Brian, I have no disagreement with what you are saying. I am not a lover of a cost based trigger (even though that is what I developed). I also agree that there can be some mis-interpretation in relation to what costs to use for the repair. However, it has been a fairly successful interim standard for Northridge. Far and away the best approach to determining how badly a building is damaged is to look at a loss of capacity. I began work on my repair code prior to the occurrence of Northridge. I did not move my code forward as a possibility because it was not finished. When the final ATC-43 document is complete, I intend to look again at my criteria and that of ATC-43. I was under the impression that revisions to ATC-43 were going to be made based on a letter from ATC to James Lai. My purpose in mentioning the Appendix Chapter 34 provisions which I developed and got through ICBO was to let people know that the provisions exist. In no way am I saying that a cost-based trigger is preferable to a capacity based trigger. The overall point of it all is that after next January local government needs to seriously look at some type of a repair standard. If they do not, their public facilities will simply be restored to their "pre-event condition." This leaves the impression that the building has been repaired and is now okay. Certainly not the impression we wish to leave. We have a good start with the repair code I developed (with the assistance of Dr. Sassi) and ATC-43. Hopefully, between the two documents we can come up with something which has a degree of consensus agreement.
