Its free without saving for non commercial, can help you a lot. Follow this link: Look for fine geo software.I really liked Finland.īack to your question, I think it is enough to calculate settlement.Įquation : soil layer * soil layer thickness / modulus of soil layer (equation explained in links below) Well hello, I actually spent some time Aalto uni studying structural eng. This is what you deal with in double parametric model (winkler pasternak) It considers shear capacity of soil aswell: There are many different approaches how to reproduce soil with springs (single parametric model, double parametric model.) To calculate springs it is an iterative process with defined margin of error.My approach is to use soilin to approximate springs and if i want to make calculation faster then I use linear area springs calculated by soilin.Use wisely with caution (know what you are doing) cause it can yield wrong results One example is building with elevator core - core will take more load and thus the contact pressure on foundation slab will concentrate under core and that yields different deformation zone depth and different spring constant than 10m away from core.If your load changes your springs changes aswell.If foundation is large area with bending (not 100% stiff) then your springs will vary accordingly.If your foundation is stiff and small > your spring will be constant for whole foundation.RF soilin does the calculation for each finite element individually thus you get exact spring for each element of your mesh.if Deformation zone depth changes - spring changes aswell (all changes with load change).If you know that you can continue and calculate springs. From that you know which soil layers apply for bearing capacity then you can evaluate settlement. Defomration zone depth is important factor.

In general: You need to know weight of the structure and setlemment.

Spring = Force / Settlement įorce - settlement is not a LINEAR dependance! Shall be given without reservation for the public good.Īnd in fidelity to my profession, I shall give the utmost. Practical use the principles of science and Has been spurred by the engineering genius.
