    Concrete stiffness in slab design at Ultimate Limit State

    Thanks for yours comments. Using these reduction factors from AS3600 (who are by the way similar to those in ACI-318-19 cl. 6.6.3.1.1) affects the moments around transfert beams and edge column, way more than with my non-linear analysis. The relative stiffness between elements seems the most...

    Concrete stiffness in slab design at Ultimate Limit State

    While many standards tell to consider the effects of cracking, creep and shrinkage (e.g. CSA A23.3-14 cl.9.5.1 and cl.13.6.2) even at Ultimate Limit State , many designers simply run linear analysis using stiffness based on gross area to design concrete slabs. I did some tests on CSI SAFE and...
