ACI 318-19 18.7.6.2 Transverse reinforcement

[pxsm]

18.7.6.2.1 Transverse reinforcement over the lengths lo, given in 18.7.5.1, shall be designed to resist shear assuming
Vc = 0 when both (a) and (b) occur:
(a) The earthquake-induced shear force, calculated in accordance with 18.7.6.1, is at least one-half of the maximum required shear strength within lo.

Hi everyone,
I need some help. I don't know what "the maximum required shear strength" is. Is it the factored shear that I find from a frame analysis?
Thanks in advance

Assuming you are dealing with a special moment frame, the Maximum Required Shear Strength is the shear strength corresponding to the development of probable flexural strength ,M_pr, at each end of the beam. This required shear strength should not be taken less than the factored shear strength determined from your frame analysis.

Read up Commentary R18.6.5 and look at Fig. R18.6.5 for clarity.
