Buenos días, porque razón me sale vacío en la tabla de "Story Stiffness", etabs versión 20?, gracias.

[@EngineeringLearningPlatform]

You need to click on calculate story rigidity on run window

Dear Sir, Thank you for the video. I have a question; how can I calculate STIFFNESS in X-DIRECTION manually for a simple 2D steel building frame?

[@EngineeringLearningPlatform]

Stiffness is the force required to produce unit deformation. Calculate force required simply for 1inch deflection simply as it's kip/in.

[@TinTin-fv4qc]

What could be a possible reason if etabs table does not show result for story stiffness for response spectrum?

[@sapkotaashish]

Thanks for the tutorial. From which link (not that in the description --PDF is of no use.) can we download the excel file?

[@EngineeringLearningPlatform]

yes see link in description it's on stuvia website . Many have downloaded previously

[@sapkotaashish]

I am confused. We can only download the PDF (free) not the excel. So, that means the Excel file can be downloaded only when payment is made and not for free?

[@EngineeringLearningPlatform]

@@sapkotaashish yes .

[@EngineeringLearningPlatform]

But soon there will be membership option available so that all sheets will be free once you are a member, i am working on it

DO YOU HAVE CALCULATION NOTES IN EXCEL SHEET FOR FOOTING,BEAM,COLUMN & SLAB.??

[@EngineeringLearningPlatform]

Yes not for column as yet . You can browse through etabs playlist and see slab, beam, footing design videos

@@EngineeringLearningPlatform THANK YOU SIR.CAN I GET YOUR WHATS APP NUMBER OR EMAIL..?

[@salimrafeeq3090]

If we checking for response spectrum in X Direction (spec X) and the values in y direction comes zero what it means ? The analysis is performed for monolithic building system completely made of shear walls.

[@EngineeringLearningPlatform]

And static base shear is non zero?

Sir i didnot found the the stifnes table in etabs, infact i chexk before showing me no warning massag

[@suhaibkhan7356]

Can you please tell in which clause IS CODE stiffness should not less 70 or 80 percent,,

[@EngineeringLearningPlatform]

ACI code chapter 10

[@kkb3091]

Should we check it using cracked section properties?

[@EngineeringLearningPlatform]

Yes

[@kkb3091]

@@EngineeringLearningPlatform sometimes code instructs to use modifiers=1.43x cracked section modifiers(I=0.7 for column, 0.35 for beam and 0.25 for slab) for serviceability conditions like lateral displacement. So, I was confused whether to use cracked section properties or 1.43 times the cracked section properties.

[@EngineeringLearningPlatform]

@@kkb3091 Don't be confused, keep things simple . Say you need to find abeam's deflection you used the "Ie" effective moment of inertia but that involded tedious calculations, so on global structural scale, the code recommended values for considering a cracked concrete effect into all serviceability checks no matter you name it gravity or lateral . U can use the code recommended by ACI as far as it's non-prestressed concrete

[@kkb3091]

@@EngineeringLearningPlatform Thanks a lot!!!! Now I think I am clear about it. 🙂

[@ahmedmelmeniawy3408]

If not OK how to fix that proplem?

[@EngineeringLearningPlatform]

Its not a problem, but just a characteristic of Structure . In 99% cases unavoidable due to architectural purposes . So you got to apply Structural design procedure for this irregularity .

[@Shahab087]

Sir i didnot found storey stifness table, it missing in my wind tab

[@EngineeringLearningPlatform]

Then you haven't applied wind loads

there is no excel sheet to download it,
