Bearing Capacity Software (PEYSANJ)

PEYSANJ is a unique software designed for bearing capacity and settlement analysis, earth pressure calculation, plate load test and pressure-meter test processing.

SKU: NV08 Category:

The only software for parallel analysis of soil shear failure and foundation settlement for bearing capacity analysis!


PEYSANJ geotechnical software covers a wide range of day-to-day engineering analyses. includes the following analysis modules:

  • Bearing capacity and settlement analysis
  • Detailed stress distribution analysis due to:
    • surcharge load behind retaining walls
    • footing pressure (crane pads, wall, pad footing, etc)
  • Earth lateral pressure coefficients
  • Plate Loading Test (PLT) data processing
  • Pressure-Meter Test (PMT) analysis

Bearing Capacity Analysis


PEYSANJ is the only software you need for your bearing capacity analyses! Many jobs are too complicated for a simple Excel spreadsheet calculation and need more sophisticated analyses for multi-layer stratigraphy, water level effects, and so on. Here are some of the features provided by PEYSANJ:

Allowable bearing capacity should meet both shear failure and settlement criteria. PEYSANJ uses “Hansen” method for analysis of soil shear failure by considering the effect of groundwater table in bearing capacity analysis. For settlement analysis, “Steinbrenner and Goodier (Timoshenko)” and rigid foundation formulas are used. Both immediate (elastic) settlement and one-dimensional “Terzaghi” consolidation formula are estimated for settlement analyses.

Total settlement of the footing is then calculated by summing up the elastic and consolidation settlements. For each footing size, the minimum values of allowable stresses for shear failure and settlement criteria are compared and the introduced as the “Allowable Bearing Capacity” of the footing.

Calculation details
Excel output
The details of all bearing capacity and settlement calculations are presented in a table. In addition, the results can be exported in Excel file for edit and further presentation purposes.

Processing Menard pressure meter test is easy using PEYSANJ! The analysis is based on ASTM D4719 and input data consist of calibration data, pressure (P) and volume (V) readings, groundwater level, etc.

After computing the elastic portion of the P-V curve, “Menard Modulus (Em)” and “Limit Pressure (Pl)” are reported. Pressure vs volume is also plotted along with elastic and plastic phases of the test. The elastic phase of the loading curve can be edited by the user in order to choose the most reasonable set of Em and Pl.

Static Ka, Kp and Ko

Calculating the active, passive and at-rest lateral earth pressure coefficients based on both Rankin and Coulomb methods. The latter considers the effect of soil-wall friction, backslope, and wall batter angle. The magnitude of the resultant force and its point of application is calculated.

Seismic Kae and Kpe
Lateral earth pressure coefficients for earthquake condition are calculated according to Mononobe-Okabe method for different horizontal and vertical components of the ground acceleration. Detailed values of Kae and Kpe are calculated for every 0.05g steps of av and ah. In addition to earth pressure coefficients, the seismic surcharge load (Pae-Pa) and total seismic force (Pae) behind the retaining wall are presented.

This test is widely used to determine soil elasticity modulus (Es) and modulus of subgrade reaction (Ks). Input data consists of the load (P) applied on the plate, and settlement (S) measured from the gauges. Then PEYSANJ automatically splits different loading-unloading cycles and calculate Ks values for each cycle. Stress-Settlement diagram is also plotted and average Ks value calculated. Another module for converting Ks30 to Ks of the footing is available in this module.

  • Automatically detecting loading / unloading cycles
  • Calculation details for each loading cycle including modulus of subgrade reaction
  • All input data and formula are inserted in final report
  • User can manually determine the elastic phase if necessary
