Alp 19.1

Alp analyses the soil structure interaction of a laterally loaded pile. The program represents the pile as a series of elastic beam elements and the soil as a series of independent springs. Maximum earth pressure coefficients may be specified to model soil shear failure. Alternatively non-linear soil behaviour can be modelled as p-y curves which are generated or specified. The program calculates deflection down the pile together with bending moments and shear forces within the pile.
