E like me kā kākou e ʻike nei,ʻāpana hakahaka kilahe mea hana hale maʻamau no nā hale kila. Ua ʻike anei ʻoe i ka nui o nā ʻano ʻāpana o nā lālā hale kila kiʻekiʻe? E nānā kākou i kēia lā.
1, lālā i hoʻokaumaha ʻia ma ke axial
ʻO ka lālā e hali ana i ka ikaika axial e pili ana i ka tension axial o ka lālā e hali ana i ka tension axial a i ʻole ke kaomi axial, ʻo ia ka mea maʻalahi loa i waena o nā lālā.
2, lālā Flexural
Hoʻopilikia nui ʻia nā lālā kūlou i nā manawa kūlou a me nā ikaika transverse, ʻo ka hapa nui o ia mau mea he mau kaola. ʻO ke ʻano mahele maʻamau o kēia lālā he ʻano I. Aia pū kekahi groove, trapezoid a me ke ʻano Z ke liʻiliʻi ka ikaika. Ke nui ka ikaika, hiki ke hoʻohana ʻia ke ʻano pahu. Pono e hoʻomaopopo ʻia i ka wā e helu ai i ka ikaika kūkulu o ia mau lālā, ʻaʻole wale ka ikaika kūlou, akā, ʻo ka ikaika shear a me ke kūpaʻa hoʻi e helu ʻia.
3, Lālā i hoʻouka ʻia me ke ʻano ʻē
ʻO nā lālā i hoʻokaumaha ʻia eccentrically ma ke ʻano laulā, ʻaʻole wale ka ʻeha o ka ikaika axial, akā, mai ka manawa kūlou a me ka ikaika ʻoki transverse. ʻO nā lālā i hoʻokaumaha ʻia eccentrically ma ke ʻano laulā he ʻelua ʻano o nā ʻāpana ʻano keʻa a me ke ʻano I. Ke nui ka ukana, hiki ke hoʻohana ʻia nā lālā tubular a me nā ʻano pahu. He nui nā ʻano ʻāpana o nā lālā i hoʻouka ʻia eccentrically, a ʻoi aku ka paʻakikī o ka helu ʻana ma mua o nā lālā mua ʻelua, ʻo ia hoʻi, e helu i ka ikaika, akā e nānā pū i ke kūpaʻa.
ʻO nā ʻāpana nui o nā hale kila kiʻekiʻe, ʻo ia nā kaola a me nā kolamu. ʻIke loa, ʻokoʻa loa nā ʻano ʻāpana o nā kaola a me nā kolamu, a he nui nā ʻano like ʻole. ʻOiai ʻokoʻa loa nā ʻano o nā ʻāpana, ua like lākou i nā loina hoʻolālā. Ua kaupalena ʻia ke ʻano ʻāpana kea o ka kaola i ke ʻano I a me ke ʻano pahu. Hiki ke hoʻokaʻawale ʻia ke ʻano ʻāpana kea o ke kolamu i ʻelua mau ʻāpana, ʻo kekahi he ʻāpana paʻa, ʻo ia hoʻi ke ʻano I a me ke ʻano kea. ʻO kekahi he ʻāpana hakahaka, ʻo ia hoʻi ke ʻano tubular a me ka pahu.
Mai ka manaʻo hana ʻana, i kekahi mau hihia, ʻaʻole hiki i nā lālā i hana ʻia me kahi hale kila hoʻokahi ke hoʻokō i nā koi hoʻolālā. No laila, pono e hoʻohana i kekahi ʻano ʻē aʻe, ʻo ia hoʻi, ke ʻano ʻāpana hui. No ka ʻāpana hui, ua kaupalena wale ʻia i ka ʻāpana hui i hoʻopaʻa ʻia e like me ka hoʻomohala ʻana o ke ʻano o kēia manawa. Hiki ke hoʻokaʻawale ʻia nā ʻāpana hui i ʻelua mau ʻāpana, ʻo kekahi ka ʻāpana i hana ʻia me ke kila ʻāpana, a ʻo kekahi ka ʻāpana hui i hana ʻia me ke kila ʻāpana a me ka papa kila a i ʻole i hana piha ʻia me ka papa kila. I loko o ke ʻano hoʻopaʻa ʻana, he nui ka maʻalahi o ka ʻāpana hui i hana piha ʻia me nā papa kila. No nā mea hoʻolālā, he mea maʻalahi loa ke koho ʻana i kēia ʻāpana hui, inā paha he ana waho a i ʻole ke ʻano ʻāpana o ka ʻāpana. ʻO ka hoʻohana nui ʻana i ka ʻenehana hoʻopaʻa ʻakomi i nā makahiki i hala iho nei ua hana pū i nā kūlana maikaʻi no ka nui o nā ʻāpana e hoʻohana ana i ke ʻano o ka ʻāpana hoʻonohonoho hoʻopaʻa.
ʻO mākou ka mea hana nui loa o ka ʻāpana hakahaka ma Kina. Hana nui mākou i nā mea i hana ʻia:ʻāpana hakahaka yuantai no ke crane, yuantai ERW paipu, paipu yuantai LSAW, ʻO ka paipu SSAW yuantai, yuantai HFW paipu, ʻO ka paipu humuhumu ʻole ʻo Yuantai.
