6m pile length and 1m diameter.
the required data :
1- ultimate shear force.
2- shear stiffness modulus.
3- normal stiffness modulus.
4- tip bearing capacity.
5- tip spring stiffness.
..... With thanks for your support.
Hi Ali,
Actually, there are some ways already presented in the MIDAS GTS NX manual, here is the link (Scroll down and click Pile http://manual.midasuser.com/en_common/GTS%20NX/100/GTS_NX/Mesh/Property,Coordinate,Function/Material/Material.htm). But the approaches presented do not give reasonable outputs, I've tried a case in some different software, and while others' results were similar, Midas gives lower responses in terms of structural load magnitude and different distributions.
You can calculate ultimate tip/base and shear/shaft resistance using conventional methods described in most soil mechanics text books - if you cannot do this should you be using this software? You can derive spring stiffness values using the method described e.g. by Fleming (1992) though you will need to linearise the curves.
Hi Ali,
you should analyze your soil profile in a conventional way and obtain these parameters in a "textbook way", like Peter Rutty already described. For stiffness, be careful and check how far away you are from geotechnical failure and adjust a secant modulus accordingly.
Hope this helps.
