CFVR2859 - IS 800-07 test: Shear

Shear checking according to IS 800-07

A pinned-pinned steel beam is subjected to a surface load of 2.75 kN/m.
The beam has a length of 12 m. the cross section is a IPE 200.
The beam is made of Fe 430 steel which has a fy of 250000 kN/m².
The aim of the example is to obtain the cross section classification, and shear checking criterion according to IS 800-07.

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.
