You are really explaining very well. It made me so clear and understand R

[@nikeshrathod7698]

Indeed Fantastic Explanation about R. Really Thanks....

[@civilengineeringwitharas4776]

Thank you very much for such explanation, My question is here: If a structure is designed based on (R & Omega), then the structure will not resist a seismic force equal to V_elastic, because we will not reach point A through path OBC. Does this mean the structure is under design?

[@HninHninHlaing-wg7tu]

Thank you so much for your very clear explanation.

[@ManiKandan-nh7kz]

Thank you so much brother
Good explanation and I understood why we use R value in seismic design

[@UnderstandingStructures]

Thank you 🙏

[@gowthams-s5b]

As in general Spectrum is taken from Single degree of freedom systems, is the R also not to account to convert from SDF to other systems?

[@venkatesh2285]

You are teaching asce code or indian code? Because you used unit kN in explanation.

[@UnderstandingStructures]

The concept of R is same. But I am using ASCE terminology here.

[@niranjanwatave3575]

Sir, in addition to ductility and overstrength, please add some knowledge considering redundancy factor also.
As,
1. Load distribution takes place after yielding.
2. Also yielding will take place only at one place and not in whole structure

[@UnderstandingStructures]

Thank you 🙏. Agreed

[@MuhammadSaeedYamin]

In most of cases constructor are't using mentioned steel grade and fc' for any reason.Then how our structure is over strength and we take omega factor in designing. Although it is under design not over.

Thanks for such a useful lecture

Thank you 🙏

THIS R FACTOR IS CALLED RESPONSE REDUCTION FACTOR IN INDIAN EARTHQUAKE CODE (IS 1893 PART(1) : 2016)
