Analysis Using the Compression Constant
The equation to compute compression of an ith soil layer below foundation having a thickness h arises from the definition of compression constant C:
vertical component of original geostatic stress in the middle of ith layer
vertical component of incremental stress (e.g. stress due to structure surcharge) inducing layer compression
thickness of the ith layer
compression constant in the ith layer
The program allows for inputting either the compression constant Ci or the compression constant C10 (the program itself carries out the transformation).
