Masimbi anopisa anokungurutswa simbi dzakapedzwa simbi 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 neimwe 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-yakakungurutswa simbi bhaa yakapfava uye yakaoma, uye ichava neineck phenomenon kana ichiputsika, uye elongation mwero wakakura.
