A surve, presented at the meeting, of forsen versus break sine (liquid breake) with break opentas time as a parameter is attaebed.
l Thors are too interesting results presented on the surve. First, if one eeeld prove a 0.1 see break openias time, a redusties of wppesa.
imately 60% in loads would result. Seoemd, if ens uses as instantamus break opening time, assentially no redesties la foreas j
would rossit for redsettens in break sine from 1001 (design break, i
6.12 f t ) deun to 65%. This latter feature appears to be a shar-j seteristia of the Rip Code which assumes lumped modes and equilibrius l

same amaner as more elaborate sedes such as Durst (pW0e) er Watera n - mar (gaiser). We believe that further reriew in this regard will be required.
