Ke kūʻai nei ʻoe i hale hale hana kila mai kahi mea kūʻai aku Kina. Hauʻoli ʻoe i nā kiʻi a me ka ʻōlelo. A laila, ma mua o kou kau inoa ʻana, ʻōlelo ka mana loiloi kiʻi kūloko i hoʻokahi mea: ʻaʻole e ʻae ʻia nā kiʻi.
ʻAʻole kēia he hāʻule maikaʻi - he hemahema code. ʻO nā code design ka ʻōlelo kūloko o ka ʻenekinia. E hoʻolālā i ka hale hoʻokahi i nā code like ʻole a loaʻa iā ʻoe nā tonnage kila like ʻole, ka nui o nā lālā, ke kaha kiʻi hohonu a me ke kumu kūʻai. E koho i ke code hewa, a hoʻomaka hou ka hana hou mai ka pae hoʻolālā.
Hōʻike kēia ʻatikala i nā mea ʻehā: kahi e pili ai kēlā me kēia ʻōnaehana code nui ʻehā, pehea ka palapala ʻana o nā māka waiwai i kekahi i kekahi, kahi mea i nalo pinepine ʻia e nā papahana anuanu, a me ka mea e kākau ai i kāu RFQ.
Nā Pūnaehana Code Nui ʻEhā: E ʻike i kahi e pili ai kēlā me kēia me ka nānā
Nā Code Design ma ka ʻāpana
| ʻĀpana / ʻano papahana | ʻōnaehana code design | Hoʻouka code | Nā māka kila maʻamau |
| US / ʻAmelika | AISC 360 | ASCE 7 | A36 / A572 Gr.50 / A992 |

ʻElua memo:
- Ua pani ʻia ʻo BS 5950 e nā Eurocodes a ʻike wale ʻia ma kekahi mau kikoʻī o ka papahana hoʻoilina. Hoʻopili maoli nā papahana UK hou i ka Eurocodes me ka UK National Annex.
- Hoʻohana ʻo Australia/New Zealand i ka AS 4100, kahi e hālāwai ai kekahi mau papahana mokupuni o ka Pākīpika. ʻO ka hapa nui o nā papahana honua e koho ma waena o nā Eurocodes a me nā kūlana US.
No ke aha i loaʻa ai nā kumu kūʻai like ʻole i ka hale hoʻokahi
ʻOkoʻa kēlā me kēia ʻōnaehana i ka hui pū ʻana, nā mea palekana a me nā pihi buckling. Hoʻohana ka AISC i nā kumu kū'ē LRFD; hoʻohana nā Eurocodes i nā mea palekana hapa γM. Me ke kila kila 355 MPa like, hiki mai nā koʻikoʻi i ʻae ʻia ma nā ʻaoʻao ʻelua, akā ʻokoʻa nā ʻāpana lālā a me nā tonage kila. Ma nā ʻāpana makani kiʻekiʻe, ʻokoʻa ka ASCE 7 a me EN 1991 i nā coefficient puʻe makani, a ʻike ʻia ka ʻokoʻa tonnage i ke kumukūʻai.
No laila, ʻelua mau mea hoʻolako e hana ana i nā code like ʻole e ʻōlelo nei i ʻelua mau hale like ʻole. Pono nā ʻōlelo hoʻohālikelike like i nā code kūlike.
Palapala Papa Mea Pono: ʻAʻole manaʻo like ka manaʻo
Nā Kaulike maʻamau

FAQ
Q1: Hiki ke hui pū ʻia nā code hoʻolālā hale kila?
A: ʻAʻole ʻōlelo ʻia. ʻO nā hui hoʻouka ʻana, nā wehewehe waiwai, nā ʻano hoʻolālā pili a me nā palena deflection e hele mai nā mea a pau mai ka ʻōnaehana hoʻokahi. Hiki i ka hui ʻana i nā code ke hoʻopōʻino a paʻa paha i ka ʻae ʻana. Inā pono maoli ke kuhikuhi ʻana no kahi papahana kikoʻī, pono e hōʻoia hou ʻia nā mokuʻāina palena āpau me nā waiwai waiwai maoli.
Q2: Hiki iā Q355B ke hoʻololi pololei iā S355JR?
A: I nā piʻi maʻamau, hoʻohālikelike ka ikaika a me nā māka hopena (20 ° C), no laila e ʻae ʻia ka hoʻololi. Akā no nā papahana anuanu (-20 ° C class), pono ʻoe i ka Q355D/S355J2, a pono e hōʻoia hou ʻia nā kaʻina hana like kalapona a me nā kaʻina hana kuʻi i ke code papahana. Pono e hoʻopaʻa ʻia ka hoʻoholo hoʻololi ma ke kākau ʻana e ka hui hoʻolālā.
Q3: Ua like ka palapala hōʻoia EN 1090 me ka hoʻolālā Eurocode?
A: ʻAʻole. EN 1090 e hoʻomalu i ka hoʻokō ʻana i ka hana a me ka mana hana o ka hale hana (kahi koi no ka hōʻailona CE); ʻO ke code hoʻolālā ʻo EN 1993 Eurocode 3. He kūʻokoʻa lākou, a koi pinepine nā papahana Eurocode i ʻelua.
Q4: He aha ka mālama kūikawā e pono ai ke koho i ke kila no nā papahana latitude kiʻekiʻe?
A: ʻElua mau helu: koho i nā māka hopena D/J2 e pili ana i ka wela haʻahaʻa kūloko; a hoʻokau i nā māka maikaʻi weld ʻoi aku ka maikaʻi a me ka mana like kalapona e pale aku i ka haʻihaʻi haʻahaʻa haʻahaʻa. Hoʻopaʻa mākou i nā koi hoʻokolohua hopena i loko o ka ʻaelike kūʻai e pili ana i nā kūlana wela o ka papahana.
