The rehab code is a step in the right direction. However, it needs the following modifications to make it more user friendly:

1. All terms used in the code should be defined properly (remember wise old Socrates who said:'the beginning of all wisdom is the correct definition of all terms').

2. The code should have more explanatory sketches.

Re.: welding on existing structures -- this need not be banned outright as suggested by Mr V.P. Agarwal. Sometimes welding of rebars may be the only solution to retrofit a structure. The point to note that welding should be done by a qualified welder under the watchful engineer who knows how welding is to be carried out. The rehab code could include such provisions.

While drafting the code, we must keep in mind that most of the building stock
in India is non-engineered. Many of the buildings, supposedly designed by
Engineers may not pass rudimentary checks for seismic design.

Secondly, methods of construction vary across the country. Recently, I was
惊喜地find that Census of India, not only counts the
population but also records methods of construction and the condition of
buildings district-wise. A look at the latest figures of Census 2001 shows
that, given the diversity of building types, any attempt at extending the draft
code to cover all of them would be a humongous task.

It is difficult to imagine that a comprehensive document with 'legal' status
can be produced any time soon. May I therefore suggest that, in its first
cycle, the draft code should cover the following in general terms, without
getting into details of construction:

1. Performance levels
2. Methods of analysis (Linear/non-linear, static/dynamic)
3. Acceptance criteria

Based on these parameters, Research Institutes / Engineers can then work out
methods of retrofitting for various building types.
