Ko ngā hanganga whariki te tihi o te whai huatanga o te hanganga i roto i te hangarau hou. Mā te whakarite i ngā wae tapatoru, ka tohatohahia e ngā hanganga whariki ngā kawenga puta noa i ngā mema e hono tahi ana, kia mau ai te pumau me te iti o te whakamahinga rauemi.
I ēnei rā, ka tautokohia e ngā taura anga ngā mea katoa mai i ngā tuanui papa tākaro nunui ki ngā hanganga piriti nui. Ko te māmā o te āhuahanga e huna ana i tētahi ariā mīhini matatau e whakanui ana i ngā ōwehenga kaha-ki-taumaha. I te mea ka uaua haere ngā taiao tāone, ka piki ake te whakawhirinaki ki ngā pūnaha taura anga mahi-teitei.
Ngā Tikanga Pūmau o te Hanganga o ngā Pourewa: Te Āhua me te Tohatoha Utaina
Ko te kaupapa matua o te angaanga kei roto i te tapatoru. Kāore e rite ki te porowhita taha-whā, kāore e taea e te tapatoru te huri i te āhua me te kore e huri i te roa o ōna taha. Mā tēnei pakari āhuahanga ka taea e ngā angaanga te ātete i te whakarerekētanga. I roto i te angaanga noa, ka pāngia ngā mema e te taumahatanga, te pēhanga rānei.
Hei tauira, i roto i tētahi anga Pratt māmā, ka whakahaerehia e ngā mema poutū te pēhanga, ko ngā mema hauroki ia ka whakahaerehia te taumahatanga. Ka whakamahia e ngā miihini te Tikanga Hononga hei tatau i ngā kaha ā-roto i ia whakawhititanga.
I roto i ngā āhuatanga hoahoa pai, he pai te hoahoapou maitaika taea te tautoko i ngā taumaha maha atu i tōna ake taumaha. Ko te hua o tēnei whai huatanga he whakaiti i ngā nekehanga piko o ngā taura, ā, ka taea e ngā mema te kawe i ngā kaha tuaka. Engari ka arotahi rātou ki ngā kaha tuaka. Mā tēnei arotahi ka taea te hanga i ngā wāhanga angiangi me te whakaiti i ngā utu.
Ko te nuinga o ngā taura ā-ahumahi e whakamahi ana i te maitai kaha-teitei me te modulus o te ngāwari tata ki te 200 GPa. Mā tēnei pakari teitei ka mau tonu te āhua o te hanganga i raro i ngā kawenga taiao taumaha. He maha ngā wā ka whakamahia e ngā kaihoahoa te whakatauira rorohiko hei whakatauira i ngā pūwāhi ahotea i mua i te tīmatanga o te hanga. Mā tēnei tino tika ka whakaitihia te para rauemi e tata ana ki te 15% ki te whakataurite ki te hanganga kurupae tuku iho. Mā te arotahi ki te kawenga tuaka, ka tutuki i ngā kaihangarau ngā whānuitanga e kore e taea e ngā kurupae totoka.
Te Hiranga o ngā Rauemi o ngā Hanganga Whakarewa: Rino me te Konumohe
Ko te whiriwhiri rauemi te mea e whakatau ana i te mahi me te roa o te ora o te anga. Ko te rino tonu te mea nui mō ngā mahi taumaha. Ko te rino karaehe S355, e whakamahia whānuitia ana i roto i ngā kaupapa o te ao, e tuku ana i te kaha tuku o te 355 MPa. Nā tōna pakari ka pai mō ngā piriti me ngā whakakaha whare teitei. I tetahi atu taha, kei te piki haere te rongonui o ngā anga konumohe i roto i te hanga huihuinga me ngā hanganga rangitahi.
Ko te kaha whakaputa o te konumohe 6082-T6 he tata ki te 250 MPa engari he 66% te iti iho i te maitai. E whakaatu ana ngā tatauranga ka taea e te whakamahi i te konumohe te whakaiti i ngā utu kawe mā te 40% mō ngā whakatūnga atamira tūruhi. Ahakoa he pai ake te ātete ahi me te roa o te mau o te maitai, he ngāwari te kawe i te konumohe.
He rerekē anō hoki te ātete ki te waikura i waenga i ēnei konganuku. Ka ātete te maitai piauau ki te waikura mō ngā tekau tau, ahakoa i roto i ngā taiao takutai. Heoi, ka hangaia e te konumohe he paparanga waikura tiaki. Ka ārai tēnei paparanga i te pirau hanganga hohonu me te kore he paninga tāpiri. He maha ngā wā ka pania e ngā kaihanga hou te paninga paura hei whakarei ake i te ataahua me te tiaki.
