Hi,
I am trying to model a voided slab using 2 models.
Model 1 - top flange, bottom flange and web modelled using plate elements. Height btw centroids of top and bottom flanges is 0.8m. Overall height is 1.0m. Model A1 is attached.
Model 2 - entire slab modelled using plate elements in the XZ plane. I work out that for the same load as Model 1, the uniform slab thickness is higher than 1m. How could this be? With a solid slab, the thickness should be less than 1.0m. Model A2 is attached.
Can you help?
