Some of the commonly used types are shown below.

How long can floor trusses span. Long span trusses are 60' or greater in length. One of the biggest advantages of floor trusses is that they can span further than conventional framing (i.e. Basic lumber design values are f =2000 psi f =1100 psi f =2000 psi e=1,800,000 psi duration of load = 1.00.

Scissors trusses, the code (ibc 2303.4. P 2 access voids for services can be designed and located to specified requirements. While longer trusses may be “wobbly” as they are lifted off of the ground and onto the bearing walls, once they are properly braced, the truss system is extremely strong.

Floor truss information just as with our roof trusses the floors are designed and engineered on a truss by truss basis which allows us to A roof truss can span up to 80′ without support, however in any home that distance would be impractical and incredibly costly. Pryda floor and rafter truss systems have been used with outstanding results for over 15 years by designers and builders.

Second, design the trusses for the 8' o.c. Below is a chart that we use for quick reference to match floor truss height and spacing with any given span. Maximum deflection is limited by l/360 or l/480 under live load.

Spacing of trusses are center to center (in inches). At 16 inch spacing, 15 feet 2 inches and 13 feet 3 inches at 24 inch spacing. A long span truss can pose a greater risk to installers because the dimensions and weight of the truss itself can create instability, buckling and collapse of the truss if it is not handled, installed and braced properly.

But the trusses may have to be 2 or 3 plies to work. 3 strongback beams are fixed to the vertical webs of trusses to ensure even sharing of live loads. 1ryda floor trusses can be designed to cantilever around voids and stairwells, saving on support beams.

Trusses are designed to span spaces without interior supports, and spans of up to 40′ are the most common in today’s homes. How wide can floor joists span? In the engineering and construction industry, any truss spanning more than 60 feet is considered to be “long span”, thus requiring engineering consideration (per international building code (ibc) 2015 section 2303.4, “trusses” [for design of]).
