    Hey, Hope you guys can help me out. I have a very simple concrete slab in a UBC seismic zone 4. The soil report is saying that there is no chance of liquefaction as ground water levels are lower than 60 feet. Do I still need to apply the seismic loading to the slab if this is the case and if...
