CFVR4053 - Reinforced concrete design according to GB 50010 2010 Chinese code

Shear design without seismic action.

A concrete simply supported beam with rectangular shape section is subjected to a uniform load and two concentrated loads.
Determine the shear reinforcement according to GB 50010-2010.

Element types used in the model: BEAM3

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

The example can be launched on an educational license.
