ʻO ka lintel angle kila ka weldability maikaʻi, ka hana deformation plastic a me kekahi ikaika mechanical e koi ʻia i ka hoʻohana.E like me nā pono like ʻole o ka hale, hiki ke hoʻokumu ʻia nā lālā koʻikoʻi like ʻole, a hiki ke hoʻohana ʻia i mea hoʻohui ma waena o nā lālā.

Ua kuhikuhi ʻia ka maikaʻi o ka ʻili o ka pahu kihi kila i ka maʻamau, a koi ʻia ʻaʻole pono nā hemahema i ka hoʻohana ʻana, e like me ka delamination, scarring, māwae, etc.

ʻO ka ʻae ʻia o ka ʻae ʻia ʻana o ka geometry deviation steel angle bar geometry deviation i loko o ka maʻamau, ʻo ia hoʻi nā mea e like me ke degere bending, ākea ʻaoʻao, ʻaoʻao mānoanoa, vertex angle, theoretical weight, etc., a ua ʻōlelo ʻia ʻaʻole pono ke kila kihi. loaʻa i ka torsion nui.
