Dear experts
I have building 84m x 84m flat slab without expansion joint and according to the specification of the client reviewer I have to put the temperature in both cases negative (-15) and positive (+25), and in case of negative temp. I used cracked section (area modifier =0.4)and in case of positive temp. I used uncracked section (area modifier= 1),the positive case made a beg straining action on the shear wall because the section of the wall is uncracked and made restrain to the slab but when I put it cracked the straining action is reduced.
