Calculate the maximum shear stress that can be
resisted, VR/bwdv, by Beam A and B using
(a) The CSA simplified method of shear design
(b) The old ACI method of shear design (replaced
in 2019)
Comment on the differences between the CSA
and older ACI code that you see in answering
questions (a) and (b). Also comment on the
resulting safety of large beams and slabs without
stirrups designed using the codes. (Bear in mind
that the CSA code has been repeatedly shown to
very accurately predict the shear strength of
beams tested in the laboratory)

What is Schmidt Hammer Test & Point Load Test?
pls explain Briefly
In accordance to NSCP 2010, the calculation of the required strength U shall be at least equal to the effects of
the factored loads below where the effects of one or more loads not acting simultaneously shall be investigated:
U=14 (D)
U=12 (D) +1.6 (L) + 0.8 (W)
U=12 (D) +1.0 (E) +1.0 (L)
U=0.9 D+1.6 W
Results from elastic analysis of a concrete beam yields the following values of un-factored (service) moments:
Dead load moment = 50 kN-m
Live load moment = 80 kN-m
Wind load moment = 60 kN-m
Earthquake load moment = 100 kN-m
Determine the value of the factored moment (kN-m) that will be used in designing the member.
