CFVR0925 - Shell shear reinforcement check according to Eurocode 2 (1991)

Shell shear reinforcement check 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).
The shear reinforcement are 12 mm bars each 14 cm in both directions.
The applied loads is a pressure of 3 kg/cm2 on one of the elements.

The reinforcement checking 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.
