Hello all
WHERE is it necessary to use #minimum #shear #reinforcement in shallow concrete #foundations? I am wondering between these two criteria: #ACI -18-2019
(phi*Vc) or 0.5*(phi*Vc)
Regards.
Ahmad.
Dear Ahmad Zamanifar
The Code says, "10.6.2.1 A minimum area of shear reinforcement (Av,min), shall be provided in all regions where Vu > 0.5ϕVc."
The shallow foundation is discussed in ACI-318-19 (Paragraph 13.3)
Thank you, Mehran
What you said comes from shear in beams & columns. (10.6.2)-ACI 318-19
Should we use it for foundation too.?
This is used mainly in beams and foundation. In foundation one more aspect of punching shear is taken into account.
T hank you, Prakash
minimum shear reinforcement area is needed when Vu is greater than phi*Vc*b*h or phi*Vc*b*h *.50 ??
secondly:
the minimum shear area is based on BEAM or SLAB criteria?
There is huge pressure of getting good impact factor on scholars now a days. On the other hand Taxonomy is a very dry subject and the concerned papers can only get citation in same group of organism.
