1. General information
1.1. Investment design
The structure is family house dimensions 12 x 8,2 m with basement ground floor and garret.
Main target in design
was low energy
consumption
family residence.
2. Bearing system
2.1. General descriptionThe structure is family house with: concrete basement, wooden structure with
steel frame of the ground
floor and wooden structure
of the garret.
Outside walls as timber frame with the final configuration:
1. Contact facade: 0,6 cm
2. Fasade plate: Agepan THD 6 cm
3. Timber frame structure with
blown-in wood fiber insulation: 16 cm
4. OSB plate: 1,5 cm
5. Instalation channel with
blown-in wood fiber insulation: 5 cm
6. 2 layers of gypsum plaster board: 2 x 1,25 cm
2. Bearing system
3. Actions on structure
Applied actions on structures for the calculation:
1. Dead load
2. Live load p = 2.0 kN/m2
3. Snow s0 = 1.27 kN/m2
4. Wind on roof w0 = 0.16 kN/m2
5. Wind on wall w0 = 0.45 kN/m2
6. Acceleration of the foundation 0,20 g
4. Erection
Wooden structure and steel reinforcement of the ground floor is placed on the reinfored concrete plate (15 cm) covered with the hydroinsulation (1 cm), followed with thermal insulation XPS (20cm), PE foil and reinfored concrete plate (20 cm).
Load carrying outside walls were prefabricated frames covered with OSB plates on one side.
Wooden structure of the garret and roof.
5. Technical parameters
Ground plan size: 12 x 8,2 m
Number of above-ground floors: 2
Type of roof construction: 35º
Construction of external walls: Timber frame with OSB on the one side and fasade plates on the other side filled with the blown-in wood fiber insulation.
Reinforcement of the ground floor: 3 x steel beam on two steel columns for the earthquake loading, HEA 160, S235JR
Thermal transmittance for external walls:
U = 0,13 W m-2 K-1
Thermal transmittance for roof: U = 0,10 W m-2 K-1
Heat loss at project temp. -16oC Qloss = 5.370 W.
