Why such presentation seen in environmental engineering and environmental management ???

Excellent presentation. Thank you.

Thanks a nice graphical explanation. Easy to understand a complex subject.

Very good explanation

Complete insight of this topic

Thanks doc, its easy to understand for me!!

Dr Nafie is a talented teacher! 13 minutes of pure enjoyment, thank you very much! 🙂

Dr i appreciate for all your efforts, I have a question, are the column dimensions are same from floor to floor or it's decrease

Excellent. Simplifying the RSA equations into simple term

Thank you very much sir

how do you work out the moments at point A and B on the inclined beam?

This might be one of the greatest video on vibration that UA-cam have upload ever! THANKS!

Hello Sir, really want to express gratitude for this video, its amazing that in 30 minutes we feel so confident and energetic of this Spectrum concept which had always been revolving on top of the head for such a long period.

I passed CA seismic exam on my first go. Walked away feeling like I didn't have a good grasp on the topic. You did in 15 minutes what I couldn't learn in 100 hours of studying. Thank you.

Hi Dr Nafie, how did you obtain the mode shape? I would like to obtain a simple expression for idealizing a building as a prismatic member, I think it can be done, but the hardest trick is the mode shape. And, deflection of the tip of the building I think can also be obtained from the modal participation multiplied by acceleration multiplied by mode shape.

After a long time research i got the meaning of Response Spectural Curve and it's usage. can you please explain about natural frequency in detail as well?

Thank you!

Your work is awesome Dr. Please keep it like that.

Such a valuable lectures, May Allah bless you🤲🏼

Undoubtedly great video, thank you. Constructive criticism from a non-engineer (and general advice to presenters of all kinds): Give the point of the slide at the beginning instead of the end

Best

Great explanation. Congrats !

excellent

I had forgotten all these things that I had passed in the master's degree - this was a very good overview of the structural dynamics course for me - thank you Dr. Nafie - it was so good.

Thanks 💜🤗

Thank you, corelate your theoretical lecture with practical one using design software this is as a feed back.

May I know How to obtain the value (VB)EQ=414 kN in the given example?

May I know How to obtain the value (VB)EQ=414 kN in the given example?

Thank you sir for making my understanding to this topics very well, you make a hard one become easier

Thank you Professor

I have to write a paper where this appears and all the textbooks where just filled with absurdly complicated graphs and equations. Thank you so much for making this! It really helped me out a ton

Thank you very much!!!

Just want to drop by and say, "Thank you" for this lecture. This is gold!

Very useful information about response spectrum.

you just explained a whole course in 13 minutes, and I feel safe that there are others like me

If one can understand what you teach in one sitting, then you know you have done a good job. I subscribed immediately after watching the video. Thanks. Civil Engineer from Lagos, Nigeria.

Excellent

It is such a valuable lecture. I don't think someone can explain better than this. Too much appreciated and Very thankful to you sir.

for a roller support, how is the motion restricted in the x-direction when the applied force is causing pullout of the support?

Amazingly explained. Really appreciated and thankful.

Quite impressive, love the way of teaching

I'm glad to find this peice of treasure. It helped a lot with my paper work

Thanks for this valuable details

very well explained, thank you it was really helpful

Time history analysis also and use softwares as well detail information

Thank you , very match !!! You helped me.... to understand....

Wonderful video, very informative and useful

Really helpful

nice explanation sir....

Great explanation. Please make video on how we use this shear force for further design
