Lonke uchungechunge lwentambo ngokwezifiso

Ibanga lokusebenza kwebhawodi lakhiwe izingxenye ezimbili zezinombolo, ezimele ngokulandelana amandla aqine we-bolt kanye nesilinganiso sesivuno sokwaziswa. Isibonelo, okushiwo amabhawodi anebanga lokusebenza lika-4.6 yile: inombolo engxenyeni yokuqala (4 ku-4.6) ingu-1/100 yamandla aqine okuqina (n / mm2) wezinto ezisisibopho, okungukuthi, uFu ≥ 400N / mm2; Inombolo engxenyeni yesibili (6 ku-4.6) iyizikhathi eziyi-10 zesilinganiso sesivuno sezinto ezisekelweni, okungukuthi, FY / Fu = 0.6; Umkhiqizo wezinombolo ezimbili (4) × 6 = "24") ngu-1/10 wendawo yokuqokwa (noma amandla wokukhiqiza) (n / mm2) wento yensimbi, okungukuthi, FY ≥ 240n / mm2.

Ngokuya ngokunemba kokukhiqiza, imishudo ejwayelekile yensimbi ingahlukaniswa ngezigaba ezintathu: I-A, B ne-CA Ibanga B yibholidi elicwengekile, elisetshenziselwa imikhiqizo yomshini, kanti ibanga C liyisigaxa esibi. Ngaphandle kokuthi kuchazwe ngenye indlela, amabhawodi ajwayelekile esakhiwo sensimbi imvamisa imishudo ejwayelekile C ebanzi C enebanga lokusebenza lika-4.6 noma 4.8.
