Calculation of the cross-section of the frame supports

It is not necessary to use precise calculations in calculating the cross-section of the racks for the frame of the gable walls. There are simplified formulas oriented towards the lumber produced in the country, and software products that allow you to select the material for the construction of the gable and calculate the consumption in a matter of minutes. However, without knowing the principles of calculations, it is difficult not to get confused in their algorithm, which we will now thoroughly analyze.



The principle of frame construction is to install vertical supports that determine the configuration of the wall, followed by fastening the facing material to these same posts. Craftsmen who want to install and sheathe the gables themselves only need to adhere to the generally accepted rules for constructing frame walls.

Let's assume that we calculate the dimensions of the racks for the singapore mobile database 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 houses 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.
