I-beam tuaj yeem muab faib ua ntau hom khoom raws li qhov sib txawv flange ntawm I-beam, thiab lawv cov ntawv thov kuj txawv. Txawm hais tias nws yog qhov zoo tib yam los yog lub teeb yuag, vim yog qhov siab thiab nqaim cross-sectional dimensions, muaj qhov sib txawv tseem ceeb hauv lub sijhawm inertia ntawm ob lub tsho tseem ceeb ntawm tus ntoo khaub lig-section. Yog li ntawd, feem ntau nws tsuas yog siv ncaj qha rau cov khoom uas yog khoov rau hauv nws lub vev xaib dav hlau lossis tsim cov lattice load-cov kabmob. Cov khoom siv kho tshuab ntawm I-beams raug tshuaj xyuas ntawm lub Hoobkas, yog li kev soj ntsuam kev ua tau zoo suav nrog dab tsi?
Txoj kev soj ntsuam kev ua tau zoo ntawm I-beam yog feem ntau Tensile xeem thiab dabtsi yog khoov xeem, uas feem ntau yog hais txog cov khoom tshuaj ntsuam xyuas kev ua tau zoo ntawm lub kaum sab xis steel, thiab cov ntsuas muaj xws li yield point, tensile zog, elongation thiab dabtsi yog khoov. Cov kev tshuaj ntsuam hauv qab no feem ntau suav nrog:
1. Tensile xeem: cov qauv kev soj ntsuam zoo xws li GB/T228-87, JISZ2201, JISZ2241, ASTMA370 ГОСТ 1497, BS18, DIN50145, thiab lwm yam;
2. Kev xeem dabtsi yog khoov: Feem ntau siv cov qauv tshuaj ntsuam xyuas xws li GB/T232-88, JISZ2204, JISZ2248, ASTME290 ГОСТ 14019, DIN50111, thiab lwm yam;
Hauv cov ntsiab lus, ob txoj hauv kev saum toj no feem ntau yog siv rau kev soj ntsuam kev ua haujlwm ntawm I- kab teeb los xyuas seb lawv lub zog tensile, elongation, dabtsi yog khoov, thiab lwm yam. I-beams tuaj yeem siv los ua ntau yam kev thauj khoom-cov kabmob raws li qhov xav tau ntawm cov qauv sib txawv, thiab tseem tuaj yeem siv los ua cov khoom sib txuas ntawm cov khoom, dav siv hauv ntau lub tsev thiab engineering.
