Design of shear walls for Moment Envelop?
abbaskhan2294 and one other reacted to Badar (BAZ) for a topic
Concept of envelope is to find maximum value of design force (shear, moment, torsion) or displacement for a bunch of loading scenarios at various locations along the member. Influence line is different. It gives you the value of force/displacement for a single point on a member for various positions of same loading type. Of course you can create envelope in this case as well.2 points -
Design of shear walls for Moment Envelop?

Like Baz said, envelopes would summarize the max, but they may lead to very conservative design. CSI itself suggests not using envelopes. Ref: https://wiki.csiamerica.com/display/etabs/Envelope+combination+not+for+design1 point -
ETABS: Thin Shell Vs Membrane
UmarMakhzumi reacted to Badar (BAZ) for a topic
If the shell element has been designated as being membrane (in-plane behavior) , ETABS will not transfer out-of-plane loads.1 point -
Steel Material testing number
UmarMakhzumi reacted to Simple Structures for a topic
1. Material properties from Manufacturer/Supplier of steelwork section, i.e Steel Mill. This information is trusted in the West (however, in South Asia, just double check that the certificate is genuine) 2. Welding and connections verification /certification by Fabricator or the testing Company he has used, if independent checks are done.1 point
