Yuav tsum muaj qhov tsawg tshaj plaws muaj zog rau A992 h - Beams?

ASTM A992 Mandates Tsawg Tshaj Plaws Lub Zog Ntawm 50 Ksi (345 MPa) Rau Txhua A992 H} Cov Khoom Siv Tseem Ceeb Los Ntawm 36 Ksi paib siv lub zog ntawm cov neeg siv A36. Cov txiaj ntsig tau hais txog qhov kev ntxhov siab tshaj plaws uas cov khoom siv tuaj yeem tiv thaiv tau ua ntej kev nyab xeeb rau kev tsim kho kev nyab xeeb hauv cov qauv txheej txheem qauv. Qhov txiaj ntsig zoo tshaj plaws lub zog tso cai rau cov engine los qhia cov khoom lag luam me, txo cov nqi, cov nqi siv nyiaj, thiab cov nqi thauj mus los. Txhawm rau kom ua raws li, cov chaw tsim khoom siv Tensile ntawm cov qauv coj tawm los ntawm txhua cov khoom lag luam ntau lawm. Thaum kuaj, tus qauv hnoos qeev tau rub kom txog thaum nws deforms plastically, nrog cov paib tau kaw cov ntaub ntawv thiab cov ntaub ntawv hauv cov ntawv pov thawj. Qhov 50 Ksi yam tsawg kawg yog tsis- muaj kev sib ceg; Ib qho batch tsis ua kom tau raws li qhov yuav tsum tau ua tiav qhov no tsis lees txais lossis rov hais dua. Qhov qauv nruj no kom ntseeg tau tias A992 h {19} Cov khoom siv (cov khoom siv sia), thiab cov khoom siv uas tuag taus ntawm cov tsev thiab cov teeb meem.
