Masimbi anopisa akakungurutswa simbi dzakapedzwa dzakaputirwa nekudziya uye dzakatonhodzwa zvechisikigo.Iwo akagadzirwa neakaderera-kabhoni simbi uye yakajairwa alloy simbi pakupisa kwakanyanya.Iwo anonyanya kushandiswa pakusimbisa kongiri yakasimbiswa uye prestressed kongiri zvimiro.Imwe yemhando dzakanyanya kushandiswa dzesimbi.
Kupisa-yakaputirwa simbi mbariro dzesimbi dzine hupamhi hwe 6.5-9 mm, uye dzakawanda dzadzo dzakaputirwa mumatanda etambo;idzo dzine dhayamita 10-40 mm dzinowanzoita mbariro dzakatwasuka dzine kureba kwemamita 6-12.Kupisa-akakungurutswa simbi mbariro dzinofanira kuva imwe simba, kureva goho poindi uye tensile simba, ari hwaro chikuru dhizaini dhizaini.Yakakamurwa kuva mhando mbiri: inopisa-yakakungurutswa yakapoteredza simbi bar uye inopisa-yakakungurutswa ribbed simbi simbi.Iyo inopisa-yakatenderedzwa simbi bhaa yakapfava uye yakaoma, uye ichava neineck phenomenon kana ichiputsika, uye elongation mwero wakakura.
