Lub ASTM W10x49 (W-puab) thiab GB HW 250x250 (dav-flange H-beam) yog qhov ua tau zoo piv rau nruab nrab-load daim ntawv thov tab sis txawv ntawm qhov loj me- xav tau kev hloov pauv hloov pauv:
Dimensional Breakdown (Metric Conversions)
| Dimension | ASTM W 10 x 49 | GB HW 250x250 (GB/T 11263) | Variance |
|---|---|---|---|
| Qhov tob (d) | 10.09 nti=256.3 hli | 250 hli | +6.3 hli |
| Flange dav (bf) | 8.00 nti=203.2 hli | 250 hli | -46.8 hli |
| Web Thickness (tw) | 0.345 nti=8.76 hli | 10 mm | -1.24 hli |
| Flange Thickness (tf) | 0.570 nti=14.48 hli | 13 hli | +1.48 hli |
| Qhov hnyav (w) | 49 lbs/ft=73.1 kg/m | 71.8 kg / m | +1.3 kg/m |
| Ntu Modulus (Sx) | 49.1 in³=805 cm³ | 8 12cm3 | - 7 cm³ |
Cov kev cuam tshuam rau kev hloov pauv
Haum: W10x49's nqaim flange (203.2 mm vs . 250 mm) txhais tau hais tias nws tsis tuaj yeem hloov HW 250x250 ncaj qha rau hauv cov hlua khi uas tsim los rau dav flanges. Txhawm rau daws qhov no, siv cov phaj adapter (10 hli tuab, 250 hli dav) kom phim GB bracket dav, kom ntseeg tau tias muaj kev sib cuag nrog W-puab lub flange.
Load Capacity: Cov seem modulus yog ze li qub (805 cm³ vs . 812 cm³), yog li khoov muaj peev xwm sib piv. A W10x49 A992 beam (345 MPa yield) txhawb ~ 278 kN·m (805 cm³ × 345 MPa), thaum HW 250x250 Q355B (355 MPa yield) txhawb ~ 288 kN·m-tsuas yog qhov sib txawv ntawm kev thauj khoom (1.3%).
Shear Capacity: W10x49's thinner web (8.76 mm vs . 10 mm) txo qhov peev xwm los ntawm ~ 12% (112 kN vs . 127 kN). Rau siab- daim ntawv thov shear (xws li, beam txhawb), ntxiv web stiffeners (100x10 mm daim hlau) ntawm 1-meter intervals kom tau raws li GB shear yuav tsum.
Txawm hais tias qhov sib txawv ntawm qhov sib txawv, W10x49 tuaj yeem hloov HW 250x250 nrog kev hloov kho me me, ua rau nws muaj peev xwm xaiv tau rau cov haujlwm uas muaj cov khoom siv tsawg GB.
