Conduit Support Design Review 11:00 a.m. 4 P'8C': New York, NY Ebasco Audit t

Participants:

of Ebasco B. Shakibnia Cygna Required item Comments Action By Load Factor Application In the conduit span verification calculation for configurations where dynamic analysis was done using CQC method, a new analysis using the 10% combination method is j used. For cases where computed "g" values are greater 1 than design "g" values, 2 correction methods are used:

span reduction method and tributary load factor method.

Cygna asked how these two methods are implemented.

Ebasce stated that the SAG-CP-25 will be revised to reflect load factor application. During ISO verification, the new support loads will be calculated using L' = (L + Ws)L.F. - Ws L = old trib. wt.

L' = new trib. wt..

Ws = support wt.

If the original S.0910 spans were found to ,be overstressed, their lengths would be reduced using the ,

, span reduction method, and the revised lengths would be incorporated in the new S.0910.
