coupling beams modeling in ETABS

coupling beams modeling in ETABS

(OP)
hi every body
  my problem that coupling beams between shear walls modeled as shell element in ETABS model for 40 story tower. so it is subjected to heigh shear force . then i thought to reduce shear stiffness for coupling beams . but no way to do this in ETABS .any body have thoughts about this subject. any thoughts will be very usefull
thanks

RE: coupling beams modeling in ETABS

I don't understand why you can't use shell elements for the coupling beam also. You could use a different area element definition for these shells than for the rest of the shear walls. You could either accomplish this by either making these elements thinner or by using the property modifiers.

You should expect huge shears in these. If you were not getting huge shears, I'd think it was wrong.

After I sent my reply, I thought of something else.

I don't mean to sound disrespectful, but it's pretty terrifying that you're designing a 40-story building with ETABS and don't know how to do this. This is about 2 steps above ETABS-101.

I recommend that you get with your supervisors and make sure that all of your modeling assumptions and methodologies are correct.

Perhaps I'm misunderstanding your question and it's not as bad as it sounds.

Hi Amirgomma,

You can change the property modifiers of that coupling beam. If you use high strength concrete, you can still go ahead of limiting value of 5MPa.
