Vim li cas I-Beam Stronger dua ib lub Beam Solid?
Thaum koj xav txog lub cev ntawm cov hlau, nws tsis xav tsis thoob tias nws yog cov hlau siv ntau tshaj plaws hauv kev tsim kho tshiab niaj hnub no. Hlau tuaj yeem tiv taus cov ntsiab lus, dais qhov hnyav hnyav, thiab yog qhov zoo nkauj heev.
Vim li cas nws tseem ceeb uas steel yog yooj yim rau sculpt? Nws tso cai rau cov tuam txhab tsim ntau yam steel beam styles thiab cov duab rau ntau yam kev tsim kho.
Nyob rau saum npoo, tej zaum koj yuav xav tias lub teeb steel hlau yuav yog qhov kev xaiv muaj zog tshaj plaws. Qhov tseeb yog tias i-beam lub zog muaj zog ntau dua, tshwj xeeb tshaj yog thaum koj xav tias tib lub hlaws tuaj yeem nqa tau hnyav dua thaum sculpted rau hauv "Kuv" zoo li.
Npaj los kawm ntxiv txog i-beam lub zog thiab vim li cas i-beams ua tau zoo dua cov kab teeb? Nyeem ntxiv kom paub.
I-Beam Strength tsim txawm tias qhov hnyav faib
Raws li peb tau hais ua ntej, i-beams tau txais lawv lub npe vim lawv "Kuv" zoo li. Lub flange yog qhov dav dua li lub vev xaib, uas hloov txoj hauv kev uas tag nrho cov nqaj faib qhov hnyav.
Thaum qhov hnyav yog siv rau lub flange, lub flange tuav qhov hnyav ntawm ib sab mus rau lwm qhov, txo qhov nro ntawm lub vev xaib. Thaum lub sij hawm qhov nro mus txog qhov nruab nrab axis (qhov nruab nrab ntawm lub vev xaib), qhov nro yog txo kom tsis muaj dab tsi. Ua tsaug rau qhov no txawm tias qhov hnyav faib tsim los ntawm i-beam lub "Kuv" zoo, nws tuaj yeem dais qhov hnyav siv rau lub flange.
Siab Load-Bearing Capacity
Xav txog ib qho i-beam thiab ib lub beam khoom nrog tib ntu ntu. Vim hais tias ib qho i-beam yog dov rau hauv qhov "Kuv" zoo li, lub i-beam yuav muaj ntau dua flange deg cheeb tsam tshaj li ib tug khoom beam. Rau tib tus nqi ntawm cov hlau siv thiab tib qhov hnyav tag nrho, koj yuav tau txais lub peev xwm load-bearing ntau dua thiab lub sijhawm siab ntawm inertia nrog i-beam vim nws lub peev xwm los faib qhov hnyav ntawd.
I-beams kuj muaj lub peev xwm thauj khoom siab vim tias lawv yuav khoov nyob rau hauv kev ntxhov siab, tsis yog buckle. Kev khoov yog qhov zoo dua vim tias lub beam dabtsi yog khoov txhawb nqa lwm tus tswvcuab, es tsis ua kom nruj ntxiv rau lawv. Raws li qhov tshwm sim, i-beams txo qhov xav tau rau ob peb yam khoom siv ntxiv thiab kev txhawb nqa cov qauv uas yuav tsum tau ua kom muaj kev sib zog ntxiv los ntawm buckling.
