Q1) A major highway was implemented with concrete slabs 10 in. thick is supported by a subgrade
whose modulus of subgrade reaction is 150 pci. A 10,000-lb dual-wheel load (each wheel 50001b and
80 psi contact pressure) spaced at 14 in. is applied at (a) corner, (b) interior, (c) edge [ with two
situation: circular and semicircular with the same radius] of slab. Determine the maximum stress and
deflection in the concrete slab with equivalent contact area for mentioned locations.

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)
