thanks .. these are the best notes, it really clear my doubt and also increases my interest in this subject as the way you explain is exquisite.
ReplyDeleterespected sir
ReplyDeletewill you take up advance topic like flat slab,deep beam,equivalent load method.
I do wish to prepare notes on those topics. But currently our team is engaged in a science project. So we will not be free for at least one year.
DeleteSir
DeleteThese will be taken up at the end of 2017
I want you to take subject like steel,foundation,geotechnical.
Are these on yout to do list
I am afraid, the subjects that you have mentioned are not in our to do list. Our group specialise on RCC structures. And that too, only super structure. Foundation, geotechnical, and steel are not our areas of expertise.
DeleteRight sir
ReplyDeletetopic like flat slab,equivalent frame method,deep beam, yield line will be covered ending next year(2017)
We really wish to take up those topics as early as possible. But we have no guarantee that our current project will be over by the end of next year. Also, once we take up those subjects, it will take considerable time to prepare notes and required diagrams. So I would advise you not to wait that long. Please refer advanced text books which cover those topics.
Deletesir colummn and footing design chapters are not included?
ReplyDeleteWe were not able to prepare notes on those chapters. Our team had to divert attention to another project. Please refer standard text books on those topics.
DeletePls can you listen the reference text book.

sir design of short columns under uniaxial and biaxial bending are not included/
ReplyDeleteWe have not prepared lessons on those topics. We are at present preparing some basic math and science notes. Based on that, we intend to prepare notes on basic engineering topics like mechanics and strength of materials. Unfortunately, the process is taking a very long time. Please search for other resources on short columns.
Deletecan I get soft copy of notes?
ReplyDeletepdf format of these notes are not available. But these notes can be accessed at any time. There are no restrictions.
DeleteGood notes.Very understandable.Thank you sir!
ReplyDeleteThanks for the feedback
DeleteThanks, you have done greatly well sir. God bless.
ReplyDeleteSir you are best ever i have seen .
ReplyDeleteSir please can you explain the analysis of bending moment , shear force in rcc structure and how can we use these analised moments ,forced on real projects .
Sir please ...
The bending moments and shear forces in framed structures are calculated using Kani's method, Portal method, Cantilever method etc., Those topics are related to Structural analysis. We have not prepared detailed notes on those topics. Please refer to a standard text book on those topics. Once the bending moments and shear forces are calculated, the design process can be carried out using the notes in this blog. Always cross check with the standard codes.

This is the kind of blog i was looking for from a long time, keep sharing such posts.

Very nice book for enjoying the beauty of the knowledge and understanding structural design of reinforced concrete
