Hauv RCC stairs lub slab nws tus kheej ua raws li nqaj txhawb nqa loads yam tsis muaj dabtsi yog khoov. Nyob rau hauv steel stairs cov loads ntawm cov kauj ruam yuav tsum tau muab xa mus rau ib tug nqaj tsis muaj difflection. Qhov no nqaj tsis yog kab rov tav. Nws yog cranked nrog anangle rau kab rov tav. Li no nws thiaj hu ua crankedbeam.
Ib yam li ntawd, vim li cas crank muab nyob rau hauv beam?
Cov crank bar lossis bent up bar yog qhov tseem ceeb heev hauv R. C. C nqaj los yog slabs kev tsim kho vim hais tias tsis muaj kev cuam tshuam lub Hogging (tsis zoo lub sij hawm) tus qauv yuav ua tsis tau tejyam orthe lub zog ntawm cov qauv yuav txo. Lub hogging bendingmoment yuav txhim kho ntawm kev txhawb nqa ntawm slabs thiab kab teeb.
Tsis tas li ntawd, crank civil engineering yog dab tsi? Crank yog me ntsis dabtsi yog khoov nyob rau hauv tuav ntawm lub puab tsaig sothat tuav lub meej npog txawm nyob rau hauv lub puab tsaig txoj hauj lwm. Txoj cai uas feem ntau siv yog tias txoj kab nqes ntawm crank 1:10 & yam tsawg kawg nkaus ntev ntawm crank 300 hli. Crank ntev ntawm kev txhawb zog.
Tsis tas li cov lus nug yog, vim li cas cov pas tuav cranked?
Ib bent-up bar npe as crank bar yog muab los ua RCC slab muaj kev nyab xeeb los ntawm kev ntxhov siab. Thaum bentup tuav yog muab, lub zog thiab deformation muaj peev xwm ntawm slabs nrog khoov tuav piv rau slabs tsis khoov tuav yog txaus nce. 2. Los tiv thaiv shear force uas yog ntau dua ntawm kev txhawb nqa.
Dab tsi yog bent up bar hauv beam?
Khoov bar muaj nyob rau hauv a nqaj thiaj li tiv tus Negative Khoov Moment generated atsupports. Hauv qab no yog BMD ntawm kev txuas ntxiv Beam : Nyob ntawm qhov tsis zoo Khoov Lub sijhawm nro yog nyob rau sab saum toj ntawm Slab yog li yuav tsum muaj kev txhawb zog rau sab saum toj ntawm Slab.

Dab tsi yog shear force hauv beam?
Shear force yog lub zog nyob rau hauv lub beam ua perpendicular rau nws longitudinal (x) axis. Lub hom phiaj Fordesign, nqaj lub peev xwm los tiv thaiv shearforce yog qhov tseem ceeb tshaj li nws lub peev xwm los tawm tsam lub zog. Lub zog shear ntawm qhov kawg ntawm lub beam yog sib npaug rau lub zog ntsug ntawm kev txhawb nqa
Dab tsi yog footing tie beam?

Dab tsi yog qhov txawv ntawm qhov I beam thiab H beam?
Nws tau txais nws lub npe vim tias nws zoo li lub peev H hla nws ntu ntu. H-beam muaj qhov dav dav dua li I-beam, tab sis I-beam muaj taperededges. Qhov dav yog qhov flange, thiab qhov siab yog Web. Qhov sib txawv ntawm ob qho tib si H-beams thiab I-beams yog flange los ntawm lub vev xaib sib piv
Dab tsi yog channel beam?
Cov txheej txheem channel, tseem hu ua aC-channel lossis Parallel Flange Channel (PFC), yog hom (feem ntau yog cov qauv hlau) nqaj, siv feem ntau hauv kev tsim kho thiab kev tsim vaj tsev hauv vaj tse
