Embedded pile row lateral resistance

Question

For the embedded pile row, what does the lateral resistance represent? Is it the same as the passive resistance behind laterally load piles or is it the p-y curves? Is there a reference that provides information on how to model the multi-linear resistance? Thank you

Dear Benan, 
 The lateral resistance is explained in detail in our Reference manual. 
 In short, this allows for limiting the transverse forces that can happen due to lateral displacements. The multi-linear resistance is merely a table that can be defined by users that will allow taking into account inhomogeneous or multiple soil layers with different properties.
