ABAQUS Tutorial Cyclic loading Analysis of Steel Framed structure

[@abyssiniafactnews1751]

sir Thank you for the the knowledge you shared.my question is why you use 1 in the displacement in the Excel it was 240mm or for the time?

[@KSSE_Engineer]

Please check the video there An amplitude was provided.

[@abyssiniafactnews1751]

ok i got it.Thank you for your quick response!!!

[@hosnitaleb7574]

Nice, keep going and thank you

[@prakharjung4603]

Thank you for the video. Its very informative.!! You have taken the reaction force for the hysteresis plot at the set defined at top left column( where you assigned U1 displacement), rather than on the fixed boundary conditions at the column base. Why is it so? Isn't the reaction force determined from the fixed boundary conditions??

[@KSSE_Engineer]

It's Newton's third low. but you also can get that reaction force from the bottom node which is equal to the sum of the bottom nodes. just do a quick test for your concern.

[@prakharjung4603]

Did it came identical for your model in both cases the hysteresis plot/ reaction force?

[@dendisephanie4974]

good video sir may i ask you about the cyclic setup? i need curve like you but from the code (i mean it written on the code like ACI or etc) looking for that curve but i only found the curve for column or beam, can you help me?

[@KSSE_Engineer]

Hi there , please check the tutorial I have explained it . Additionally the curve is explained in ATC 24 and so many published articles.

[@herbertoryem]

How do you calculate the time and the displacement using the number of cycles and the drift angle (theta) from the AISC loading sequence?

[@KSSE_Engineer]

Check it in the video carefully.

[@herbertoryem]

@@KSSE_Engineer In column L, you said you accepted a maximum of 3 minutes, so how did you get 1500/87?, this is 25 minutes since 25x60=1500

[@engineering789]

Sir it is Nice and informative,but I have a question that at 0:40 you said we have accepted 3 mnt. As cyclic time and based on it you have created cyclic data, so can you explain about taking 3 mnts and what is importance of this time?

[@KSSE_Engineer]

If you want to know properly check this code ATC 24 . Everything is explained well for cyclic analysis and experimental testing .

[@doddasrinivas6348]

Sir, can you please let me know from where that 1500 came in column L.

[@engmohamadshehab4020]

Sir i need to ask you how to conduct and get the cyclic data as time and displacements according to ATC-24, because in my case i need to simulate a test and the maximum displacement applied in that test is 146 mm, and the number of cycles used are 24, i just need these data in order to continue my simulation. Thanks in advance sir.

YOU CAN FOLLOW THE FEMA 461 GUIDELINES TO PRODUCE CYCLIC LAODING

[@niteshshrestha2835]

Great video!! Is it necessary to consider the gravity load of the steel frame in such analysis?

[@KSSE_Engineer]

No

[@Sathyasav]

Tq sir , very informative I am putting curved dampers at the beam and column connection, can u tell me how to connect curved dampers to column or beam with pin connection.

[@KSSE_Engineer]

There are many connector in the intersection part you can use any of them that’s suitable for your model.

[@Sathyasav]

Sir any reference video

[@Sathyasav]

Sir how to get time history data

[@niteshshrestha6204]

I tried for cyclic loading of rc frame in abaqus. The hysteresis plot appears to be much higher values than experimental work. I have used kinematic hardening for rebars/steel and compression, tension recovery 1,0 for concrete. Can you suggest any probable cause for this?

[@KSSE_Engineer]

You should consider bond-slip between concrete and rebars . If you can’t it’s better to use opensees software.

[@niteshshrestha6204]

@@KSSE_Engineer only bond-slip may be the cause for it?

[@lintapaul3108]

Sir I'm doing CFST column steel beam joint connected with bolted connection subjected to cyclic loading at beam end After running I'm not getting strength degradation portion in the result In property module, I have given elastic and plastic property with combined hardening Still I'm not getting strain softening region Please help.

[@KSSE_Engineer]

There are two options; one may be your joint didn't reach the yield strength, therefore increase the amplitude of the load; two, you can use another material, such as Janson-cook damage or shear failure.

i need to know .. how the loading in created column G & H

[@KSSE_Engineer]

Check the video carefully.

[@sajidsarabi5748]

how can contact with you sir

[@KSSE_Engineer]

There is my email and other contact details in this channel “ About” .

[@intankurotaaini8039]

can you add a book about the example for this video?

[@KSSE_Engineer]

There is no book, but you can find some research articles. Just google steel frame in science direct or research gate .

[@landrytim8595]

could you please re-upload yr videos (previous channel) about rayleigh damping

[@KSSE_Engineer]

not available now , later I will make another
