Hello all
IS 456 recommends the design should of slender comp. members
should
be based on the forces obtained
after second order analysis i.e. which includes the effects of
deflections
on forces.
But ...

Yes that is unsupported length "L" ; but effective length
can be calculated more exactly by fig 26 & 27 of annex E or
as per table 28 of IS 456.

Hello
In general the check for deflection is psychological limit;
which is o.k. for floor slabs; as a person is living under some floor
and noticeable deflection of the floor may cause some worry.

Hello Mr. Biju
for determining the slenderness of a compression
member; effective length is needed; which is multiplication of a factor
with unsupported length.
Unsupported length (as the name suggest ...

Hello all
Should we check deflection criteria for
Stair slabs too?
I think it is not needed.

Hello Mr. Sidhu

If we don't provide plaster at the top of walls for resting RCC slab;
concrete will
adhere to bricks and as the slab bends bricks may detach from bottom as
these
have strong bond with ...

Hello all
anyone can make mistake.
Once Dr. S. K. Jain himself wrote during a discussion in SEFI
the courses on structural engg are most feared.
Hence, many toppers of CE may not be really good in st ...

Hello
IS 456 has given recommendation for the stripping time
of various formworks for the concrete made of OPC.
what should be the stripping time for PPC.
it will be on higher side as compared to the ...

Hello Raj
shear failure is brittle failure & flexural failure is ductile
failure.
So that is the reason we want our structures to fail in ductile mode rather
than in brittle mode.
This is the phil ...
