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.
