2 zvikumbiro zvakati zvegirazi fiber

2.1 kusimbisa nheyo yegirazi fiber yakasimbiswa kongiri

Iyo nheyo yegirazi fiber yakasimbiswa kongiri yakafanana kwazvo neiyo yegirazi fiber yakasimbiswa yakasimbiswa. Chekutanga pane zvese, kuwedzera girazi fiber kune kongiri, iyo girazi fiber ichatakura kushushikana kwemukati kwechinyorwa, kuitira kunonoka kana kudzivirira kuwedzera kwemicro-matsvuku. Munguva yekuumbwa kweakangoita concrete marara, zvinyorwa zvinoita sekuunganidzwa zvichadzivirira kuitika kwemaza. Kana iyo yakaunganidzwa mhedzisiro yakakwana zvakakwana, marara haazokwanisi kuwedzera uye kupinda. Basa regirazi fiber mukongiri iri kuunganidzwa, iyo inogona kudzivirira zvinobudirira chizvarwa uye kuwedzera kwemazamu. Kana kupenga kuchaparadzira kune iyo yegirazi fiber, girazi fiber richavharira kufambira mberi kwekupenga, nekudaro vachimanikidza kupenga kuti vatore madhiri, uye inoenderana, iyo nzvimbo yekuwedzera yekukasira ichawedzerwa, saka simba rinodiwa kukuvara kuchawedzerawo.

2.2 Kuparadza mechanism yegirazi fiber yakasimbiswa kongiri

Pamberi pegirazi fiber yakasimbisa kongiri, iyo inonsle simba inobereka inonyanya kugoverwa nekongiri uye girazi fiber. Munguva yekupaza, kushushikana kuchafambiswa kubva kukongiri kune yepedyo girazi fiber. Kana simba rakasimba racho richiramba richikura, iyo girazi fiber ichakanganisika, uye nzira dzekukuvadza dziri kunyanya kubhururuka kukuvara, kusanzwisisika kukuvara, uye kukuvadza-kukuvadza.

2.2.1 Shear Kutadza

Iko kushungurudzika kweshekeri kwakarambidzwa negirazi yakasimbiswa nekongiri yakagoverwa negirazi Nekudaro, girazi fiber rine zvayo zvakanakira. Iyo ine urefu hwakareba uye nzvimbo diki yekushambadzira, saka kuvandudzwa kwemasheya ekuramba kwegirazi fiber haina kusimba.

2.2.2 kushushikana kwekutadza

Kana simba remafuta egirazi rakakura kupfuura rimwe danho, girazi fiber richazotyora. Kana iyo kongiri yemakona, girazi fiber ichave yakareba kureba nekuda kweiyo tensile deformation, iyo yakawanda yakawanda ruzha ruchanonoka, uye simba resimba rinokurumidza kuputsa nekukurumidza.

2.2.3 Dhonza-kubvisa kukuvara

Kamwe chete kupaza kongiri, simba regirazi regirazi richavandudzwa zvikuru, uye simba remanyorero richava rakakura kupfuura simba regirazi uye kongiri, kuti girazi fiber richakuvara uye rinobva raburitswa.

2.3 Zvinosindimara zvivakwa zvegirazi fiber yakasimbiswa kongiri

Kana iyo yakasimbiswa kongiri ichitakura mutoro, kunetseka kwayo-strain curve kuchakamurwa kuita matanho matatu akasiyana kubva mukunyorwa kwekunyora, sezvakaratidzwa muhuwandu. Chikamu chekutanga: Elastic deformurs kutanga kusvika yekutanga kupaza kunoitika. Chinhu chikuru chechikamu ichi ndechekuti iyo deformation inowedzera mutsara kusvika pakona iyo, iyo inomiririra yekutanga kupaza simba regirazi rakasimbiswa kongiri. Nhanho yechipiri: Kamwe chete congm concrete, iyo inotakura ichatenderwa kune iyo yepedyo fibers kutakura, uye kugona kwakatarwa kwakatemwa maererano negirazi fiber pachayo uye simba rekusungwa nekongiri. Pfungwa B ndiyo yekupedzisira inoshandiswa simba regirazi fiber rakasimbiswa kongiri. Nhanho yechitatu: Kusvikira Simba rekupedzisira, iyo yegirazi fiber inoputsa kana kudhonzwa, uye iyo masisitimu asara anogona kutakura chikamu chemutoro kuti ave nechokwadi chekuti bracttle harizoitika.
