�In India we are designing a two storey r.c.c structure and 51 storey high end residential�building�from the same code without any�clarity what as a structural demand's that are needed to withstand dynamic

�forces for tall structure� . My�personal�opinion�in this matter is that we should have earthquake zone wise different codes for different level of buildings�considering geotechnical aspects also�

1. upto 5 storey


2. 6 to 15 storey


3. 16 to 30 storey
�
4. 30 storey plus


when we compare china with us there is no difference but a large displacement you can say of mind set. In china it is there state policy to excel in all phases of engineering ,�government is pushing hard to


�prove to world that they can match the world and at the same time can be best were as in India for decades ENGINEERS BILL could not pass, pile foundation code's are quarter century old, earthquake


�code is a decade old, we are still living with old codes making tall building and special structures . An era of 5 kg/sq feet steel upto 20 storey , non tower area 8 -9 kg/sq feet steel, 40 storey 8 kg/sq feet should be


�banned and�punished�as these are the codes set by real estate with structural drawing shops , not with structural engineers.Compromising tall structures is just like tickling time bomb .�


From every earthquake we learn something new and revise us and reward us simultaneously that structure we had made withstand the test of time or not. from�san francisco E.Q �we learned about fire,�


hospital performance , from kobe we learnt about�liquefaction�can also be a giant killer.


When structural�engineers�from�California�or new�York�can make there own EQ guidelines why not S.E.F.I �can do the same , and make a practice to follow these norms and update the S.E.F.I


�( E.Q.CODE) in every three years , collect the money from all educational institutions , individual and�corporate's, state govt and various other agencies�, make a�committee under chairmanship of


Dr. S.K.JAIN and�committee�should�compromise�academicians�, researchers , working professional from all four sides of India to come on a stage and prepare guidelines with strict parameters and clear


�definition�of do's and don't. rather than �follow the present code which is not even clear of time period calculation to be adopted , although draft code by Dr. S.K.JAIN has clear�definition.


It's my personal�opinion�that first code's should be revised then we can have another tall e-conf, with some�fruitful�discussion and conclusion.


Regard's

I fully agree with what Mr Joshi has said /proposed.It is high time when we need �to go to the NGOs and other such bodies before we meet with one more natural calamity . We must do something now so that we need not do that post EQ.And when we have faculty experts like Shri SK Jain ,it is certainly possible to update our codes and design methods �and thus prevent any more disaster.I am hopeful that SEFI will consider this positively and will come out with something fruitful in the interest of the nation when most parts of the nation are becoming EQ sensitive gradually. Er suneil mehtaALWAYS� BE POSITIVE !!!!
