research of the is intense-deformed condition of a settlement model of a dome.

Static calculation of a model of a dome spent by means of a program complex Lyre 9.4. Settlement schemes, schemes zagruzheny and results of calculation, are given on fig. 4.

Fig.

4.22. To calculation of rods and knots of a model of a dome and number numbering

Standard sizes on a dome of elements and knots.

The analysis of settlement schemes and loadings, and also distribution of efforts in schemes (and - with an eccentricity without string pieces, - with string pieces and without an eccentricity 4.24) shows fig., that settlement efforts and the maximum pressure in racks differ no more, than on 15 %, string pieces complicate knots and make heavier a dome.

And

Fig. 4.23. To calculation ogolovka and bases of a rack: and - basic knot of a dome; - a pressure distribution at a basic slab.

Therefore we will select for the experimental check, less studied

Variant on racks with an eccentricity.

Fig. 4.24. A mosaic of axial forces: and - for symmetric zagruzhenija 8000 N on on 6 central knots of the panel of a dome without string pieces; - for symmetric zagruzhenija 8000 N on knot with string pieces on a contour.
