CFVR6101 - Poligonal pile wailing

Poligonal pile wailing design using Geotechnical Module utility

A pile wailing consisting of a rectangular slab and 4 piles subjected to a vertical force and placed in a lime soil terain.
Determine the total design of piles and slab considering it as rigid. (strut & tie method) according to EHE spanih code and axial force in piles.

Element types used in the model: BEAM4, SHELL43, LINK8

Needed CivilFEM Modules:
Geotechnical Module
Bridges and Civil Non Linearities Module
Advanced Prestressed Concrete Module

The example cannot be launched on an educational license.
