Kev txhais lus dav dav ntawm cov cuab yeej siv tshuab: Lub zog, nruj, hardness, deflection, elasticity, toughness, rigidity thiab yas
Hauv cov txheej txheem engineering, kev sim cov khoom siv, kev tsim cov qauv steel thiab cov phiaj xwm tsim kho, cov cuab yeej cuab yeej cuab tam yog lub hauv paus tseem ceeb rau kev txiav txim siab cov khoom zoo, kev ruaj ntseg thiab kev pabcuam ruaj khov. Cov ntsiab lus xws li lub zog, tawv, hardness, deflection, elasticity, toughness, rigidity thiab plasticity feem ntau tshwm sim nyob rau hauv cov qauv specifications, cov ntaub ntawv xeem thiab cov qauv kev lees paub. Cov yim qhov tseem ceeb no yog qhov yooj yim rau kev tsis meej pem hauv kev siv engineering siv. Cov kab lus no tau txheeb xyuas cov ntsiab lus, cov ntsiab lus ntawm engineering, qhov sib txawv tseem ceeb thiab kev siv cov xwm txheej ntawm txhua qhov ntsuas, ua kom tiav thiab yooj yim -rau- nkag siab txog cov cuab yeej cuab tam kev paub rau engineering cov neeg ua haujlwm.
1. Lub zog
Lub zog yog hais txog lub peev xwm siab tshaj plaws ntawm cov khoom siv lossis cov khoom siv los tiv thaiv kev puas tsuaj nyob rau sab nraud. Nws yog qhov ntsuas tseem ceeb los ntsuas seb tus qauv lossis cov khoom puas yuav tawg, tawg lossis tsis ua haujlwm, uas ncaj qha txiav txim siab txog kev nyab xeeb ntawm cov khoom siv hauv tsev thiab cov khoom steel.
Hauv kev xyaum ua engineering, lub zog tau muab faib ua tensile zog, compressive zog, shear zog thiab dabtsi yog khoov zog. Rau cov qauv steel thiab cov pob zeb ua vaj tse, cov khoom muaj zog thiab qhov kawg ntawm lub zog yog qhov tseem ceeb ntawm kev lees paub. Thaum cov khoom siv sab nraud dhau ntawm cov khoom siv lub zog txwv, cov khoom yuav tsim kev puas tsuaj xws li tawg thiab tsis ua haujlwm. Lub zog daws qhov teeb meem tseem ceeb ntawm"txawm hais tias cov khoom yuav tawg", thiab nws yog lub hauv paus lav ntawm cov txheej txheem bearing kev ruaj ntseg.
2. Kev nruj
Kev nruj yog txhais tau tias yog lub peev xwm ntawm cov txheej txheem tiv thaiv kom tsis txhob deformation nyob rau hauv sab nraud load, xav txog qhov nyuaj ntawm cov qauv deformation. Sib txawv ntawm lub zog uas tsom mus rau kev puas tsuaj tsis zoo, nruj tsuas yog lub hom phiaj deformation kuj, txawm tias cov khoom puas los yog tsis.
Cheebtsam uas muaj siab nruj tsis yooj yim rau deform nyob rau hauv load, thaum uas tsis muaj zog yuav ua rau ntau tshaj dabtsi yog khoov, twisting thiab hloov chaw ntawm cov qauv. Nyob rau hauv lub tsev tsim thiab reinforcement engineering, tsis txaus rigidity yuav ua rau ntau yam qauv deformation, tawg expansion thiab tsis zoo tag nrho cov stability, txawm yog hais tias tus tivthaiv tsis ncav lub zog tsis ua hauj lwm txwv. Nyuaj daws qhov teeb meem ntawm"yuav ua li cas yooj yim tus qauv deforms", thiab yog qhov ntsuas qhov tseem ceeb los tswj cov qauv deformation thiab kev pabcuam kev nplij siab.

4. deflection
Deflection yog ib qho kev ntsuas tus lej tshwj xeeb, xa mus rau qhov siab tshaj plaws linear deformation hloov chaw ntawm dabtsi yog khoov Cheebtsam xws li kab teeb thiab slabs nyob rau hauv ntsug load. Nws yog ibCov ntaub ntawv ntawm kev ua haujlwm nruj, es tsis yog cov khoom siv.
Deflection yog siv ncaj qha rau kev lees paub thiab kev tswj deformation. Rau steel choj kab teeb, lub tsev hauv pem teb kab teeb thiab steel truss Cheebtsam, ntau deflection yuav ua rau cov qauv kev co, phab ntsa tawg, tsis sib npaug kev ntxhov siab thiab txo cov kev pab cuam lub neej. Hauv kev tshawb nrhiav engineering, tus nqi deflection yog siv los txheeb xyuas seb qhov kev nruj ntawm cov qauv ua tau raws li cov qauv tsim. Cov deflection me me sawv cev rau cov txheej txheem siab nruj, thiab loj deflection sawv cev tsis txaus. Deflection daws qhov teeb meem ntawm"ntau npaum li cas cov qauv khoov".
