D14.C.6.5 Shear
Per section 13.4.1, the factored shear resistance, Vr , developed by the web of a flexural member, shall be taken as
Vr = ϕAv fs
where= |
-
f s = 0.66f y when
where- kv
= = the shear buckling coefficient defined as:
-
fs = fcri when
where- fcri
= - kv
= = is as defined in (a)
-
fs = fcri + ft when
where- ft
= - the tension field post-buckling stress defined as:
= ka(0.50fy - 0.866fcri)
- ka
= - the aspect coefficient defined as:
-
fs = fcre + ft when
where- ft
= - the tension field post-buckling stress defined as:
= ka(0.50fy - 0.866fcre)
- fcre
= - kv
= - as defined in (a)
