The choice of distance between racks is influenced by:

Let's assume that we calculate the dimensions of the racks for the gables of a private residential building up to 9 m wide, two stories high or one story high with an attic. The maximum ceiling height should not exceed 2.4 m. For an attic floor, the ceiling height is considered to be the distance from the subfloor to the ceiling beam, which can be a rafter truss crossbar.

In most cases, there is no point in performing highly complex calculations in low-rise construction. It is better to use the existing experience of builders who have been designing and constructing frame philippines mobile database for many years. For example, there is a table from Norwegian engineers with recommended timber sizes for constructing frame walls.

If the width of the building is more than 10 m, and the height of the central pillar of the frame gable is more than 3 m, then Norwegian builders do not have the right to independently determine the cross-section of building materials for frame structures. This work must be carried out by a design engineer, taking into account the number of storeys of the building and local conditions.

We do not have such strict requirements for the design and calculation procedure. The support section for a high and wide pediment can be calculated independently. They are calculated as compressed structural elements, i.e. they are checked only for resistance to compression.

The minimum size of the stand is considered to be 100×100 mm. If a support of this size does not meet the technical requirements, one of the edges of the bar is increased and the resistance to bending is checked again. If necessary, the calculation process is repeated until a section of lumber is obtained that can easily withstand the load. Do not forget that a paired board can be used instead of a bar.

Step of installation of racks
It should be remembered that with an increase in the number of frame supports, it becomes possible to reduce the cross-section of the lumber used for their construction. This does not mean that instead of a frame, you can build a "palisade" from a thin bar, since in the overwhelming majority of situations, the gable frame must resist vertical compressive force, hold the door and window frames.
