Cracked moment of inertia concrete
WebOct 17, 2024 · Cracked condition for reinforced concrete columns. Question: Hello. I have a question about how midas determines for structural analysis what moment of inertia to use for beams and columns. Given that either the cracked or uncracked condition might be used, I am unsure what the program defaults to, and how to change from one … WebMethod 2 : Specifying the cracked section properties through Property Reduction Factors . From STAAD.Pro 2007 onwards, STAAD has an option to define reduction factors for member properties like cross sectional area and moment of inertia. These reduction factors can be specified from the General - Specs - Beam page of the program, as shown next
