Software →Ensoft Group 2022.12.6

The program generates internally the nonlinear response of the soil, in the form of t-z and Q-w curves for axial loading, in the form of p-y curves for lateral loading and in the form of T-q curves for torsional loading. A solution requires iteration to accommodate the nonlinear response of each pile in the group model. Program GROUP solves the nonlinear response of each pile under combined loadings and assures compatibility of deformations and equilibrium of forces between the applied external loads and the reactions of each pile head.
Pile Sections
User defined piles with circular, rectangular, and/or wide-flange sections, with option to include nonlinear flexural stiffness for standard reinforced concrete sections for complex composite sections with structural steel inserts.
Elastic
Circular (hollow or full)
Rectangular
Custom widge flange
Predefined AISC sections from built-in library
User defined sectional properties
Nonlinear
Circular section with or without rebar reinforcements
Circular sections with casing
Circular steel tubes
Predefined AISC sections from built-in library
Prestressed square sections
Presstressed octagonal sections
User defined EI
Loading
Accepts combined loadings (axial + lateral) with load factors and with ability to compute maximum and minimum envelops for load cases and load combinations.
Users may specify concentrated loads (at any position) at the pile cap and/or distributed lateral loads (using local or global axes) along the length of any pile(s).
Includes option to use cyclic model for soil p-y curves where available.
Soil Movement
The user is able to input a profile of soil movements versus depth as additional loading on the pile. The movements of the soil may be produced from any action that causes soil movements, such as those due to slope instability, lateral spreading during earthquakes, and seepage forces.
