Bearing Capacity & Settlement 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. Allowable bearing capacity should meet both shear failure and settlement criteria.

PEYSANJ uses “Hansen (modified Terzaghi)” method for analysis of soil shear failure (including the effect of groundwater table, if present). For settlement analysis, “Steinbrenner and Goodier (Timoshenko)” and rigid foundation settlement equations are used. Both immediate (elastic) settlement and one-dimensional “Terzaghi” consolidation settlement will be estimated for settlement analysis.

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 it is selected as the “Allowable Bearing Capacity” of the footing.

Calculation Methods

Every little details in calculation of bearing capacity and settlement matters!

We know that soil mechanics is a complicated science, and PEYSANJ is designed to give you the power of choosing the calculation methods.

In addition, for each type of analysis, calculation details and a formal report are provided.

Plate Loading Test

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 on the gauges. PEYSANJ automatically detects different loading-unloading cycles, and it calculates Ks values for each cycle. Stress-Settlement diagram is also plotted and average Ks value is calculated. Another feature in this module is conversion of Ks30 to Ks of the footing.

  • 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

Menard Pressure-Meter Test

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.

Lateral Earth Pressure

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 also 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 vertical and horizontal ground accelerations. In addition to earth pressure coefficients, the seismic surcharge load (Pae – Pa) and total seismic force (Pae) behind the retaining wall are presented.

Simplified Slope Analysis

Using this page user can roughly estimate the stable slope based on the design chart proposed by Fang et al. This chart is prepared based on a series of limit equilibrium analyses, and should be only used as a rough estimate since it does not take many parameters such as groundwater level, surcharge, etc. into consideration.
