Pile Raft Modelling?
Abdirahman Yasin
Dear all, When modelling pile raft in plaxis 3D such that the piles will carry around 70% of the load. Do we need to use interface elements to capture this effect or by modelling pile + raft + soil materials, this effect will already be captured?…

RE: Volume elements
Stefanos Papavasileiou
Dear Abdirahman, The activation of the material of piles in a phase simulates the case of a whished-in-place pile. This means that the soil is instantly replaced by the concrete (or any material) of the pile. The calculation will consider the strength…

RE: HS small parameters.
Stefanos Papavasileiou
Dear Abdirahman, The Gmax = G0ref and indeed it can be obtained by as you mentioned by geophysics tests (measuring the shear wave velocity Vs). There are different correlations for γ0.7 published online along with some suggested values. Of course…

RE: Dummy plate properties in PLAXIS 3D.
Stefanos Papavasileiou
Dear Abdirahman, In principle, you can pick any factor to reduce the parameters, which you need to keep in mind when checking the results in Output. We suggest picking a factor of 1E4 or smaller. Apart from the zero unit weight, please keep in mind…

RE: the function of Add tunnel phase routine
Stefanos Papavasileiou
Dear Abdirahman, We still need to implement this for PLAXIS 3D. I have added your request to my report to our developers.

RE: Displacements obtained from pseudostatic slope analysis?
Stefanos Papavasileiou
Dear Abdirahman, Force-based pseudo-static methods (as the one implemented into PLAXIS) represents the effect of complex, transient, dynamic effects of earthquake shaking by constants inertial forces, which are incrementally applied to the whole mesh…

RE: Seismic Earth pressures
Stefanos Papavasileiou
Dear Abdirahman, The results obtained in Output are not separating the components of the stresses depending on the type of analysis. The σxx are the total horizontal stresses for that calculation phase. Providing that changes in geometry, materials…
