Cutting trusses for attic stairs.

Any field modification that involves the cutting drilling or relocation of any structural truss member or connector plate shall not be done without the approval of the truss manufacturer or a licensed design professional. My recommendation is really simple. Cutting roof trusses is possible but a structural engineer must design the plan for the truss modification to prevent roof collapse. Lay a 4x8 3 4 sheet of plywood on each end of the truss on the bottom chord spanning to the two trusses on each side of the one to be cut.

2 how much weight could the ceiling joist hold. Head off the truss to the others with double 2x10 as normally done for the floor load and sheeth the floor. Before i do can anyone help me answer the following questions. If you live in a house with engineered manufactured trusses then don t mess with them.

Don t modify cut wood trusses. 1 can the joist be cut to make room for the attic ladder.

Never cut any structural member of a truss. Replacement of these furnaces can be difficult and sometimes cannot be done without cutting or modifying a truss. If you really want to modify the framing of your attic and roof then consult with a licensed professional structural engineer. Furnaces are often located in attic areas.

Looking to take advantage of some open space in our attic and want to install an attic ladder. I wouldn t cut any trusses especially the bottom chord under tension holding the outside walls from spreading and the truss together. This would require cutting some of the ceiling joist. This is done to hold the bottom chord from pushing the wall out.
