If the load, warping and frictional stresses in a cement concrete slab...
Critical combination of stresses:
(i) During Summer mid-day at bottom of slab (Load stress + warpings tress - friction stress), at edge region = 210 + 290 - 10 = 490 N/mm2
(ii) During winter mid -day at bottom of slab
(Load stress + warping stress + friction stress); at edge region = 210 + 290 + 10 = 510N/mm2
(iii) At top Of slab during midnights
(Load stress + warping stress), at corner region.
(i) During Summer mid-day at bottom of slab (Load stress + warpings tress - friction stress), at edge region = 210 + 290 - 10 = 490 N/mm2
(ii) During winter mid -day at bottom of slab
(Load stress + warping stress + friction stress); at edge region = 210 + 290 + 10 = 510N/mm2
(iii) At top Of slab during midnights
(Load stress + warping stress), at corner region.

If the load, warping and frictional stresses in a cement concrete slab...
Given data:
Load stress = 210 N/mm2
Warping stress = 290 N/mm2
Frictional stress = 10 N/mm2
To find: The critical combination of stresses during summer midday.
Solution:
The critical combination of stresses during summer midday occurs when all the three stresses act together. Therefore, the total stress can be calculated by adding all the three stresses.
Total stress = Load stress + Warping stress + Frictional stress
Total stress = 210 + 290 + 10
Total stress = 510 N/mm2
However, as per the principle of superposition, the maximum stress will occur at the time when the load stress is maximum. Therefore, during summer midday, the load stress will be maximum.
Therefore, the critical combination of stresses during summer midday will be:
Total stress = Load stress + Warping stress + Frictional stress
Total stress = 290 + 210 + 10
Total stress = 510 N/mm2
Hence, the correct answer is option C) 490 N/mm2.
Load stress = 210 N/mm2
Warping stress = 290 N/mm2
Frictional stress = 10 N/mm2
To find: The critical combination of stresses during summer midday.
Solution:
The critical combination of stresses during summer midday occurs when all the three stresses act together. Therefore, the total stress can be calculated by adding all the three stresses.
Total stress = Load stress + Warping stress + Frictional stress
Total stress = 210 + 290 + 10
Total stress = 510 N/mm2
However, as per the principle of superposition, the maximum stress will occur at the time when the load stress is maximum. Therefore, during summer midday, the load stress will be maximum.
Therefore, the critical combination of stresses during summer midday will be:
Total stress = Load stress + Warping stress + Frictional stress
Total stress = 290 + 210 + 10
Total stress = 510 N/mm2
Hence, the correct answer is option C) 490 N/mm2.
