RE: Shear

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Curt:

I am only speaking here of the exception for concentrated loads (located
closer to the support than "d") that appears in section 11.1.3 b.  It is
illustrated in Figure R11.1.3.1 d. You must include these concentrated loads
in your shear calculation for Vu. I believe only uniform loads within a
distance "d" can be ignored. The commentary elaborates more on this
requirement.

Jim,

I believe that the ACI section you mention does permit the loads closer than
"d" to the support to be ignored (or in otherwords Vu shall be as that
computed at a distance "d" from the face of support).  There are exceptions
that are discussed in the commentary.

Does anyone know why for Concrete design per ACI 318-95  11.1.3.1 you are
not allowed to ignore concentrated loads within a distance "d" from the
support for shear yet for Wood design, you can ignore all loads within a
distance "d" from the support per NDS '97 3.4.3a (Figure 3D). Shouldn't
proceedures for wood and concrete be the same? Is NDS ignoring some effect
that they should not be?
