Included are a series of representative roof truss span tables that will give you an idea of the truss spans available for a particular load condition load duration lumber type and truss configuration.

Is the leading supplier of connector plates truss manufacturing equipment design software and engineering services for the worldwide component industry. In some instances floor trusses could be used to eliminate or reduce the excavation costs associated with sloping blocks. Floor performance spacing span note hopleys trusses this table may also be used for wind uplift to a maximum of 0 4 kpa with suitable lateral restraints. To find maximum clear span for a given truss depth in a given loading condition refer to the bottom line of spans shown for that particular truss depth.

Span tables below illustrate common combinations of the multiple variables available. Standard floor types dead load 0 75 kpa i e. Here wind load governs ie in excess of 0 4 kpa the span shall be reduced. Boxspan residential span tables.

Basic lumber design values are f 2000 psi f 1100 psi f 2000 psi e 1 800 000 psi duration of load 1 00. In some cases the use of floor trusses may eliminate the need to use costly steel beams ideal for sloping blocks. Bottom chord dead load 5 psf.