5. elasticity
Elasticity yog lub hauv paus ntawm cov khoom siv kom rov zoo li qub tom qab tshem tawm sab nraud. Thaum cov khoom nyob rau hauv lub elastic txwv, lub deformation generated los ntawm sab nraud quab yuam yog reversible kiag li, thiab tsis tas yuav residual deformation yuav raug tsim.
Tag nrho cov ntaub ntawv tsim qauv muaj qhov txwv tsis pub muaj kev txwv. Hauv kev tsim qauv, kev pabcuam kev thauj khoom ib txwm raug tswj nyob rau hauv theem elastic deformation kom ntseeg tau tias lub tsev tuaj yeem rov qab tau nws lub xeev qub tom qab cov kabmob thauj khoom thiab zam kev puas tsuaj deformation. Elasticity daws qhov teeb meem ntawm"txawm hais tias lub deformation tuaj yeem rov qab tau", thiab yog tus cwj pwm tseem ceeb ntawm kev pabcuam ruaj khov.

Toughness yog hais txog lub peev xwm ntawm cov ntaub ntawv los nqus lub zog deformation thiab tiv thaiv kev puas tsuaj nyob rau hauv dynamic load, cuam tshuam load thiab alternating load. Nws yog ib qho kev qhia dav dav qhia txog qhov ductility thiab kev cuam tshuam ntawm cov ntaub ntawv.
Cov ntaub ntawv uas muaj zog toughness yuav tsim ib tug loj npaum li cas ntawm cov yas deformation ua ntej puas, uas yuav nqus tau sab nraud cuam tshuam lub zog thiab tsis txhob cia li nkig tawg. Ntawm qhov tsis sib xws, cov khoom siv tsis zoo yog qhov ua rau tawg sai sai yam tsis muaj qhov pom tseeb deformation, uas yog qhov txaus ntshai heev hauv cov qauv thauj khoom xws li steel txuas hniav thiab seismic Cheebtsam. Toughness daws qhov teeb meem ntawm"txawm tias cov khoom siv tiv thaiv kev cuam tshuam thiab kev puas tsuaj tam sim ntawd", thiab yog qhov tseem ceeb Performance index ntawm kev qaug zog thiab seismic kev ua tau zoo.
7. Rigidity
Rigidity yog ib qho khoom siv hluav taws xob sib txuam nrog kev hloov pauv yooj yim, piav qhia tag nrho cov tshuab hluav taws xob hauv lub xeev ntawm cov khoom nrog cov deformation me me hauv qab load. Nyob rau hauv cov tswv yim engineering, rigidity yog ib tug macroscopic structural yam ntxwv, thaum stiffness yog ib tug quantitative technical index.
Cov qauv nrog zoo rigidity muaj qhov ruaj khov tag nrho kev ntxhov siab, tsis muaj qhov pom tseeb deformation thiab muaj zog tiv thaiv - muaj peev xwm cuam tshuam. Nyob rau hauv lub tsev reinforcement thiab structural renovation tej yaam num, kev txhim kho structural rigidity yog lub hom phiaj tseem ceeb ntawm seismic reinforcement thiab stability optimization. Rigidity yog qhovmacro kev ua tau zoo ntawm siab tawv, tsom mus rau tag nrho lub xeev ruaj khov ntawm cov qauv.
8. Plasticity
Plasticity yog hais txog cov cuab yeej uas cov ntaub ntawv tsim cov deformation mus tas li irreversible deformation tom qab tshaj qhov elastic txwv thiab yuav tsis cia li rov qab los tom qab lub load raug tshem tawm. Yas deformation yog ib qho qeeb thiab ruaj khov deformation txheej txheem yam tsis muaj kev puas tsuaj tam sim ntawd.
Cov yas zoo heev ua rau cov hlau thiab cov pob zeb ua kom tsim cov deformation maj mam ua ntej tsis ua hauj lwm, tso cov txheej txheem sab hauv kev ntxhov siab, thiab tsis txhob poob ntawm tag nrho cov qauv. Vuam dabtsi yog khoov kuaj thiab cov ntaub ntawv tensile xeem yog ib qho tseem ceeb nrhiav kom tau txoj kev los xyuas kom meej cov khoom yas. Plasticity daws qhov teeb meem ntawm"txawm hais tias cov khoom yuav deform stably ua ntej tsis ua hauj lwm", uas yog tus yuam sij rau structural ductility thiab fault kam rau ua.
