Dear All
I agree with the other SEFI members that a retrofitting Code was long
required and
this is a good move in the right direction. I congratulate Dr Rai and others
for coming
up with this document.

I have the following comments/queries:
a) The proposed code appears to be primarily meant for RC structures and
calls out
masonry structures only in passing in Section 7.4.3. Given the imbalance of
RC vs.
masonry structures, it may make sense to eliminate masonry structures from
this code
completely and let that be called out in separate code already existing for
the same.
b) Clause 7.3 � Acceptability Criteria- It appears that both the sub-clauses
a and b
have to be satisfied ( it is not �or�) The b sub-clause required ensurance
that critical
elements failure will not lead to loss of stability or progressive collapse
which is to be
verified by push-over or similar analysis. This appears to be a bit over the
top
考虑到在印度几乎没有人this even for new
buildings. This
clause needs a review.
c) Section 8.5 �This is rather skeletal and may need more fleshing out. The
seismic
strengthening options may also discuss fibre wrapping and other newer
technologies,
for examples. Details of how to treat beam-column joints are missing.
