Conduit Support Design Review 11:00 a.m.
4 P'8C':
Ebasco Audit New York, NY 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 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.
