Strength calculation of a 3-storey frame-panel residential building
(Astrakhan region)

3-storey frame-panel

Specialists of STC "APM" was assessed the strength and stability of the wooden 3-storey frame-panel residential building under the action of the basic load combinations. The construction site of the Astrakhan region.

  

simulation design

     The estimated model home designed according the data provided by the customer and was modeled using rod and shell finite elements. The main part of the building (walls and floors) are a wooden frame (glulam) with cavities filled with non-combustible mineral board. Frame from the outside and inside of it is sheathed cement particle board (DSP) of different thickness. Instead, the DSP can use object-strand board (OSB). House foundation tape precast concrete.

The computational model of frame-panel house in APMStructure3D
Truss system in the roof of the house APMStructure3D
Reinforced concrete frame house in the basement APMStructure3D
Wall panels and wooden frame of one floor of the house in APMStructure3D
Intermediate floor on the basis of wooden frame houses
Concrete slab basement ceiling panel houses

load:

     load values ​​were set in accordance with the SP 20.13330.2011 "Loads and effects."

     Uploading the house is divided into several types:

constants loads - own weight of frame houses, stiffening diaphragms, insulation and sheathing weight (cement particle board);

-Useful load - time evenly distributed load on the slabs of people and equipment (for premises 150 kg / m 2 , for balconies 400 kg / m 2 , for corridors and stairs 300 kg / m 2 , for attic 70 kg / m );

- snow load - the construction site belongs to the II Snow district. This load is applied to the roof, made of corrugated sheet;

- wind load - the construction site belongs to the V wind areas. This load is exerted on the wall panels, gables and roof of the roof.

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

The calculation results

Map equivalent stress distribution in the wooden rafters and gables of the building roof
Map of the distribution of total displacement in the wooden rafters and roof gables
Equivalent stress distribution map of wooden frame elements of the first floor
Map equivalent stress distribution in the intermediate floor of wooden elements
Map of the distribution of total displacement in wooden elements of floor slabs
Map of equivalent stress distribution in wooden elements of attic floor
Map of the distribution of total displacement in wooden elements of attic floor
Map of distribution of the vertical load on the reinforced concrete foundation
distribution map of the bending moments about the axis X in the concrete slab
Map of distribution of bending moments around the Y axis in the concrete slab
vertical displacement distribution map uzB concrete slab
The results of the verification calculation of reinforcement overlap zhelezobetonnoyplity

     Analysis results of the calculation shows that under the given design loads, the frame-panel house has the necessary margin of strength and stability for normal use. In this case, all applied loads are able to carry a wooden frame house, excluding the extra rigidity and stability which gives the house wall cladding made of cement particle board.
