(1) Iyo node yekubatanidza inokodzera kuchinjisa yakananga, uye haidi kupfuura nepane node ndiro kana zvimwe zvikamu zvekubatanidza, izvo zvinoponesa basa uye zvinhu.

(2) Kana zvichidiwa, kongiri inogona kudururwa mupombi kuti iite chikamu chinoumbwa.

(3) Mamiriro ejometri echikamu chepombi akanaka, madziro epombi anowanzo kutetepa, zvinhu zvechikamu zvinogoverwa kutenderedza centroid, radius ye gyration yechikamu yakakura, uye ine yakasimba torsional rigidity;sekudzvanyirira, kudzvanya, uye bidirectional bending component, yayo Iyo Kutakura kugona kwakakwira, uye kutwasanuka kwemapombi anotonhora-akaumbwa uye kurongeka kwemhiri-sectional dimensions zviri nani pane izvo zvinopisa-yakakungurutswa yakavhurika yakavhurika-zvikamu.

(4) Chitarisiko chakanyanya kunaka, kunyanya iyo pombi truss inoumbwa nesimbi pombi nhengo, hapana mubatanidzwa wakawedzera kubatana, uye kunzwa kwemazuva ano kwakasimba.

(5) Mukutaura kwemaitiro e-anti-hydrodynamic, chikamu chemuchinjikwa wechubhu inotenderera iri nani, uye mhedzisiro yemhepo nemvura inoyerera inoderedzwa zvakanyanya.Rectangular chubhu chikamu chakafanana nezvimwe zvikamu zvakavhurika mune izvi.

(6) Mapaipi esimbi ane dhayamita mahombe akavhara machinjiro;apo avhareji ukobvu uye mhiri-chikamu nzvimbo yakafanana, nzvimbo yakazaruka inosvika 50% kusvika 60% yemuchinjiko wakavhurika, uyo unobatsira kudzivirira ngura uye inogona kuchengetedza zvinhu zvekupfeka.
