Round steel beam yog ib hom kaw -section structural steel. Lawv feem ntau yog tsim los ntawm dov thiab vuam steel daim hlau los yog los ntawm ib qho kev tsim khoom xws li kub- dov lossis txias - kos duab.
Lawv cov lus qhia tshwj xeeb yog feem ntau qhia los ntawm sab nraud (D) × phab ntsa thickness (t).
Qhov tseem ceeb zoo thiab yam ntxwv
Round steel beam peb tsim muaj cov khoom zoo tshaj plaws isotropic thiab tsis sib haum torsional kuj. Lawv kuj muab qhov zoo tshaj plaws compressive zog thiab cov dej zoo dynamic yam ntxwv, nrog rau kev zoo nkauj zoo nkauj.
Txawm li cas los xij, nws tseem ceeb heev kom nkag siab txog lawv cov kev txwv. Ib qho teeb meem tseem ceeb thaum siv lub voj voog ncig raws li cov tswv cuab nqa cov khoom ntsug yog nws cov txheeb ze inefficiency hauv dabtsi yog khoov. Vim tias cov khoom sib npaug sib npaug ntawm nws qhov chaw, ib feem tseem ceeb nyob ze ntawm qhov nruab nrab axis. Cov khoom no pab txhawb me ntsis rau tiv thaiv lub sijhawm khoov. Yog li ntawd, ib qho kev voj voog feem ntau yuav tsum muaj qhov loj dua, kev lag luam tsawg dua -section piv rau H-beam ntawm qhov hnyav sib npaug los txhawb tib lub bending load.
Thawj Daim Ntawv Thov Scenarios
Nyob rau hauv peb lub tuam txhab, ncig steel beams feem ntau teev rau:
Cheebtsam raug rau qhov tseem ceeb torsion.
Offshore platforms thiab chaw nres nkoj engineering qauv.
Public architecture thiab qhov chaw thav duab.
Lub voj voos hlau yog ib tus tswv cuab tshwj xeeb hauv cov qauv- cov khoom siv tshwj xeeb tiag tiag nrog qhov zoo tshwj xeeb rau cov kev sib tw tshwj xeeb.
