WEBINAR: Application of Auto Lateral Wind Loading in ETABS

This webinar discusses the auto lateral load feature in ETABS. Examples will include load application from diaphragms, shells and open-structure loading onto frames.
This video is a recording of the webinar that took place on June 25, 2019.

Thank you for this webinar, kindly upload the video with better resolution and quality

how can i apply auto wind load on an open framed structure such as a steel bridge made of truss or a transmission tower etc.

[@BoydRocks]

Would it be possible to publish all the Questions and Answers that were not addressed during the video? It was implied that they would be answered and I assume provided to the attendees.

Does ETABS consider the (internal pressure coefficient ) upon the classifcation of enclosure??

[@94Tyberius]

Was wondering about this myself as using 0.18 vs 0.55 vs 0.00 can make a big difference.

[@94Tyberius]

After watching a bit more of the video, it looks like it uses the simplified procedure (Section 27.4) which automatically assumes an enclosed structure (0.18 for GCpi). As a follow up question now, is there a way to change this or would you need to manually input the wind pressure coef's to account for a partially enclosed structure? Or is it recommended to simply not use the auto-wind load feature when dealing with partially enclosed or open structures?

If I want to apply wind load to the roof and sides, I can't use diaphram method. Am I right?

[@emanretsiger9343]

To apply wind load on the roof and sides at the same time, diaphragm method can't be used. In such cases the wind load on the roof should be applied manually in a separate load case and can be combined in a 'Load combination' as one.

The maximum absolute changes in the El and EA reduction factors is 0.2. For 912 members, the reduction factors decreased by more than the negative tolerance of 0.01. Do you want to reiterate analysis and design?
Can you Explain what does it meam please ?

Hello sir...how to apply Tuned liquid dumper in Etabs softwar....plz

So when should we select a rigid diaphragm, and when should we select a semi-rigid diaphragm?

[@nicolasramirez3944]

Rigid when you can neglect all in-plane stress and deformation. All joints of a rigid diaphragm are constrained to equal deflection, therefore there are no stresses. See ASCE7 for diaphragm categories.

[@wahidrahmatzada5495]

I couldn't find a way to select and delete diaphragm if I need to.

Select the floor go to assign
Shell
Diaphrahm
Select none
Apply
Ok

How can a play minimum wind loading 0.77kn/m2 as ASCE 7-10

[@zubair4137]

Sir can you please share this AutoCAD file i want to practice this plz

[@ibaha411]

CSI should remove this webinar and redo it lol this doesn't seem to teach at a level that other CSI videos do!!! I know how ETABs does wind analysis generally. I watched this video for 44 mins and I learned not much! Is there any other wind analysis tutorials or webinars? And the presenter doesn't even know what windward and leeward mean!!!
