[quote]Dear All,
I tend to agree with Alok on this issue.
Worldwide the developed countries have developed procedures for mandatory studies to conduct safety inspection reports of bridges and earth dams as they are quite vulnerable in a seismic event. These are essential lifelines just like lifeline buildings which deserve their justified importance.

Dear Mr Tirupathi, If u dont mind, can u pl elaborate what exactly is ur concept of a good detailing?? and as to how u will prevent it frm being a part of moment resistant frame after such a good detailing has been done??How can u detail it to avoid heavy torsion being created in such a case? It is allright if u defend this concept to reconcile some architect friends or some non technical clients (who claim to know better engineers who can deliver solutions to all the problems)...but the fact is that such columns are normally added at a much later stage in the superstructure after the foundations and columns have been cast...mostly the machine room and mumty/ Overhead tank supporting structure details are never worked out by the architects till this stage...dont you agree that it is always a compromise and not a sound str solution to agree to provide floating columns??I've also checked a society where,, the architect added penthouses on top floors and altered the str system quite substantially and added floating columns..almost after half the bldg had already come up....in such a case it was a designers nightmare to transfer even the gravity loads correctly..leave alone the horizontal forces. regards sangeeta wij
