Tutorial 11 : STIFFNESS MODIFIERS FOR CRACKING OF STRUCTURAL ELEMENTS AND EFFICIENT INTERNAL ACTIONS

STIFFNESS MODIFIERS TO ACCOUNT FOR CRACKING OF STRUCTURAL ELEMENTS AND TO DEVELOP DESIRED EFFICIENT INTERNAL ACTIONS IN VARIOUS STRUCTURAL ELEMENTS OF RC STRUCTURES. STIFFNESS MODIFIERS AS PER ACI 318, IS 456, IS1893, IS16700 CODES IS EXPLAINED. IMPLEMENTATION IN ETABS IS DEMONSTRATED.

[@Aussie_Engineer]

Great explanation, sir please do one full high-rise building analysis and design.

[@sreejithsreekanth1369]

There is only one word for this video :- awesome.👍

[@yogeshshakya9558]

Such a good Tutorial Series Sir. Please upload more videos, it was a beautiful series.

[@dr.manmohanmaniyar6985]

Thank you, I will

[@azmat_waseem]

Very Informative... Thank you...

[@FahimKhan-xv4vb]

Thank you sir for useful explanation

[@dr.manmohanmaniyar6985]

Thanks

[@Darshit_7]

Thank you sir
for explaining in very simplified manner

[@dr.manmohanmaniyar6985]

Thanks, Darshit!

[@JaspreetSingh-dj3mk]

Easy explanation sir....

[@deep746]

Thank you so much, very will explained
Please make a video for transfer beam design in etabs

[@swastikpoojari7526]

Thank you sir for such a great explanation👍

[@dr.manmohanmaniyar6985]

Thanks.

[@FaizanShaikh-xd7bo]

can stiiffness modifer be give to torrsion in beam as 0.35 for strength model

[@fazalarju]

I request you to kindly make a video on design of shear wall and to find out reinf in boundary element. I will be very much grateful to you.

[@dr.manmohanmaniyar6985]

Sure!

[@vasubhadania]

I have a doubt
What will be the stiffness modifier for retaining wall...!?

[@Zorot99]

Sir can I apply the same factors using bs8110 design code?

[@aldiputra9236]

Sir, how we determine reinforcement in side rebar of raft foundation. Thank you

[@mansoorAli-pp9do]

Ty sir.
Qn: is it ok if i use scale factor of service model(eqx/specx) in ultimate model for analysis and design or i have to scale model in sls and uls both.
Qn 2: what will be the modifiers for spandrals?

[@dr.manmohanmaniyar6985]

Q1. Yes, scale up for both.
Q2. Spandrels are flexural elements like beams. Use appropriate modifiers numbers for beams for f11, f22 & f11.

[@dr.manmohanmaniyar6985]

First lecture will start on 11 September 2021.

[@azmat_waseem]

Sir, what about tutorial 10? not in the list???

[@fazalarju]

Sir, as I understood we can also use stiffness modifier as per IS 16700 2017 even for the bldg of height less than 50 m
Pl confirm yes or not sir

[@dr.manmohanmaniyar6985]

Yes, it is mentioned in the video..

[@ChinTanLimbani]

First thanks for the video sir....
in Column if Moment of Inertia is reduced for Bending only than why for Shear Wall it reduced for Axial (Membrane) direction? (As both are same type of load carrying system)

[@pulkitvelani]

Membrane is not axial. It is out of plane. And we want to design wall only to take load along length/inplane direction. Hence, 0.01 for mxx.
