Time History Analysis In Staad Pro v8i - Structures under Seismic Accelerations

Time History Analysis In Staad Pro v8i - Structures under Seismic Accelerations
civildigital.co...
Analysis of a structure, applying data over increment time steps as a function of:
--Acceleration
--Force
--Moment, or
--Displacement
It provides the response of a structure over time during and after the application of a load.
The Time History Response of a structure is simply the response (motion or force) of the structure evaluated as a function of time including inertial effects.
Stage One
Time History Function Definition
Time Step
Time Increments or Δt used for analysis.
Output time-step size should be small enough to provide sufficient resolution for analysis.
The required resolution is dependent upon the characteristics of applied loading and such structural properties as the natural periods.
The sufficiency of resolution may be determined by decreasing the time-step size until it is small enough to not affect results.
Function Definition
Analysis Parameters
Arrival Time is the time at which a load assignment begins
Can be positive, negative, or zero
Begins at time zero, by default
Portion of the input which occurs before time zero is ignored for negative arrival time
eg: an arrival time of -5 will neglect the first 5sec of the input function.
When load type is set to Accel, the scale factor should be specified to produce the acceleration desired in the current units when multiplied with function.
If function is in the current units, the scale factor should be set to 1.0.
eg: if time-history data is in cm/sec/sec, and current units are ft/sec/sec, then a scale factor of
1ft / 30.48cm = 0.0328 should be used.

Good one...thank you

[@nandkumarsharma4882]

very educative of a building and it helped me to do time history analysis thanks

[@snjkumarbr]

Thanks for all your videos.....it helped me lot....

[@stanleyjones92]

Thank you . Useful

[@amlanjyoti2]

Very informative video, tnq

[@ravindrasaini4778]

great job sir

[@samaarunkumar3027]

Sir can u please give me a info about how the time vs acceleration values are obtained as a input file

[@aartichopra124]

Yes, even I want to know how to obtain those values.

[@swagatomajumder6664]

Thanks a lot!!!!!

[@mmchengcheng1]

Thanks Man! That was really helpful in my project! I am just confused about the differences between "Load Combinations" and "Repeat Load" which bring different results in dynamic analysis... In your video, load combination was used. Can you explain that a little bit?
Thanks!

[@thetskshow5408]

Regarding I want to know scale factor how did u fix 32

[@leeanddebsidwell1425]

Hi there, this was very helpful but at the end it refers to another tutorial on Time History using force functions. I cant seem to find this tutorial anywhere, does it exist and if so can you please end me a link. Thanks

[@Jags22079]

Can you provide Some videos or links to make basics of Stadd for the beginners

[@pawankhade21]

Very useful, is there any way for stiffness degradation in stadd, please upload if u know

[@Jags22079]

Thanx man

[@rusheddad8547]

I need help regarding the buckling analysis in STAAD.Pro. Can you please upload the video of carrying out buckling analysis in a column. I would appriate a lot

[@thetskshow5408]

Hi how did u calculate time acceleration pl advise that

[@suliman9058]

what does it mean having negative x TH base shear please?

[@alenrider]

what is the procedure to model ribbed slab with staad pro

[@husseinnasser1475]

thanks

[@kalyanikaremore8477]

can you please make video on "time history analysis for moving load on metro bridge". If you know any thing about this topic please make video.

[@nsneenusk]

can u please explain how to provide scale factor? what value should we provide as scale factor ?

[@manoharmanu6734]

plz provide the link for time history analysis using sine function , it would help me in my project

[@er.kalyanikaremore528]

Can you explain time history analysis for moving load

[@ManoharParigala]

Please provide the txt file in the description

[@akashparashar8126]

Hi, can anyone tell how to apply impact force due to falling object on staad pro?

[@abhishekkaushik9396]

can you provide me with the text file which had the accelerations w.r.t. time

[@PhilipLukeK]

can u give me the link of the video of analysis using sine wave...

[@anantsojitra4611]

can you help me out in my staad model bhuj earthquake time history analysis......

[@moinuddin5593]

how to generate that external file you are using, in which acelleration values are there ?

[@AnandPaul]

You can go to strongmotioncenter.org/ to download earthquake data for any location..

[@kuswantosolossawantosoloss863]

thangk to ILMU apload time history analisis to STAAD..

[@indranilbal9507]

Can you please share that eq data please?

[@krishnareddy7895]

where we get input external file, i am from india.

[@anantsojitra4611]

can you help me out in my staad model bhuj earthquake time history analysis......

[@pulkitmishra4918]

Can you please tell me how to get the external file containing the required values in the notepad?