I te mākete o nāianei, e 70% o te rāngai ahumahi te rahi o ngā taura rino. Ko te konumohe te mea nui rawa atu i roto i ngā mahi whakangahau me ngā whakaaturanga nā te ngāwari o te huihui. Ko te whiriwhiri i ngā rauemi tika ko te whakataurite i te utu tīmatanga, te taumaha e hiahiatia ana, me te roa o te oranga o te kaupapa.
Ngā Rerekētanga Hanganga: Mai i Warren ki ngā Anga Mokowā
Ka tīpakohia e ngā kaihangarau ngā momo angaanga i runga i ngā whakaritenga whānui me ngā whāinga ataahua. Ko te angaanga Warren, e tohuhia ana e ngā tapatoru ōrite, ka whakaiti i te roa katoa o ngā mema. He tino pai te mahi mō ngā whānui i waenga i te 20 me te 100 mita. Mō ngā wāhi nui ake, pērā i ngā taunga rererangi, ka whakamahia e ngā kaihoahoa ngā anga wāhi. Ka tohatohahia e ēnei angaanga 3D ngā kawenga i roto i ngā āhuatanga e toru, kaua i te papa kotahi anake.
E whakaatu ana ngā rangahau ka eke te whānuitanga o ngā anga wāhi ki te neke atu i te 150 mita i roto i ngā kaupapa nui motuhake. Mā tēnei āheinga ka hangaia he roto whānui, tuwhera mō ngā whare hanga me ngā pokapū huihuinga. I roto i te hangarau piriti, ka whakamahia e te anga Howe ngā mema poutū i roto i te kōpeketanga, e tika ana mō ngā hoahoa rakau-taumaha. Nā ngā pūmanawa hou inaianei ka taea te hoahoa whakaputa uri. Ka hangaia e tēnei tukanga he tauira anga kua arotauhia e whakamahi ana i te 20% iti iho i ngā rauemi i ngā tahora tuku iho. Mā ēnei taputapu matihiko ka whakarite kia whai wāhi ia karamu o te maitai ki te hanganga pai.
Hei tāpiri atu, ko ngā taura motuhake pēnei i te taura Fink e whakarato ana i te tautoko tino pai mō ngā tuanui whare noho. Ka aro ia momo ki tētahi wero miihini motuhake. Ka whakaitihia e te taura Warren ngā pūwāhi whakarewa, ka whakaitihia ngā utu mahi hangahanga mā te 10%. I taua wā, ka āwhina te taura K ki te aukati i te piko i roto i ngā hoahoa piriti tino teitei. Mā te kanorau o ngā momo taura ka whakarite he otinga mō ia tirohanga hoahoanga.
Pānga Ōhanga me te Rautaki Tāutanga o ngā Hanganga Tūhono
Ko te uara ōhanga o ngā taura he nui atu i ngā penapena rauemi. Nā te mea ka hangaia ngā wāhanga i roto i ngā wheketere, ka tino heke te mahi i runga i te papa. E whakaatu ana ngā rangahau he 30% te tere ake o te tāutanga o ngā tuanui taura i ngā pūnaha kurupae me ngā pou tuku iho. Mā tēnei tere ka whakaitihia ngā utu putea mō ngā kaiwhakawhanake. I te mākete o te ao, ka taea e ngā taura modular te tuku kaipuke whai hua. Ka taea e te ipu paerewa 40-putu te pupuri i ngā wāhanga mō te tuanui whare putunga 500-mita tapawhā mēnā i hangaia mō te kōhanga.
Hei tāpiritanga, he iti tonu ngā utu tiaki mō ngā anga maitai kua whakapūmautia. He maha ngā wā ka neke atu i te 60 tau te roa o te ora o ngā anga maitai me te iti noa o te wawaotanga. Me piki te hiahia o te ao mō ngā anga maitai mā te 5.5% ia tau tae noa ki te tau 2030. E whai ana tēnei tipu i te whānui haere o ngā ahumahi i roto i ngā ōhanga e tipu haere ana. E hiahiatia ana e ēnei rohe he tikanga hanga tere, pono hoki.
Hei tāpiritanga, nā te nui o te uara para o te maitai, he mea pai ngā taura hei whiringa pumau. I te mutunga o te oranga o te whare, ka taea e ngā rangatira te hangarua tata ki te 98% o te anga maitai. E rata ana tēnei āhua porowhita ki ngā kaipupuri moni e aro ana ki ngā whāinga taiao, pāpori, me te whakahaere. Ka whakapai ake hoki te hanga i waho o te papaanga i te mana whakahaere kounga. Mā ngā tautuhinga wheketere ka taea te whakamātautau ultrasonic o ngā whakarewa, kia 99.9% te angitu i te mara. Mā tēnei pono ka whakaitihia ngā whakaroa utu nui me ngā mōrearea haumaru i te wā hangahanga.
