Q

How must a ceiling be designed in structures in D, E, and F seismic design categories?

A

For structures in D, E, and F seismic design categories, the ceiling cannot be used to provide lateral support for partitions
Instead, partitions must be braced with vertical and diagonal wire bracing and a diagonal partition bracing that is independent of ceiling grid bracing

Q

How must a ceiling be designed in structures in C seismic design categories?

A

For structures in C seismic design category, partitions may attach to the ceiling grid IF the ceiling is braced to move laterally. This means the ceiling cannot be attached to the perimeter, but instead rigidly braced and clipped to the floor/roof above with a gap around the perimeter that provides the space to move laterally.

Q

4 installation terrazzo methods:

A
  1. Sand cushion = best way to avoid cracking since terrazzo is independent from structural slab
    Terrazzo tops a reinforced underbed with a layer of sand directly on the structural slab
  2. Monolithic = terrazzo is directly laid onto the structural slab. Needs control joints.
    Best used when floor thickness is an issue
  3. Bonded = use when floor movement or deflection is not expected
    Terrazzo tops an underbed that is bonded directly to the concrete slab
  4. Thinset = thin layer of terrazzo directly laid onto structural slab
    Best used when floor thickness is an issue

60
Q

What is the rotary method of cutting wood veneer?

Halved log and slicing slightly across annular growth rings

- Results in grain patterns somewhere between plain and quarter slicing
