Thanks 😄

You made it much easier than it seemed 🙏

Other than those guys reading the slides word by word, this engineer knows what he is talking about, amazing job!

I have watched these two sessions about Modal Response Spectrum analysis multiple times and always enjoyed them. Excellent explanations and insights :) Thanks a lot Dr Nafie :)

thanks sir

How to get tha Equalent Base shear of 414KN.. Anyone is having idea about this please share.. Thanks in Advance😊

Thank you sir

I don’t understand the seismic force on X and Y direction. Can anyone help?

Interesting and clear videos. I like the animations of failure at 5:20, what program did you use to make it? Thank you.

Brilliant

INFORMATIVE THANK YOU❣

This is fabulous, thank you. The seismic requirements have puzzled me completely, but these videos have made them crystal clear. Thanks.

thankyou for detailed analysis & examples

Great ❤

Hi Sir, Thanks for very useful video. Can you please guide me how can I make that 3dof system oscillatian animation. Thanks in advance

Pls can we have more videos from you. This is the best explanation i hv found on Response Spectrum . A big thank you

Very good video. Thank you

respect you and your animation, very comprehensive. Thank you

How you calculate minimum horizontal force of 119 KN????

Excellent Explaination

Really good content.

Sir How did you find For mode-1 , T1=0.282sec, Mode-2 T2=0.065sec, T3=0.059Sec. Please sir kindly explain.

Wow, so simple explanation of this complex looking concept. Amazing, thank you Dr Nafie

Nice explanation...❤

This is an excellent explanation. Thank you so much!

1. We scale up the base shear obtained by Response Spectrum Analysis (RSA) to that of the Equivalent Lateral Force (ELF) method. But when RSA base shear is higher than ELF method, why don't we scale down RSA to the ELF ?? 2. Response acceleration should be zero at T = 0 in response spectrum curve. But response acceleration is starting at coordinate equal to 40% of SDS (by formula). Why is it so ??

Wow... this lecture is very excellent.. you answer me about many question in my mind .think you professor and please continuous like these topic.

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
