Again this house has the same width dimension but it has 2 levels.

Roof load for 28 x 24 hip.

The total load is 4 000 pounds. For the initial calculation f can be estimated at 1 000. 10 psf x 6ft 60 pounds per lineal foot. In general terms perhaps the forces on the hip rafter jack rafter connection consist of the tributary roof load transfered by the jack rafter plus a force along the axis of the jack rafter for our purposes the force along the axis of the jack rafter has a vertical component that supports the hip rafter the method of computing this supporting force and the resulting stress and deflection.

Now the example formula is 4 000 1 000 bd 2 9 x 10. 20 psf x 6ft 120 pounds per lineal foot. Structures such as sheds or barns can be frames with rafters every 24 again make sure to consult local codes. F stands for the beam s fiber strength in bending which depends on the species of wood.

Loads are contributed. If your project had a rafter length of 8 or less a safe and strong method is to use 2x8 framed 16 on center. Load limits on the roof of a building. Minus ridge thickness to allow for ridge becoming pole plate roof peak will be slightly higher ridge thick must be same.

In the example the beam spans the 10 foot width of the roof. Hip roof a hip roof is a rectangular roof that slopes on all four sides.

In hip roof designs all four exterior walls support the ends of roof rafters so all exterior walls bear a weight load from the roof above them. In order to stay intact and in place a roof must be able to resist loads both permanent and temporary that are pushing. These walls are supporting the roof rafter ends bearing their weight load.

Roofs are under a lot of pressure. Not helpful 0 helpful 2. This calculator will help you estimate hip roof parameters including rafters and roof area person outline anton schedule 2011 08 29 17 53 20 one of users asked us to create calculator which will help him estimate hip roof parameters like rafter s lengths roof rise and roof area. 10 psf x 14ft 140 pounds per lineal foot.

A regular hip has equal slopes on all sides while an irregular hip has different slopes on the main roof and hip end roof. The four exterior walls of buildings with a hip roof usually tend to be load bearing walls. There are no gable ends on a building with a hip roof. Enter the extension wall length into wall length and double the extension wall width then minus ridge thickness into the wall width entries.
