Ib leeg lub zog muaj zog tuav lub steel bar nyob rau hauv qhov nro, tab sis nyob rau hauv ob npaug ntxiv cov kab teeb, steel tuav yog muab rau hauv ob qho tib si, nro, thiab compressionHauv singly reinforced beam compression, kev ntxhov siab resists los ntawm cov pob zeb, thaum nyob rau hauv doubly reinforced beam compression steel, counters compression stress.
Yuav ua li cas thiaj txhawb nqa lub suab?
Lub nqaj uas yog longitudinally reinforced tsuas yog nyob rau hauv nro zone, nws yog hu ua singly reinforced beam. Nyob rau hauv xws li kab teeb, qhov kawg khoov lub sij hawm thiab qhov nro vim yog dabtsi yog khoov yog nqa los ntawm lub reinforcement, thaum lub compression yog nqa los ntawm cov pob zeb.
Yuav ua li cas yog ob npaug ntxiv beam?
Xws li pob zeb ua vaj huam sib luag muaj cov hlau reinforcement ob leeg ntawm lub ntsej muag tensile thiab compressiveyog lub npe hu ua ob npaug ntxiv cov kab teeb. Doubly reinforced beams, yog li ntawd, muaj lub sij hawm ntawm kev tiv thaiv ntau tshaj cov singly reinforced beams ntawm tib qhov tob rau tej qib ntawm steel thiab pob zeb.
Vim li cas thiaj nyiam dua ob npaug?
Muab ob npaug ntxiv cov seem yog siv nyob rau hauv cov xwm txheej hauv qab no: Thaum qhov ntev (b x d) ntawm lub nqaj raug txwv vim muaj kev txwvzoo li muaj chav hauv taub hau, kev tsim vaj tsev lossis chaw xav txog thiab lub sijhawm ntawm kev tawm tsam ntawm singly reinforced seem yog tsawg dua lub sijhawm sab nraud.
Dab tsi yog qhov zoo ntawm ob npaug ntxiv beam tshaj singly reinforced beam?
Lub sijhawm ntawm kev tiv thaiv tsis tuaj yeem nce ntxivtus nqi ntawm cov hlau hauv qhov nro. Nws tuaj yeem nce ntxiv los ntawm kev ua kom lub nqaj hla lub zog tab sis tsis pub ntau tshaj 25% ntawm sab strained. Yog li ob npaug ntxiv beam yog muab los ua kom lub sij hawm ntawm kev ua hauj lwm ntawm ib tug nqaj muaj qhov ntev.

Qhov txawv ntawm qhov txuas mus ntxiv thiab txuas ntxiv yog dab tsi?
Continual yuav tsum tsuas yog txhais tau tias " tshwm sim ntawm qhov tsis tu ncua," lawv hais, qhov txuas ntxiv yuav tsum tau siv los txhais " txuas ntxiv yam tsis muaj kev cuam tshuam " Qhov kev sib txawv no overlooks qhov tseeb tias txuas ntxiv yog lo lus laus thiab tau siv nrog ob lub ntsiab lus rau ntau pua xyoo ua ntej txuas ntxiv tshwm sim ntawm qhov chaw .
