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.
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.
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
