Base-Load Proportion for Incompressible Pile BETAo
The base-load proportion for incompressible pile β0 represents the influence of compression of elastic half-space, which adopts the load transferred by the pile from incompressible soil. The values of this coefficient are generally presented as a function of the pile length to pile diameter ratio (l/d) for various pile base diameter to pile diameter ratios (db/d). These graphs are implemented in the program in a digital format.
