Beam supporting column
Beam supporting column
(OP)
Hi
Is there any special consideration that needs to be given to a r/c beam supporting a r/c column particularly regarding lateral retraint?
I've done the simple checks (shear, monemt and deflection) The r/c beam will be cast monlithically with a 6" r/c floor slab so I presume the beam will be braced laterally. Any concerns here?
Thanks

Be careful of the deflection in this beam as it will effect the moment distribution
RE: Beam supporting column
What if it was a normal beam with a giant load in the middle? You still concerned about lateral stability?
RE: Beam supporting column
Transfer beam is critical,and columns supporting this beams become more critical when you talking about zone 3.seismic forces have to be doubled to check shear in such case,as code says.coulmn ties detail also needs attention.
check chapter 21 ACI code,special provisions for seismic design.
Even in zone 2,you need to satisfy shear+torsion criteria in beam,as well as check supporting columns for stability also.
it would be more convinient if you tell us the data like,seismic zone,building height,and the no. of floor the picked-up column has to support are.

I think this type of loading transfer mechanism will create complex stress in beam during strong Earthquake.
