Orientation of Floor Joists
Orientation of Floor Joists
(OP)
Hi,
Is there a role of thumb for orientation of wood joists in tree storey building? I am thinking that floor joists oriented parallel with roof trusses makes sense from a lateral load resisting point and this orientation usually requires less load bearing walls but usually see them oriented perpendicular to orientation of roof trusses and with more load bearing walls. Should this be just joist span/depth economic consideration or there are other - structural things to consider?
Thenks.

However, in some cases, a value engineering can include other factors, such as orienting the framing in a way to drastically reduce shear wall holdowns due to increased dead load on a shear wall.

The load on bearing walls is usually not critical. You can alwaysspace studs closer than the usual 16" o.c if needed by calculation.
