Calculating Frequency & Mode Shape in STAAD - Eigen Value Extraction Method

www.CivilDigital.com
How to Calculate Mode shapes and frequencies in STAAD pro v8i using Eigen Extraction Method. Modal participation factors are required to perform dynamic analysis and response spectrum analysis in STAAD. In this example we will calculate frequencies, mode shapes and participation factors of a multi story building and we will compare the result with Rayleigh Method of extracting Frequency.

Your explanation is really good 👍👍keep going

thank you for the comment, watch our next video on response spectrum analysis

very helpful!! thank you very much!

[@dhavaladvani6301]

Very Helpful and informative.. Thanks

[@rangass70]

thanks for sharing your knowledge and very basic useful video.

[@marythomas7027]

Thanks for sharing this

[@gowthamiv4841]

it was most skillful and handy
lot more descriptions are required.

[@josev.p3029]

useful video on advanced analysis..thanks..

[@SantoshKumar-fj9hf]

Can you please explain why you have given self-weight in all the three directions and in a positive direction. Why floor load is also given in three directions?

[@uvaraj6328]

Hi in this vedio, self weight and floor load value in y direction also positive...is right? Is not practicaly possible? Pls check ...

HATS OFF... BRO...

hi Anand,
i wish to know whether my understanding is correct when it comes to the vibration of structures
1. is it ok to say that the deflection of a beam under a dynamic load is the sum of the mode shapes ? or to say that these mode shapes are obtained by fourier analysis of the original deflection?
i appreciate if you could answer this basic question of mine.. thanks for your effort.
..Rajith

[@sandroledesma8277]

do you have a example of frequency calculation of industrial building?

[@omgomase84]

Nice Information....How to calculate stiffness at each story

[@nandkumarsharma4882]

very nice vedio

[@baskaranb1199]

Great video brother.
I have doubt about this chapter. Please help me to understand that same.
1. How you assign or conform the property of the member- before this analysis? Is it calculated from dead+live load?
2. How you calculate the mode number as 10?
Stadd defaulted have 6.

How to analyze th same structure using soil springs with given value of G?

[@oscarvaronb]

how can I find the equivalent force in a concrete portico

[@OnlineCivilDigital]

[@devendra6027]

Why u apply dead load in all directions

[@robertzonacojedo8804]

how to determine the total number of mode shape in structure

[@priyajitbanerjee4346]

TOTAL NUMBER OF MODES IN A STRUCTURE CAN BE INFINITE
