Italsodescribes theprocedure fortheseismicanalysisofthemodelsandthedevelopment ofthefloorresponsespectralcurves.2.DynamicModelsTwomathematical models(onehorizontal andonevertical) fortheDieselGenerator EBuildingandonemathematical modelforthedieselgenerator pedestalareconstructed fortheseismicanalysispurposes.

Themodel,sketchesareshowninFigures1to3.Thehorizontal DieselGenerator Ebuildingmodelconsistsoffourlumpedmasses(1,2,3and4)locatedatthemasscentersofthepenthouse roof,themainroofandthetwolowerfloorelevations.

Themodelhassixdegree-of-freedoms (DOF's)pernode.Thismodelhasbeenusedforthedynamicanalysesofearthquake intwoperpendicular horizontal dir'ections.

Sincethemodelestablished reflectstheeccentricity effectoftheasymmetrical buildingconfiguration, itiscapableofproducing torsional responseduetoahorizontal earthquake.

TheverticalDieselGenerator Ebuildingmodelisessentially thesameasthehorizontal model,exceptthatishasfouradditional lumpedmasses(5,6,7and8)representing theflexiblefloors,connected byverticalspringstothefourlumpedmassesofthebuildingtoformaneightlumpedmasssystem.Thismodelhasbeenusedfortheverticalanalysisonly.Thedieselgenerator pedestalmodelhasthreelumpedmasses(1,2and3)locatedatthemasscenterofthedieselgenerator, andthetopandthemidpointofthepedestal.

ThismodelhassixDOF'spernodeandhasbeenusedforthedynamicanalysisofearthquake inthreeperpendicular directions.

TheDieselGenerator Ebuildingmodelsandthedieselgenerator pedestalmodelwerefixedatthebasesintheseismicanalysis.

Thiswasconsidered becausethestructures aresupported ontherockfoundation (Re~rence1,'2SNRCStandardR:iewPlan3.7.2)whichhasarelatively hip..young'smodulusofelasticity ofapproximately 3millionpsi.Consequently, thesoil-structure interaction effectandtheinteraction effectbetweenth'etwostructures canbeignored.Thetwomodelscantherefore beanalyzedseparately fortheirdynamicresponses.

2.1Generation ofStiffness MatricesA.Horizontal DieselGenerator EBuildingModelThe'tiffness ofthehorizontal DieselGenerator Ebuildingmodelhasbeengenerated fromafiniteelementmodelconstructed forthebuildingswallsC-3 consisting ofplateandbeamelements, andcondesned tothelumpedmasslocations atfloorelevations.

Ingenerating thiscondensed stiffness, thefloorwasconsidered toberigidinthehorizontal directions.

Thecomputation ofthemodelstiffness wascarriedoutbyusingtheMSCversionoftheNASTRANprogram(Gibbs&HillProgramNo.3030).Themodelstiffness obtainedaboverepresents thegrossstiffness ofthebuilding.

Thismodeldoesnotincludeadditinal DOF'storepresent thelateralvibrations ofthewallpanels.Theamplification effectduetothelateralflexibility ofawallpanelwastherefore separately evaluated.

usingasingleDOFsystemasdescribed inSection7.2.B.VerticalDieselGenerator EBuildingModelThestiffness oftheverticalDieselGenerator Ebuildingmodelconsistsoftwoparts.Thefirstpartiscontributed fromthebuildingwallsandisidentical tothatofthehorizontal modeldescribed above.Thesecondpartisthestiffnesses ofthefloorslabsintheverticaldirection whicharerepresented bytheverticalspringsattachedtothelumpedmasspointsatthefloorelevations (seeFigure2).Inordertoderivetheverticalspringforafloor,aseparatefiniteelementmodelofthefloorisconstructed byusingbeamandplateelementsandthefloorfrequencies areanalyzed.

Thespringconstantisthencomputedbasedonthefloorfrequency andtheverticaleffective floormassderivedinSection2.2B.C.DieselGenerator PedestalModelThestiffness oftheDieselGenerator pedestalmodelwascomputedbasedontheelasticbeamtheory.Thedieselgenerator isconnected tothetopofpedestalbyanequivalent beam.Theequivalent beamproperties wereevaluated suchthatthevibrational frequencies ofthedieselgenerator modelitselfinthehorizontal andverticaldirections areequaltothegivenfrequencies of29Hzand33Hz,respectively (Reference 8).2.2Computation ofMassMatricesA.Horizontal

One-eighth oftheseloadsconsidered aseffective andincludedinthemodelingisintendedtosimulatethedynamiccharacteristics of'hestructure (frequencies andmodeshpaes)sothattheoveralldynamicresponses (accelerations andresponsespectra)canberealistically predicted.

