CFVR0988 - Shell shear reinforcement check according to EHE

Shell shear reinforcement check according to the Spanish code EHE.

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 Forces & Moments are taken from external file CFVR0988.FM The reinforcement checking code is the Spanish code EHE. Longitudinal Reinforcement is defined: 863.938E-06 m2/m This example verifies D-02160, D-02162 (Class3 error)

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.
