Engineered kuv-beam

Ib qho I-beam yog ib kab qauv nrog tus ntoo khaub lig-sectional duab zoo li tsab ntawv "I," uas muaj lub flange sab saum toj, lub flange qis rau hauv qab, thiab lub vev xaib txuas ob. Raws li seb cov flange widths sib npaug, kuv- kab teeb tuaj yeem muab faib ua qhov sib npaug -flange I-beams lossis tsis sib npaug-flange I-beams (qhov twg lub sab sauv thiab qis flange dav sib txawv).

Los ntawm kev faib cov khoom siv, kuv- kab teeb feem ntau suav nrog cov kab hlau, cov kab hluav taws xob ntxiv, thiab cov kab hluav taws xob prestressed reinforced beams. Qhov kev tsim no ua rau muaj peev xwm khoov los ntawm kev ua kom thaj tsam flange thaum txhim kho cov khoom faib, txo cov khoom siv los ntawm 15% -20%.

Lub hauv paus ntsiab lus ntawm I-beams yog raws li kev cuam tshuam ntawm tus ntoo khaub lig-sectional puab ntawm dabtsi yog khoov nruj: nyob rau hauv khoov, lub sab sauv flange muaj kev nyuaj siab compressive thaum lub qis flange undergoes tensile kev nyuaj siab, nrog tsawg heev kev nyuaj siab nyob ze ntawm lub nruab nrab txheej. Concentrating cov ntaub ntawv nyob rau hauv lub flanges - deb ntawm qhov nruab nrab axis - ua kom tau zoo rau ntu ntu thib ob ntawm thaj chaw (lub sijhawm ntawm inertia), yog li txhim kho khoov tsis kam thiab txuag cov khoom.

Hauv cov ntawv thov engineering, I- kab teeb yog siv dav hauv cov choj thiab cov qauv hauv tsev. Muab piv rau cov slab txuas hniav, lawv muaj qhov sib zog ntawm tus kheej- hnyav thiab ua kom haum rau qhov loj dua (feem ntau 20-}50 meters), txawm hais tias kev sib txuas rau sab nraud yuav tsum tau ua kom muaj kev ncaj ncees. Hauv kev tsim vaj tsev, lawv cov khoom siv tau zoo ua rau lawv muaj cov khoom siv thauj khoom.
