Granite, uas paub txog nws qhov nyuaj, ruaj khov, thiab qhov zoo nkauj, tau siv dav dav tsis yog ua cov khoom siv kho kom zoo nkauj xwb tab sis kuj yog cov khoom siv hauv kev ua haujlwm raug thiab kev tsim vaj tsev. Hauv kev tsim qauv niaj hnub no, yuav ua li cas txhim kho kev ua haujlwm ntawm cov qauv los ntawm kev ua kom zoo dua ntawm cov duab ntawm cov ntoo granite tau dhau los ua ib qho tseem ceeb, tshwj xeeb tshaj yog thaum cov lag luam nrhiav ob qho tib si cov qauv sib dua thiab kev ua haujlwm zoo dua.
Raws li ib qho ntawm cov khoom tseem ceeb uas muaj peev xwm thauj khoom hauv kev tsim vaj tsev thiab cov khoom siv precision, qhov kev tsim qauv ntawm lub beam granite ncaj qha cuam tshuam rau nws lub peev xwm thauj khoom, qhov hnyav ntawm tus kheej, thiab kev siv cov khoom siv. Cov kev sib tshuam ib txwm muaj - xws li cov duab plaub fab lossis I-puab - tau ua tiav cov kev cai tsim qauv yooj yim ntev. Txawm li cas los xij, nrog rau kev nce qib ntawm kev siv tshuab xam zauv thiab kev thov kom ua haujlwm tau zoo dua, kev ua kom zoo dua cov duab sib tshuam no tau dhau los ua qhov tseem ceeb kom ua tiav kev ua tau zoo dua yam tsis tas siv cov khoom siv tsis tsim nyog.
Los ntawm qhov pom ntawm cov qauv kho tshuab, qhov zoo tagnrho granite beam cross-section yuav tsum muab qhov ruaj khov thiab lub zog txaus thaum txo qis kev siv khoom. Qhov no tuaj yeem ua tiav los ntawm kev ua kom zoo tshaj plaws geometry uas ua kom muaj kev faib tawm ntawm kev ntxhov siab ntau dua thiab tso cai rau kev siv tag nrho ntawm granite lub zog compressive thiab bending. Piv txwv li, kev txais yuav qhov kev tsim qauv cross-section sib txawv, qhov twg lub beam muaj cov ntu loj dua ntawm thaj chaw ntawm lub sijhawm khoov siab dua thiab cov ntu nqaim dua qhov twg kev ntxhov siab qis dua, tuaj yeem txo qhov hnyav tag nrho thaum tswj kev ua kom zoo.
Cov cuab yeej niaj hnub finite element analysis (FEA) tam sim no ua rau nws muaj peev xwm ua kom pom tseeb ntau yam geometries thiab cov xwm txheej thauj khoom nrog qhov tseeb zoo kawg nkaus. Los ntawm kev ua kom zoo dua ntawm cov lej, cov engineers tuaj yeem tshuaj xyuas cov cwj pwm kev ntxhov siab-nqe, txheeb xyuas qhov tsis zoo hauv kev tsim thawj, thiab kho cov kev teeb tsa kom ua tiav cov qauv zoo dua. Kev tshawb fawb tau qhia tias T-zoo li lossis lub thawv-zoo li granite beam seem tuaj yeem faib cov khoom thauj thiab txhim kho kev nruj thaum txo qhov hnyav - qhov zoo dua hauv kev tsim kho thiab cov khoom siv precision.
Ntxiv rau qhov kev ua tau zoo ntawm cov khoom siv, granite cov qauv ntuj thiab qhov zoo nkauj ntawm qhov muag kuj ua rau nws yog cov khoom siv uas txuas kev tsim kho thiab kev zoo nkauj. Cov duab txiav zoo tshaj plaws - xws li cov qauv geometries lossis hyperbolic - tsis yog tsuas yog txhim kho kev ua haujlwm ntawm lub nra xwb tab sis kuj qhia txog kev nyiam pom tshwj xeeb. Hauv kev tsim vaj tsev, cov duab no pab txhawb rau kev zoo nkauj niaj hnub thaum tswj hwm qhov kev ua haujlwm raug thiab kev ruaj khov uas granite paub zoo.
Kev koom ua ke ntawm kev tsim kho tshuab, kev tshawb fawb txog cov ntaub ntawv, thiab kev ua qauv suav lej ua rau cov neeg tsim qauv thawb cov kev txwv ntawm qhov granite tuaj yeem ua tiav raws li cov khoom siv qauv. Raws li kev siv tshuab simulation nce qib, cov engineers tuaj yeem tshawb nrhiav cov qauv tsis zoo thiab cov qauv sib xyaw uas sib npaug kev ua haujlwm ntawm lub tshuab, kev ruaj khov, thiab kev sib haum xeeb ntawm qhov muag.
Xaus lus, kev ua kom zoo dua ntawm cov duab ntawm cov pob zeb granite yog ib txoj hauv kev zoo los txhim kho kev ua haujlwm zoo thiab kev ruaj khov. Nws tso cai rau kev siv cov khoom siv tsawg dua, txhim kho lub zog-rau-qhov hnyav, thiab txhim kho kev ua tau zoo mus sij hawm ntev - tag nrho thaum tswj hwm qhov zoo nkauj ntawm granite. Raws li qhov kev thov rau cov qauv siab thiab kev kho kom zoo nkauj txuas ntxiv mus, granite, nrog nws cov khoom zoo nkauj thiab kev zoo nkauj tsis muaj hnub nyoog, yuav tseem yog cov khoom siv tseem ceeb hauv kev txhim kho cov qauv tsim thiab kev lag luam tiam tom ntej.
