Voided Biaxial Slabs - what are the problems encountered during design, detailing and implementation


Can it be a lower tech alternative to Post Tensioned Slabs?

  1. Do you mean by voided biaxial slabs, the hollow blocks and sphere slabs?

    If so, then in my openion yes it is a lower tech alternative to post-tensioned slabs, however that low tech system requires beams to support the ribs. In post-tension, no beams are required and it looks just like the flat slabs from bottom. Moreover, thickness of hollow blocks or hollow sphere starts from 200mm as far as I remember. So you can't propose that system by all means in a tower! Unlike the post-tensioned slabs will give you large spans with viable thicknesses allowing you to add floors from the reduced heights!

    I hope this answered your question 🙂
