Post-Tensioned Slab
One of the major design challenges when we design a Post-Tensioned transfer slab, is to consider the sequence of construction, so it’s required to stress the tendons in stages until reaching its final force. The question here, which approach is more reliable and can be considered in compatibility with the…
MESHING TECHNIQUES during Finite Element Analysis.
Hi Everyone, I would like to share my recent experience regarding the MESHING TECHNIQUES during Finite Element Analysis. 👉 In Pic 1, “Floor Meshing into 2 by 2” option is selected. This approach divided the floor into larger elements by creating 4 parts in each panel. 👉 In Pic 2,…
Why do we use diaphragm in ETABS
The main purpose of using diaphragm is to transfer the lateral load to the system. This will only be used when you are having slabs but when your model doesn’t have slab then the lateral forces needs to be applied at the joint Slab possess very high resistance to lateral…
