Steel Structure Analysis Rau Le-Tigre Warehouse Project hauv New Caledonia (ib nrab)

Steel Structure Force Analysis los ntawm 3D3S Software (rau 3-storey Steel Structure Project hauv New Caledonia)

3D3S software, tus kws tshaj lij cov qauv kev tshuaj xyuas thiab tsim software rau cov qauv steel, tau txais kev pom zoo los soj ntsuam lub zog ntawm 3-storey steel qauv project hauv New Caledonia, kom ntseeg tau tias muaj kev sib haum xeeb, kev nyab xeeb thiab ruaj khov ntawm cov qauv tsim. Ua ke nrog cov phiaj xwm kev ua haujlwm tiag tiag thiab kev txwv ib puag ncig, software ua tiav tag nrho cov txheej txheem quab yuam suav thiab txheeb xyuas, muab kev txhawb nqa kev ntseeg siab rau qhov project tsim thiab kev tsim kho.

Cov txheej txheem kev soj ntsuam quab yuam thiab cov ntsiab lus tseem ceeb raws li 3D3S software yog raws li hauv qab no: Ua ntej, tsim ib qho peb -qhov qauv ntawm 3-storey steel qauv hauv software, raug muab cov qauv tsis xws li cov tswv cuab, cov ntaub ntawv sib txuas, thiab cov khoom siv (raws li qhov project qhov tseeb steel qib thiab specification). Tom qab ntawd, thauj tag nrho cov khoom tsim nyog rau hauv tus qauv, suav nrog kev thauj khoom ntawm tus kheej (qhov hnyav ntawm cov tswv cuab steel, hauv pem teb slabs, thiab lwm yam khoom siv tas mus li), nyob load (pem teb siv thauj khoom, cov neeg ua haujlwm thiab cov khoom siv thauj khoom), cua load thiab seismic load sib haum rau thaj chaw ntawm New Caledonia, txhawm rau simulate lub zog tiag tiag ntawm cov qauv.

Thaum lub sij hawm soj ntsuam, lub software ua finite xam xam ntawm txhua tus tswv cuab steel (kem, kab teeb, purlins, thiab lwm yam) thiab kev sib txuas nodes, tsom rau kev kuaj xyuas lub axial quab yuam, shear quab yuam, khoov lub sij hawm thiab deflection ntawm cov tswv cuab, nrog rau cov kabmob muaj peev xwm thiab kev ruaj ntseg ntawm cov nodes. Rau qhov tseem ceeb ntawm kev ntxhov siab ntawm cov qauv 3-storey (xws li kev sib txuas ntawm cov plag tsev, hauv qab ntawm txhua kab, thiab cov khoom uas muaj cov khoom hnyav), cov software ua cov kev ntsuam xyuas kev ntxhov siab hauv zos kom tsis txhob muaj qhov deformation hauv zos lossis kev puas tsuaj los ntawm kev ntxhov siab ntau dhau.

Tsis tas li ntawd, 3D3S software tuaj yeem simulate cov lus teb dynamic ntawm cov qauv nyob rau hauv seismic thiab muaj zog cua loads, xyuas seb lub structural txhav thiab ductility ua tau raws li qhov yuav tsum tau tsim, thiab optimize seem loj thiab kev twb kev txuas daim ntawv ntawm cov tswv cuab raws li kev soj ntsuam cov txiaj ntsig, thiaj li ua tiav qhov sib npaug ntawm cov qauv kev nyab xeeb thiab kev lag luam. Cov txiaj ntsig kev soj ntsuam tau pom tias 3-storey steel qauv project hauv New Caledonia ua tau raws li cov qauv tsim thiab tuaj yeem ua rau muaj kev nyab xeeb ntau yam tsim qauv, ua kom muaj kev ruaj ntseg ntev ntawm qhov project.
