-n������O�w��0�{��/�u����ݾ#�A�V���z�H��N�� ܍߿��%a%�j��~���~�K����Sa�p�^�8"�; 6�TE��3��m���OX���l4��������oW�����XdqJ �����_o��צ��Bޯ�����:�F��|lsD7�+t�׭��i%���G�A��Wä��:K��)��oΏ��p������u���k��#��� �4������'H�KosL ����o��������M�)~��t߇T?�����l�cƿ#�Y���K��t�+��#��U��ڇJ�����[������-{���#�������w�{ѧ7�G�?�������_��_��[Oߨ��_��d? deep rectangular and Table 9.1 in Span Tables for Joists and Rafters (Figure 5) gives a required compression value of 237 psi for a span of 16 feet and bearing length of 1.5 inches. 40/10=50psf: Yield Strength of Steel (KSI) e.g. 2.

They can also be used in single span applications, although an unbalanced beam is more efficient for this use. My thinking was that the track wouldn't add all that much extra lateral stiffness to the top 1/3 or so of the box beam so long as the box beam were behaving compositely about the weak axis.
