Autodesk Robot Structural Analysis

[#1]

Can Robot determine the cracked moment of inertia( second moment of area) of a reinforced concrete section in particular a flat slab. Taking into account the reinforcement and tensile strength of the concrete

I appreciate that this would require several interations in order to produce the correct results.

Does it take into account tension stiffening?

Pease check the stiffness update method (http://forums.autodesk.com/t5/Autodesk-Robot-Structural/elastic-and-nonelastic-slab-deflection-verif...

The number of iterations is limited to one. The values of the reduction of stifness (inertia) are shown both as maps or in the reinforcement table.
