h. ITA/EIA Standards
2. Loads (Dead, Live, Snow and Wind)
a. Seismic is not considered since for a slab on ground (without piles), the slab will move with the ground and there is not a structure period associated with it (different from pile-supported slab). b. However, seismic shear may need to be considered for the grade beams; further work required to confirm.
c. Load combinations (per Table 5.3.1 of ACI 318-14)
III. Environmental Conditions
