The side force that the firm sheet 4 of level self produces in the step described above (4) is calculated by the weight ratio that the firm sheet 4 of level accounts for firm sheet 4 particles of place level.
In the step described above (4), the side force that the firm sheet 4 of adjacent level transmits is edge strut 7 or the film internal overarm support 6 that the firm sheet 4 of adjacent level passes to side force by edge strut 7 the firm sheet 4 of level.
The computing method of the side force that the firm sheet 4 of institute's support level that vertical sheet 3 is just born in the step described above (5) produces are: 1. the side force mean allocation of the firm sheet 4 of level in the firm sheet element of the freely-supported unit is given vertical sheet 3 just; 2. the side force mean allocation of freely-supported section 4-1 of the firm sheet 4 of level in the firm sheet element unit of encorbelmenting is given vertical sheet 3 just, and the side force of the section of the encorbelmenting 4-2 of the firm sheet 4 of level is distributed to contiguous vertical sheet 3 just; 3. reverse whole side forces of the firm sheet 4 of level in the firm sheet element unit and distribute to contiguous vertical sheet 3 just; When 4. the vertical firm sheet 3 in upper strata was seated on the firm sheet 4 of lower floor's level, the level interval that supports 3 of vertical firm sheets by the vertical sheet 3 just in upper strata and the firm sheet 4 of lower floor's level was weighted distribution; When 5. the firm sheet 4 of level passed to the firm sheet 4 of adjacent level with horizontal loading, the level interval that supports 3 of vertical sheets just by film internal overarm support 6 and the firm sheet 4 of load-bearing level was weighted distribution.
