Q: Dab tsi yog qhov ceev ntawm Q235 steel?
A: Kwv yees li 7.85 g / cm³, zoo ib yam nrog cov hlau zoo tib yam.
Q: Dab tsi yog qhov elastic modulus ntawm Q235 steel?
A: Kwv yees li 2.0 × 10⁵ MPa, feem ntau siv tus nqi hauv kev suav cov qauv engineering.
Q: Dab tsi yog Poisson tus piv ntawm Q235 steel?
A: Kwv yees li ntawm 0.3, qhov sib piv ntawm kev hloov pauv mus rau qhov ntev ntev thaum lub sij hawm elastic deformation.
Q: Dab tsi yog qhov tso cai deformation tus nqi rau Q235 steel Cheebtsam?
A: Raws li "Steel Structure Design Standard," piv txwv li, beam deflection Tsawg dua lossis sib npaug li L / 250 (L yog qhov ntev).
Q: Q235 steel puas tuaj yeem siv rau hauv seismic-cov qauv tiv thaiv?
A: Yog, nws yuav tsum ua kom tau raws li qhov yuav tsum tau ua rau seismic resistance; Qib B/D yog qhov nyiam.
