CFVR2854 - IS 800-07 test: Tension

Tension check according to IS 800-07

A simple beam is subjected to a tension load of 600 KN.
The bars have a length of 1 m.
The cross section is an Angular L 120 x 120 x 12.
The bars are made of Fe 410 steel which have a fy of 250000 kN/m².
The aim of the example is to obtain the cross section classification, the tension criterion according to IS 800-07.

Element types used in the model: LINK1

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

The example can be launched on an educational license.
