Hoʻolauna pōkole o I-beam:
ʻO I-beam, ʻike ʻia hoʻi ʻo Steel Beam (inoa Pelekane ʻo I Beam), he ʻāpana kila me kahi ʻāpana I-like.Hoʻokaʻawale ʻia ʻo I-beam i ka maʻamau a me ka māmā I-beam, H - ke kila kila ʻekolu.Hoʻohana nui ʻia ʻo I-beam i nā ʻano hale like ʻole, atlas Bridges, nā kaʻa, nā kākoʻo, nā mīkini a pēlā aku.ʻO ka I-beam maʻamau a me ka māmā I-beam aʻa ʻēheu liʻiliʻi liʻiliʻi i ka lihi, aia kekahi Angle, I-beam maʻamau a me ke ʻano I-beam māmā e hōʻike ʻia e ka helu o nā kenimika o ka pūhaka kiʻekiʻe He helu Arabic, pūnaewele, flange. ka mānoanoa a me ka laula flange o nā kikoʻī like ʻole i ke kiʻekiʻe o ka pūhaka (h) × ka laulā wāwae (b) × ka mānoanoa pūhaka (d).Hiki ke hōʻike ʻia ka kikoʻī o ka I-beam maʻamau e ke kumu hoʻohālike, hōʻike ke kumu hoʻohālike i ka helu o nā kenimika o ke kiʻekiʻe o ka pūhaka, e like me ka 16 # maʻamau.Inā he nui nā laula wāwae ʻokoʻa a me ka mānoanoa pūhaka no nā kaola I me ke kiʻekiʻe pūhaka like, pono e hoʻohui ʻia ʻo A, B, a me C i ka ʻaoʻao ʻākau o ke kumu hoʻohālike e ʻike ai iā lākou.
Hoʻohana i ka I-beam:
I-beam maʻamau, I-beam māmā, no ka mea, he kiʻekiʻe ka nui o ka ʻāpana, haiki, no laila ʻoi aku ka nui o ka manawa o ka inertia o nā lima lima ʻelua o ka ʻāpana, no laila, hiki ke hoʻohana pololei ʻia i ka piko o ka mokulele pūnaewele. nā lālā a i ʻole ke ʻano o ka hoʻolālā lattice o nā lālā ikaika.ʻAʻole kūpono ka hoʻohana ʻana i nā lālā compression axial a i ʻole nā ​​lālā kulou e kū pono ana i ka mokulele pūnaewele, kahi i kaupalena ʻia ai i ke ʻano o ka noi.
