Estimation of durability and stability of a 3-storey 2 spur frame-panel dwelling house by the action of the main load combinations.

Specialists STC "APM" by the order of "forest Belomorsky" was evaluated strength and stability of a 3-storey 2 spur frame-panel dwelling house by the action of the main load combinations. Place of construction: Arkhangelsk.

simulation design

Model building structure formed in accordance specifications. The main part of the building (walls and floors) is a wooden frame, the material of external and internal walls - pine.Cladding for external walls - stoneware tiles.

 
General view of the calculation model APM Structure 3D buildings
 
Truss roof system APM Structure 3D
 
The foundation of the building in the APM Structure 3D
 
Wall panels of the building APM Structure 3D
 
The elevated floor building APM Structure 3D
 
Socle overlapping buildings APM Structure 3D
Attic floor of the building in the APM Structure 3D

Load, impact and combinations thereof

load values ​​were set in accordance with the joint venture 20.13330 "Loads and effects." Uploading structure carried by several types of loads: regular (own weight of the structure, coating weight); useful (Distributed regulatory burden on the floor slabs); snow and wind, according to the construction area.

After all the loads on the individual loadings were created linear combinations of loads to which each of the loadings entered with respective coefficients. (Coupling coefficients, reliability coefficients for load, reliability coefficients for buildings)

 

The calculation results

 
equivalent stress distribution map of the building's roof truss system
 
Map of the distribution of total displacement in the roof truss system
 
Map equivalent stress distribution in the wall frame elements
 
Map equivalent stress distribution in the core frame elements
Map of the distribution of total displacement in the wall frame elements
 
Map equivalent stress distribution in basement ceiling elements
 
Map of the distribution of total displacement in the ground floor elements
 
Map equivalent stress distribution in the intermediate floor elements
 
Map of the distribution of total displacement in the elements between the floor slab
 
Map equivalent stress distribution in the attic floor elements
 
Map of the distribution of total displacement in the attic floor elements
 
Maps equivalent stress distribution in the ladder elements
