Easy input of p-y curve parameters for various soil and rock materials

 

Various p-y curve parameters for soil and rock materials can be easily input by the users. The program will automatically determine the parameters based on the material type and strength. Advanced options are also available to the users who want to have more control over p-y curves. In total, 14 p-y curve models for various soil and rock materials are available in PileLAT for the users to choose.

A simple way to access and view all the analysis results on one window dialog

​

All analysis results such as deflection, shear force, bending moment and soil reaction can be accessed from one window dialog. The users can easily switch between different result plots. 

​

 

P-y curves for any node point along the pile can be easily displayed with a simple click

 

Nonlinear p-y curves for any node point along the pile length can be displayed and copied once the analysis is successfully completed.

Various loading conditions including specified horizontal displacement or rotation can be applied to the pile head

 

The vertical force also can be applied to the pile head and P-Delta effects can be analyzed by the program.   

 

Complete Feature List

  • Automatic generation of nonlinear p-y curves for various soil and rock materials such as cohesive soils, cohesionless soils, and rocks; 

 

  • Both static and cyclic loading behavior including P-Delta effects when axial loading is applied to the pile head; 

 

  • Pile batter and sloping ground surface can be modeled through an interactive dialogue where the geometry of the pile batter and ground surface slope can be graphically updated and viewed by the user with moving the relevant slide bars; 

 

  • P-multipliers can be defined by the user for each soil layer to consider the potential pile group effects for closely-spaced piles; 

 

  • Multiple pile segments with different user-defined elastic bending stiffness or Plastic Bending Moments can be specified by the user; 

 

  • Free-field soil lateral displacement loading along the pile length can be considered by the program at the specified node locations. The adopted analysis approach in PileLAT is based on the publication entitled "Response of Piles d Casings to Horizontal Free-field Soil Displacements" by Byrne et al (1984); 

 

  • Distributed horizontal shear forces and bending moments can be specified by the user at any node positions; 

 

  • Boundary conditions at the pile head such as free head, rigid head and partially restrained head with elastic rotational spring can be considered; 

 

  • Different pile section types such as circular section, rectangular section, steel H-section, steel pipe section, octagonal section and user-defined section can be selected by the users; 

 

  • Straightforward soil Layer and Parameter Input Dialog is provided to help the user to enter the input data more easily and smoothly; 

 

  • A well-designed Result Output Dialog is provided for the user to view all the relevant results graphically. Switching among different results is very straightforward. 

 

  • Standard window-style dialogs, push buttons, drop menus, list boxes, EXCEL-like data grid  cells, slide bars, radio buttons, check boxes and toolbars can be accessed in the program
