What is Slab Design and Estimation Guide about?

Here are the key steps to check the minimum slab thickness using the Direct Design Method: 1. Calculate the beam moment of inertia Ib based on the effective beam section. For the 12 in. wide beam, Ib = 144 in4 2. Calculate the slab moment of inertia Islab = bh3/12 = 7(12)3/12 = 504 in4 3. Calculate the beam-to-slab stiffness ratio a = Ib/Islab = 144/504 = 0.286 4. Use a = 0.286 to determine the minimum thickness from Table 9.5(c) for fy = 60 ksi, no edge beams. The minimum is 6.5 in.
