CFVR1426 - Concrete Pre-desing for rectangular sections

Predesign a reinforced concrete rectangular sections by parameters

The aim of this example is to obtain the reinforcement for different cross sections adapted to the existing loads. Parameters to bearing in mind:

Width.
Height.
Distance to the bottom reinforcement.
Distance to the top reinforcement.
Axil.
Moment.
Design calculus resistance of concrete.
Design calculus resistance of steel.
Type of section.

Element types used in the model: NONE

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

The example can be launched on an educational license.
