Intsimbi yentsimbi, nokuba iqhelekile okanye ilula, inobukhulu obunqamlezileyo obuphezulu kwaye bumxinwa, ngoko ke umzuzu we-inertia yeentsimbi ezimbini eziphambili zecandelo lomnqamlezo wahluke kakhulu, ngoko unokusetyenziswa ngokuthe ngqo kumalungu agobileyo. inqwelomoya yepleyiti yayo yewebhu okanye yenziwe ngamalungu anelatyisi.Ayifanelekanga kumalungu e-axial compression okanye amalungu agobileyo kwi-plane perpendicular to the web, ethintela isicelo sabo.
steel i beam ubukhulu becala zahlulwe intsimbi eqhelekileyo i beam, ukukhanya intsimbi i umqadi kunye nentsimbi flange ububanzi i beam.intsimbi i beam kunye flanges ebanzi, iiflanges eliphakathi kunye flanges emxinwa zahlulwe ngokomlinganiselo ukuphakama flanges ukuba webs.Iimpawu ezimbini zangaphambili ziyi-10-60, oko kukuthi, ukuphakama okuhambelanayo ngu-10 cm-60 cm.Kubude obufanayo, intsimbi ekhanyayo i-i beam ineflange emxinwa, iwebhu encinci kunye nobunzima obulula.intsimbi i beam nge flange ebanzi, eyaziwa ngokuba yintsimbi H umqadi, luphawulwa ngemilenze parallel kwaye akukho kuthambekela ngaphakathi imilenze.Iyeyentsimbi yecandelo loqoqosho kwaye iqengqeleke kwi-four-high universal rolling mill, ngoko ikwabizwa ngokuba yi "universal steel i beam".
