HEA moʻo
He lepa laula-wela o ka HEAH-kuolama ka maʻamau ʻEulopa, me ke ʻano ʻāpana ʻāpana "H", ʻelua mau maka hana like (pūnaewele) a me ʻelua papa flange. Hōʻike ʻia ke ʻano HEA ʻano H-beam e nā flanges haiki a me ke kiʻekiʻe kiʻekiʻe, e kūpono ai i nā manawa me nā manawa kulou nui, e like me nā alahaka, nā hale kiʻekiʻe, etc.1. ʻO ke kikoʻī, hoʻohana mau ʻia nā kila moʻo HEA no nā hale e koi ai i ka ikaika kiʻekiʻe a me ka ʻoʻoleʻa, e like me nā papa hale e hana maikaʻi ana ma lalo o nā haʻahaʻa kūpaʻa a me ka pae.

ʻO ka hoʻohālikelike ʻana, ʻo ka HEB ʻano H-beam he lāʻau wela hoʻi i hoʻopaʻa ʻia ma lalo o ka hae ʻEulopa, akā ʻokoʻa kona ʻano me HEA. ʻOi aku ka liʻiliʻi o ka ʻāpana cross-sectional o ka HEB type H-beam ma mua o ka HEA, akā ʻoi aku ka laulā o kona flange a ʻoi aku ka mānoanoa o ka pūnaewele, kahi e hāʻawi ai i ka HEB type H-beam i ʻoi aku ka maikaʻi o ka hoʻokō compressive a kūpono i nā hiʻohiʻona noi e koi ai i ka ʻoi aku ka ʻoi aku o ka flange2. 'O ia ho'i, ma kekahi mau hihia, 'oiai kaʻāpana keʻaHe liʻiliʻi ka wahi o HEB, hiki iā ia ke hāʻawi i ke kākoʻo ikaika ma muli o kāna flange ākea a me ka pūnaewele mānoanoa.
1. ʻO nā ʻāpana keʻa a me nā hiʻohiʻona geometric
•moʻo HEA (māmā-H-beam)
▪ʻO nā lau liʻiliʻi a lahilahi (flanges) a me nā pūnaewele lahilahi (nā papa kūwaena waena).
▪Māmā māmā no kēlā me kēia ʻāpana ka lōʻihi a me ka ʻāpana ʻāpana liʻiliʻi.
▪Ka manawa haʻahaʻa haʻahaʻa o ka inertia (ke kūlou ʻana) a me ka modulus ʻāpana, kūpono no nā hiʻohiʻona haʻahaʻa haʻahaʻa.
• moʻo HEB (H-beam maʻamau)
▪ʻOi aku ka laulā a me ka mānoanoa a me nā pūnaewele mānoanoa.
▪ʻOi aku ke kaumaha o ka wae a hoʻonui nui ʻia ka ʻāpana ʻāpana.
▪ʻOi aku ka manawa kiʻekiʻe o ka inertia a me ka modulus pauku, ʻoi aku ka ikaika o ka piʻi ʻana a me ke kūpaʻa paʻa, kūpono no nā hale ukana kaumaha.
3. Nā waiwai mechanical a me nā hiʻohiʻona noi
HEA
▪He kūpono no nā haʻahaʻa māmā a me nā haʻahaʻa haʻahaʻa, e like me nā papa mea kanu māmā, nā paepae liʻiliʻi a i ʻole nā hale lawe ʻole.
▪Ka hoʻokele waiwai maikaʻi, mālama i nā kumukūʻai waiwai.
HEB
▪Hoʻohana ʻia i nā hiʻohiʻona haʻahaʻa kaumaha, e like me nā alahaka nui, nā kolamu hale kiʻekiʻe a i ʻole nā mea kākoʻo mīkini kaumaha.
▪Ka ʻoʻoleʻa kiʻekiʻe a me ka ikaika, akā ʻoi aku ka nui o nā kumu kūʻai.
4. Nā moʻo H-beam ʻEulopa ʻē aʻe
▪HEM moʻo: ʻoi aku ka mānoanoa a me nā pūnaewele pūnaewele, i hoʻolālā ʻia no nā haʻahaʻa koʻikoʻi (e like me nā kumu ʻoihana koʻikoʻi).
▪IPN/IPE pūʻulu: E like me HEA/HEB, akā me ka hoʻolālā flange like (ʻaʻohe pali ma ka ʻaoʻao i loko o ka flange).
Nā wahi noi
Ma muli o nā ʻokoʻa o nā hiʻohiʻona i luna, ʻo ka noi ʻana o HEA a me HEB ʻano H-beams i ka ʻenekinia maoli e kālele pū ana i nā ʻano like ʻole. ʻOi aku ka maikaʻi o ka HEA H-beam no nā wahi e koi ai i ka rigidity kiʻekiʻe a me ka ikaika kiʻekiʻe, e like me ka ʻōnaehana kākoʻo kumu o nā hale nui a i ʻole ka paipu kumu o nā hale kiʻekiʻe. ʻO ka HEB H-beam, ma muli o kona ākea ākea nui a me ka pūnaewele mānoanoa, hana maikaʻi loa i ka wā i hoʻokau ʻia i nā haʻahaʻa kaomi nui. No laila, hoʻohana pinepine ʻia i ka hoʻokumu kumu o nā mīkini kaumaha a i ʻole nā mea kanu ʻoihana me nā koi kiʻekiʻe no ka hiki ke hiki.
