DATA PROCESSING AND CALCULATIONS

• The recorded horizontal accelerations and LVDT readings will be processed and the lumped mass model will be used to simulate the horizontal soil layers.

• Calculations:

  Uj = horizontal displacement of node j (j= 0,N)
  
  hj = thickness of the jth layer (j= 1,N)
  ? j = mass density of the jth layer (j= 1,N)
  mj = mass per area on the jth node, defined by the following equations:
