For a reinforced concrete shear wall , is the minimum wall thickness equal to :

a) unsupported height / 25 b) unsupported length 25 C) 0.8* unsupported length d) the smaller of (a ) and (b)

2. What recommedations do you recommend if the shear in a two -way flat plate is not safe ?

3. Is the effective depth in two -way flat plate the same in both directions ? If yes , why and which direction you start the design with ? If no , why and which direction has more effective depth
