24 - Classical Modal Analysis of Building Structures and Interpretation of Results Using CSI ETABS 

You Explained this perfectly. Thanks. I have cleared all my doubts

You are teachings are excellant I am from India. I appreciate the explanation

Thank you, sir. Now I can understand the basics of modal analysis clearly.

The efforts generated by the spectrum in the structure are absolute values, which cannot be combined with gravitational loads (which have a sign convention according to the direction of the force). How can you give a sign to the forces generated by the spectrum and be able to combine them with gravitational charges and so on?

Thank you for your detailed explaination sir. Much appreciated.

How to deal with a couple mode?? How to scale the response spectrum??

greetings from Germany, nice video

Excellent explanation

Hi. Thankyou for the video. Very informative. Can you tell the difference between Eigen and Ritz Modal analysis?. I have searched the internet but didn't get any satisfactory answers.

Thanks for wonderful lecture

Results for modal load Case and RSX,RSY load are different...why

*_Fantastic sir. Super sir_*

Sir Najam, thank you.. Is it possible to build with the firsts mode as torsional?... considering that its drifts are less than 50% in the elastic range

How we can get mass participation factor sir? you didnt explain it

Excellent

how can i compute the modal assurance criterion (MAC matrix between experimental and numerical results)?

Can you share your lectures on Plastic Hinge Model of RCC Column and Beam using ASCE 41 in PERFORM 3D?

Dear sir, Is response spectrum analysis is same as modal analysis...

How to chk period sec . On first three mode on Model is ok or not ok

SIR how can i convert this mode shape value in format as top storey with mode shape 1.

0:47 *_How can i get this deflected video in etab ?. please help me._*

Great

👍🏻👍🏻
