Calculating the weight of a building is a pretty simple activity. Therefore, finding out how much a frame house weighs is not a problem. This takes into account the thickness of the walls, calculates the width and length, determines the type of supporting structure. And the weight of the house, up to calculating the load on the foundation.
What to consider when calculating
To get all the necessary data and as a result, to calculate how much the house weighs, it will be enough to take into account:
- With a standard wall thickness (150 mm), the specific gravity of a building wall with an insulating layer is 30-50 kg / m 2 .
- Wooden beams are suitable for overlapping the attic of a frame house, which reduces the weight of the structure. The overlap density in this case is 200 kg / m 3 . The weight of the structure is 75-105 kg / m 2 .
The proportion of roofing
It remains to deal with the roofing and determine how much the house weighs. Here, the type of the roof itself takes part in the calculation:
- steel sheet - 20-30 kg / m 2 ;
- ruberoid - 30-30 kg / m 2 ;
- slate - 30-40 kg / m 2 ;
- classic tile coating, but do not confuse it with metal tile, which is sheet steel - 60-80 kg / m 2 .
When calculating how much the house weighs, be sure to take into account the weight of the snow cover. For the southern part of the country it is up to 95 kg / m 2 , for the central regions - 145-195 kg / m 2 , for the Far North - over 200 kg / m 2 . At the same time, the national average is formed, amounting to 155 kg / m 2 of the roof.
Given all the parameters, it is determined that the average weight of the house is 365 kilograms per 1 square meter. And this, compared with the weight of a five-story building (2600 tons), is ten times less. You can imagine how much a five-story house weighs.
Calculation of area and weight
This is an integral stage of calculations. The area of the foundation, equal to how the dimensions of the bearing surface depend on the type of material that is used during construction.
So, the foundation on piles is calculated according to one principle, while the columnar foundation is completely different.
For a reliable construction of a frame house, an ordinary columnar foundation is sufficient, as for a standard small wooden house.
The final construction estimate is calculated as relatively small, even taking into account thick walls.
Foundation Weight Calculation Example
Carrying out such calculations, an example is indispensable. Therefore, imagine that for the future foundation, tables were taken with a diameter of 0.2 m, with a height of 2.9 m, and a depth of 1.5 m.
The calculation of the reference area, which in this embodiment is 314 cm 2 , the volume is 0.065 cm 3 and the weight is 143 kg.
According to the condition, the length of the wall should be 30 m - this is a number indicating the total length of all the walls of the house. When installing support columns every 100 cm, it turns out that 30 columns are required to construct a reliable support under the house. So, the total weight of the foundation will be 9420 square meters, which is 4.29 tons in weight.
To calculate the total ground load, you need to determine how much the house weighs. This number is added to the weight of the foundation and the amount is divided by the supporting area of the structure.
As you can see, it is not so difficult to calculate how much the frame house weighs, to determine the maximum load on the soil and the bearing capacity of the foundation, and there is no need for the services of a design bureau.
