Kutsogola mu Uinjiniya Wopanga: Axial Compression Performance ya CFRP-Reinforced Concrete-Filled Double-Skinned Tubes

Mawu Oyamba

Pankhani ya uinjiniya wamapangidwe, kufunafuna zida ndi mapangidwe omwe amapititsa patsogolo magwiridwe antchito ndi kulimba kwazinthu zomanga kukupitilira. Kafukufuku waposachedwapa waunikira ntchito axial psinjika ntchito konkire wodzazidwa awiri khungu machubu (CFDST) analimbitsa ndi mpweya CHIKWANGWANI analimbitsa polima (CFRP). Njira yatsopanoyi ndiyofunikira makamaka kwamakampani ngati Tianjin Reliance Steel, omwe amagwira ntchito yopanga machubu achitsulo apakati ndi amakona anayi, kuphatikiza SHS (Square Hollow Sections) ndi RHS (Rectangular Hollow Sections). Nkhaniyi ikuyang'ana zomwe zapezedwa mu kafukufukuyu, zomwe zachitika pamakampani omanga, komanso momwe Tianjin Reliance Steel ilili kuti ikwaniritse zomwe zikufunika kusintha pamapangidwe.

Kumvetsetsa Machubu Akhungu Awiri A Konkrete (CFDST)

Machubu opangidwa ndi konkriti okhala ndi zikopa ziwiri ndi chinthu chophatikizika chomwe chimaphatikiza phindu lachitsulo ndi konkriti. Chubu chakunja chachitsulo chimapereka kutsekeka kwapakati pa konkriti, kukulitsa mphamvu yake yopondereza komanso ductility. Kapangidwe kameneka kamakhala kothandiza kwambiri m'malo omwe nthawi zambiri amakhala ndi zivomezi, pomwe zomanga zimayenera kupirira mphamvu zakutsogolo. Kafukufukuyu amayang'ana mizati 15 ya CFDST, iliyonse ili ndi njira zolimbikitsira za CFRP, kuti awone momwe amagwirira ntchito.

Udindo wa CFRP Pakulimbitsa Zomangamanga

Carbon fiber reinforced polymer (CFRP) ndi chinthu chopepuka, champhamvu kwambiri chomwe chadziwika bwino pamapangidwe ake chifukwa cha makina ake abwino kwambiri komanso kukana kuwonongeka kwa chilengedwe. Mwa kuphatikiza CFRP mu kapangidwe ka mizati ya CFDST, mainjiniya amatha kusintha kwambiri mphamvu yonyamula katundu ndi magwiridwe antchito onse azinthu izi. Kafukufukuyu akufufuza njira zingapo zolimbikitsira, ndikuwunika momwe masinthidwe osiyanasiyana a CFRP angathandizire kukhathamiritsa kwa axial pamizatiyo.

Mfundo Zazikulu za Phunziroli

Kafukufukuyu akuwunikira zomwe zapezedwa zingapo zofunika zokhudzana ndi kagwiridwe ka axial compression of CFRP-reinforced CFDST columns:

1. Mphamvu Yowonjezera Yonyamula Katundu: Kuphatikizidwa kwa kulimbikitsa kwa CFRP kumawonjezera kwambiri mphamvu yonyamula katundu wa mizati ya CFDST. Kafukufukuyu akuwonetsa kuti njira zolimbikitsira zenizeni zimatha kupititsa patsogolo magwiridwe antchito poyerekeza ndi machubu achikhalidwe odzaza konkriti.
2. Ductility and Energy Absorption: Kulimbitsa kwa CFRP sikumangowonjezera mphamvu komanso kumapangitsanso kusinthasintha kwa mizati. Mkhalidwewu ndi wofunikira kwambiri pamachitidwe a chivomezi, pomwe zida ziyenera kuyamwa ndikutaya mphamvu pakachitika chivomezi.
3. Njira Zolephera: Kafukufukuyu akuwonetsa mitundu yosiyanasiyana yolephereka kwa mizati ya CFRP-yolimbitsa CFDST, ikupereka zidziwitso zamtengo wapatali za momwe zinthuzi zimakhalira pansi pa katundu wa axial. Kumvetsetsa njira zolepherekazi ndikofunikira kuti mupange zomanga zotetezeka komanso zolimba.
4. Njira Zabwino Zolimbikitsira: Poyerekeza masinthidwe osiyanasiyana olimbikitsira a CFRP, kafukufukuyu akuwonetsa njira zabwino zomwe zimakulitsa magwiridwe antchito ndikuchepetsa kugwiritsa ntchito zinthu. Zomwe anapezazi ndizofunika kwambiri pazomangamanga zotsika mtengo.

Zokhudza Makampani Omanga

Zotsatira za phunziroli zimakhala ndi zofunikira kwambiri pa ntchito yomangamanga, makamaka pakupanga ndi kukhazikitsa zinthu zomanga m'nyumba zapamwamba, milatho, ndi zina zofunika kwambiri. Kuchita bwino kwa mizati ya CFDST yolimbitsidwa ndi CFRP kungapangitse nyumba zotetezeka, zolimba zomwe zimakhala zokonzeka kupirira zovuta zobwera chifukwa cha masoka achilengedwe ndi katundu wolemetsa.

Kuphatikiza apo, kutha kukhathamiritsa njira zolimbikitsira zimalola mainjiniya kupanga zomanga zomwe sizongolimba komanso zotsika mtengo. Izi ndizofunikira makamaka panthawi yomwe kukhazikika ndi kutsika mtengo ndizofunikira kwambiri pazomangamanga.

Tianjin Reliance Steel: Mtsogoleri mu Mayankho a Structural

Monga opanga otchuka a machubu achitsulo apakati ndi amakona anayi, kuphatikiza SHS ndi RHS, Tianjin Reliance Steel ali ndi mwayi wopeza bwino kupita patsogolo kwaukadaulo wa CFDST. Kudzipereka kwa kampaniyo pazabwino komanso zatsopano zimagwirizana ndi zomwe zapeza pa kafukufuku waposachedwa, kuwapangitsa kuti azitha kupereka mayankho apamwamba kwa makasitomala awo.

Zogulitsa za Tianjin Reliance Steel zikuphatikiza mitundu yosiyanasiyana yamachubu achitsulo omwe angagwiritsidwe ntchito pomanga mizati ya CFDST. Pogwira ntchito limodzi ndi mainjiniya ndi omanga, kampaniyo imatha kupereka mayankho ogwirizana omwe amaphatikiza kulimbikitsa kwa CFRP, kuwonetsetsa kuti zinthu zawo zikukwaniritsa zofunikira zantchito zamakono zomanga.

Mapeto

Kufufuza kwa ntchito ya axial compression mu machubu akhungu awiri a CFRP-wolimbitsa konkire kumayimira kupita patsogolo kwakukulu muukadaulo wamapangidwe. Zotsatira za kafukufukuyu zikugogomezera kuthekera kwa zida zophatikizikazi kuti zithandizire chitetezo, kulimba, komanso mphamvu zomangira. Pamene makampaniwa akupitabe patsogolo, makampani ngati Tianjin Reliance Steel ali okonzeka kutsogolera njira zothetsera mavuto omwe amakwaniritsa zofunikira zamapulojekiti amakono. Polandira matekinoloje atsopano ndi zipangizo, ntchito yomangamanga ikhoza kumanga tsogolo lokhazikika, lotha kulimbana ndi zovuta za mawa.
