Pdisp (formerly Vdisp)

Pdisp calculates the displacements (and stresses if required) within a linear elastic or non-linear soil mass, arising from uniform normal or tangential pressure, applied to rectangular and circular loaded planes.

The program is ideal for predicting the displacements that may arise due to the action of several loads in a soil mass, and gives the user an understanding of the settlement pattern likely to arise both beneath and beyond the loaded area being analysed.

The program assumes the soil is an elastic half-space when calculating the stress changes within the soil. Individual layer properties are used to calculate the vertical strain and the displacements resulting from these stresses. It effectively replaces the need for the engineer to use Newmark charts and other similar devices.

Pdisp is a development of (and replacement for) Vdisp. Vdisp predicted displacements induced by vertical loads on horizontal loaded areas only. Pdisp is capable of predicting displacements due to both vertical and horizontal loads.

Key Benefits:

• 3D graphical output view, which improves the representation of the displacement profiles for the input and output
• Easy access to input data, tabular data and graphical views with the gateway window
• Analysis of soil-structure interaction with raft structures (e.g. basement slabs), through Pdisp and GSA link

Key Product Features:

• Loaded areas can be superimposed and can be specified to act at different levels
• Loads can be normal and tangential as well, and can act on both hoizontal and vertical planes.
• A number of horizontal soil layers may be specified; the base of the bottom layer is assumed to be rigid
• A linear variation of modulus with level may be specified for each soil layer
• Displacements and stresses may be specified for any soil layer
• Analysis based on the equations of either Boussinesq or Mindlin