Themassesandmassmomentsofinertia(atlumpedmasspoints1,2,3and4)oftheverticalDieselGenerator Ebuildingmodelarethesameasthoseofthehorizontal modeldescribed above,exceptthattheverticalmasscompoents werereducedbytheamountsofeffective floormassesdescribed below.Theseeffective floormasseswereattachedtothetopofthesprings(atlumpedmasspoints5,6,7and8)mentioned aboveinSection2.1B.Theeffective massforeachfloorwasevaluated byequatingthekineticenergyofthefundamental modeofvibration oftheentirefloorintheverticaldirection tothekineticenergyoftheequivalent one-masssystemconsisting oftheeffective mass.Thisstatement canbeformulated asfo'ws:inwhichmarethenodalmasses,vwxd,v~wxd,andwisthefundamental frequency ofthefloor.darethecomponents ofthefundamental eigenvector andd,isthemaximumvalueofd.Theaboveequationcanbesimplified to:C-5 fromwhichtheequivalent massMwasevaluated, C.DieselGenerator PedestalModelThedieselgenerator masswaslumpedtothenodalpointlocatedatthemasscenterofthedieselgenerator.

Appropriate structural masseswerecomputedandlumpedtothetwonodalpoints(2and3)representing thepedestal.

Themassassociated withtheupperportionofthepedestalwaslumpedtothetopofpedestal.

Thiswillslightlylowerthefrequencies ofthedieselgenerator pedestalsystem,andistherefore considered tobeaconservative approachfromtheseismicanalysispointofview.3,ModalFrequencies andParticipation FactorsoftheModelsFreevibration analyseshavebeenseparately performed ontheDieselGenerator Ebuildingmodelsanddieselgenerator pedestalmodeltoobtainthenaturalfrequencies andmodalparticipation factors.TheMSC/NASTRAN programwasusedtocarryoutthecomputation.

5.2GroundMotionTimeHistories Onehorizontal andoneverticalsynthetic groundmotiontimehistories compatible withthegrounddesignresponsespectraweregenerated forthetimehistoryanalysisofthemodelsinordertodevelopfloorresponsespectra.Responsespectraatthedampingvaluesof1%,2%,5%,7%and10%weredeveloped usingthesetimehistories andcomparedwiththegrounddesignresponsespectra(Reference 7).C-6 6.SeismicAnalysisbyModalResponseSpectrumMethodThelumpedmassmodelsoftheDieselGenerator Ebuildingandthedieselgenerator pedestalhavebeenseparately analyzedforthefollowing earthquake casesbyemploying themodalresponsespectrummethodtodetermine thestructural responses.

Theanalyseshavebeenperformed byusingthecomputerprogramMSC/NASTRAN (Gibbs&HillProgramNos.3030).Thegroundresponsespectralcurvesdescribed inSection5wereusedasinputloads.Theprogramcomputedstructural responses (accelerations andrelativedisplacements) modebymodeandcombinethemodalresponses bymeansoftheSRSSmethodaccording totheUSNRCRegulatory Guide1.92(Reference 4).Theanalysisresultsobtainedwereusedfortheseismicdesignofthestructures.

7.Development ofFloorResponseSpectra7.1TimeHistoryAnalysesofDynamicModelslnordertodevelopresponsespectra,timehistoryanalyseswerefirstperformed onthedynamicmodels.Theinputtotheanalysisarethemodalshapes,frequencies, participation factors(seeSection3),andthegroundmotiontimehistories described inSection5.Theresulting timehistories wereobtainedateachlumpedmasslocationofthemodels.Ada~tional timehistories weregenerated atthecranerunwaygirderlocationbyusingaseparatelocalcranerunwaymodelthatincludestheflexibilities oftherunwaygirdersandsupporting columns,Theinputloadstothismodelarethetimehistoryresponses oftheuppersupporting floor.Theresulting timehistories generated attherunwaygirderlocations wereusedtodevelopresponsespectraforthecranedesign.Theaboveanalyseshavebeenperformed forthesameearthquake casesasmentioned

C-7 7.2Development ofFloorResponseSpectralCurvesTheacceleration timehistoryresponses generated fromthetimehistoryanalysisdescribed inItem7.1abovewereusedtodevelopfloorresponsespectra.Themaximumtimestepsizusedinthisanalysisis0.005seconds.Thefloorresponsespectraweregenerated atsufficient discretefrequency pointsobtainedinaccordance withtherequirements oftheUSNRCRegulatory Guide1.122(Reference 5),andatthedampingvalues(percents ofcriticaldamping)listedbelow:forOBE:0.5X,1X,2X,3X,4X,and5XSSE:1X,2X,3X,4X,5X,and7XIThecomputerprogramRESPECT(Gibbs&HillProgramNo.3914)wasusedtocarryoutthenumerical computation.

Theresponsespectradeveloped ateachfloorelevation inaspecificdirection forthethreeorthogonal earthquakes werecombinedbytheSLSSmethod.Asmentioned inSection2.1A,thehorizontal DieselGenerator Ebuildingmodeldoesnotreflectthelocallateralflexibilities ofthewallpanels.Thehorizontal responsespectrumofawallinthelateraldirection wastherefore separately analyzedbyusingasingleDOFsystemandthetimehistoryattheuppersupporting floorelevation asinput.Themaximumresponsewasthenobtainedbyenveloping thehorizontal responsespectradeveloped fromboththewallandthebuildingmodels.Theresulting responsespectraobtainedabovewerethensmoothened andbroadened by15%oneachsideoftheresponsespectralpeakstobecomethefinalresponsespectralcurves.Thesefinalspectralcurveswereusedfortheanalysisanddesignofthepipingandequipment insidethebuilding.
