C.6.3.2.1.3
Punching Shear.
Punching shear stress (psi) calculated on the basis of
4 fc
as given in Section 6.4.1.3 of this standard, provides very conservative results for two-way slabs
when compared to recent test results. Long's formula given below provides more realistic
results as it considers the beneficial effects of flexural stress and reinforcing strength.
According to this formula, punching shear capacity, Pv, is the lesser of:
