CFVR0926 - Shell shear reinforcement design according to Eurocode 2 (1991)

Shell shear reinforcement design according to Eurocode 2 (1991).

The model is made up of two square shell elements of 1.0m x 1.0m. The nodes of one side are completely restrained and one of the nodes between both element has its vertical movement restrained (perpendicular to the shells).
There is no initial shear reinforcement.
The applied loads is a pressure of 3 kg/cm² on one of the elements.

The reinforcement design code is the Eurocode 2 (1991).

Element types used in the model: SHELL43

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

The example can be launched on an educational license.
