10 Brace (truss) 1 Story Building

11 Slab = “Diaphragm” Brace prevents X-direction Movement of this point

12 Slab = “Diaphragm” Brace prevents X-direction Movement of this point
Y-direction Movement of this point

13 Slab = “Diaphragm” Brace prevents X-direction Movement of this point
Y-direction Movement of this point Slab is rigid in X-Y Plane. Slab is connected to every other point

14 Slab = “Diaphragm” Braced Braced Braced Braced Braced Braced Braced
Slab is rigid in X-Y Plane. Slab is connected to every other point. Therefore: Slab + braced points = Every column is braced. Braced

15 Slab = Diaphragm: a body that with planar rigidity
Slab = Diaphragm: a body that with planar rigidity. With several braces and a floor diaphragm, all columns are braced Braced Braced Braced Braced Braced Braced Braced Braced Braced Braced Braced Braced Braced Braced Braced Slab is rigid in X-Y Plane. Slab is connected to every other point. Therefore: Slab + braced points = Every column is braced. Braced
