Kev sib piv ntawm qhov zoo thiab qhov tsis zoo ntawm kev siv cov square tube, channel steel, lub kaum sab xis steel

Qhov zoo ntawmcev square
Siab compressive zog, zoo dabtsi yog khoov zog, siab torsional zog, zoo stability ntawm seem loj.
Vuam, kev sib txuas, kev ua haujlwm yooj yim, zoo plasticity, txias khoov, txias dov kev ua haujlwm.
Loj cheeb tsam, tsawg steel ib chav tsev saum npoo av, txuag steel.
Surrounding prongs tuaj yeem txhim kho lub peev xwm ntawm cov tswv cuab.

Qhov tsis zoo
Theoretical hnyav yog loj dua channel steel, tus nqi siab.
Tsuas yog tsim nyog rau cov qauv nrog siab dabtsi yog khoov lub zog xav tau.

Qhov zoo ntawmChannel steel
Siab dua dabtsi yog khoov thiab torsional lub zog, haum rau cov qauv raug rau siab dua dabtsi yog khoov thiab torsional moments.
Me me hla ntu me me, sib dua qhov hnyav, txuag steel.
Zoo shear tsis kam, tuaj yeem siv rau cov qauv uas muaj zog shear loj.
Kev siv tshuab yooj yim, tus nqi qis.

Qhov tsis zoo
Tsawg compressive zog, tsuas yog haum rau cov qauv raug khoov lossis torsion.
Vim qhov tsis sib xws ntawm ntu, nws yooj yim los tsim cov buckling hauv zos thaum raug kev kub ntxhov.

Qhov zoo ntawmLub kaum sab xis
Tej yam yooj yim cross-sectional zoo, yooj yim rau fabricate, uas tsis muaj nqi.
Nws muaj qhov zoo ntawm kev khoov thiab torsion tsis kam thiab tsim nyog rau cov qauv uas raug khoov loj thiab torsion lub sijhawm.
Yuav siv tau los ua ntau yam thav duab thiab braces.

Qhov tsis zoo
Tsawg compressive zog, tsuas yog siv rau cov qauv uas yuav khoov lossis torsion.
Vim qhov tsis sib xws ntawm ntu, nws yooj yim los tsim cov buckling hauv zos thaum raug compression.

Square raj, u channel thiab lub kaum sab xis bar muaj lawv tus kheej zoo thiab qhov tsis zoo, thiab yuav tsum tau xaiv raws li daim ntawv thov tiag tiag.
Nyob rau hauv cov ntaub ntawv ntawm qhov yuav tsum tau tiv thaiv loj compressive kev nyuaj siab, square tube yog ib tug zoo xaiv.
Nyob rau hauv cov ntaub ntawv ntawm loj dabtsi yog khoov los yog torsion rog, raws thiab cov ces kaum yog ib tug zoo xaiv.
Nyob rau hauv rooj plaub uas yuav tsum tau xav txog tus nqi thiab kev siv tshuab, channel steel thiab lub kaum sab xis steel yog qhov kev xaiv zoo dua.
