Makalasi ndi zinthu zogwiritsiridwa ntchito kwa mitu yolumikizirana yamakina

Analimbitsa mawotchi kugwirizana mutu molingana ndi mfundo kamangidwe anawagawaⅠ, Ⅱ, Ⅲpamiyezo itatu.Malumikizidwewo adzakhala amphamvu ndi mapindikidwe.Zomwe zimapangidwira zokolola ndi mphamvu zowonongeka zamagulu sizikhala zosachepera 1.10 nthawi zamtengo wapatali za zokolola ndi mphamvu zowonongeka za kulimbikitsana kolumikizidwa.Malinga ndi kalasi yake ndi ntchito, olowa adzazindikira lolingana anayendera zinthu zosiyanasiyana katundu monga unidirectional kumakoka ntchito, mkulu kupsyinjika mobwerezabwereza kukankha, mapindikidwe lalikulu mobwerezabwereza kukankha, kukana kutopa ndi otsika kutentha kukana.

Malingana ndi kusiyana kwa mphamvu zolimba, kubwereza mobwerezabwereza komanso kupanikizika pansi pa kupsinjika kwakukulu ndi kupunduka kwakukulu, magulu a mafupa ndi osiyana:

Ⅰ, olowa amakokedwe mphamvu zosachepera kulumikizika zitsulo amakokedwe mphamvu zenizeni kapena 1.10 nthawi chitsulo kumakokedwe mphamvu muyezo makhalidwe, ndipo ali ductility mkulu ndi mobwerezabwereza kukangana ndi psinjika ntchito.

Ⅱ, mphamvu yamakomedwe olowa sipang'ono poyerekeza ndi miyeso yolumikizidwa yachitsulo cholumikizira mphamvu, ndipo imakhala ndi ductility yayikulu komanso kukakamiza kobwerezabwereza komanso kukakamiza.

Ⅲ, olowa amakokedwe mphamvu si zosakwana 1.35 nthawi olumikizidwa zitsulo zokolola mphamvu muyezo makhalidwe, ndipo ali ductility ena ndi mobwerezabwereza mavuto ndi psinjika ntchito.

Kugwiritsa ntchito zolumikizira zolimbitsa thupi:

Kufunsidwa perekani sewero lathunthu ku mphamvu ya zomangira zolimba za konkriti kapena mbali zolumikizirana kuti zifune milingo yayikulu pogwiritsa ntchitoⅠ or Ⅱmgwirizano;

Zomangamanga zolimba za konkriti zomwe zimagwiritsidwa ntchito zimakakamiza kufunikira kwapamwamba kwa ductility sikukwera koma kwa magawo olowa, kutengeraⅢzolumikizira.
