Space Truss Structure: Iyo Inofarirwa Sarudzo yeMakuru-span Public Zvivakwa

Sebazi rakakosha renzvimbo yegridhi chimiro, space truss chimiro chinoratidza hukuru hwemakina mashandiro, huremu huremu, huremu hwakanyanya, kugona kweseismic kuramba, mutengo wakaderera uye nyore kuumbwa. Yakave iyo inosarudzika hurongwa hwekugadzira matenga ezvivakwa zvakakura zveveruzhinji senge airport terminal, nhandare, nzvimbo dzekuratidzira uye zviteshi.

Space truss chimiro imhando huru ye spatial grid system. Iyo spatial bar chimiro chinoumbwa nenhengo dzakarongwa nguva dzose uye dzakabatanidzwa kuburikidza nemajoini. Iyo inonyanya kugadzirwa seyakapetwa kaviri-layer kana akawanda-layer flat grids, akasiyana kubva kune imwechete-layer latticed shells.

Space truss zvimiro zvinowanzo gamuchirwa kune zvivakwa zvedenga, zvakanyanya mune imwechete-layer uye flat shapes. Zvinoshandiswa zvakanyanya muzvivakwa zveveruzhinji kusanganisiragymnasiums, horo dzekuratidzira, zvivako zvekumirira chiteshiuyeairport terminals. Mumakore achangopfuura, ivo vakashandiswawo kune zvivakwa zveindasitiri sengematura, hangars uye mafekitari workshops. Nekurumbidza mabhenefiti akasiyana-siyana, anomira pachena senzira huru yezvivakwa zveveruzhinji.

Yakakura-span column-isina nzvimbo.

Space truss zvimiro zviri nyore kuwana makoramu-yemahara yekuvhara kubva pa60 kusvika 150 metres, ichigadzira yakavhurika yakazara uye yakapamhama mukati. Beijing Capital Gymnasium inotora nzvimbo truss chimiro chine hurefu hwemamita makumi mapfumbamwe nemapfumbamwe ne112.2 metres. Iyi mukana inoita kuti space truss ive sarudzo huru kune airport terminal matenga.

Kubudirira kwehupfumi kunoshamisa.

Chimiro chacho chinoratidza kushandiswa kwesimbi yakaderera uye inodzoreka mari yose. Iyo simbi yakadururwa yeHangzhou Renhe Grain Reserve Terminal inoshandisa kaviri-layer square piramidi space truss, ine hurefu hurefu hwemamita makumi mapfumbamwe neshanu, ichiunza inodhura-inoshanda kuvaka.

Yakanakisa seismic kuita.

Kutenda kune yakakwira spatial stress redundancy, yakanaka ductility uye light self-weight, space truss zvimiro zvinopfuura zvechinyakare kongiri zvimiro mukuramba kudengenyeka. Sechivakwa chepamusoro-chepamusoro-soro munzvimbo yekudengenyeka kwenyika, Beijing Daxing International Airport Terminal ine 1152 yekuzviparadzanisa mabearings uye 160 dampers kuti ive nechokwadi chekudzivirirwa kunoshanda kubva pakudengenyeka kwenyika kwakasimba.

Flexible architectural styling.

Chimiro chacho chinogona kuona zvimiro zvakaoma senge hyperboloid, yemahara-fomu yepamusoro uye inoenderera mberi wave pamusoro, ichisangana neyakaomesesa dhizaini yezvivakwa zveveruzhinji zvemazuva ano. Denga guru reZhuhai Airport T2 Terminal rinotora refu-span variable-curvature hyperboloid hollowed steel truss. Shenzhen Bay Sports Center inosanganisa single-layer latticed shell uye kaviri-layer curved truss, ese ari maviri anoshanda semuenzaniso wezvivakwa zvekuvaka.

Uye zvakare, space truss zvimiro zvinouya nenzira dzakasiyana siyana nemhando huru seinotevera:

Iyo kaviri-layer space truss, inoumbwa nepamusoro chords, pasi chords uye webhu nhengo, ndiyo inonyanya kugamuchirwa fomu.

Kusarudzwa kwenzvimbo truss chimiro kunotemerwa zvakakwana nezvinhu zvinosanganisira kuvaka planar chimiro, zvivakwa zvekuvaka, mutoro, span, kutsigira mamiriro uye mutengo wekuvaka.

Pakazere, kutora nzvimbo truss zvimiro zvinogonesa kugadzira nzvimbo dzakakura nezvinhu zvishoma. Kupesana nemashure ekusimudzirwa kwemhando yepamusoro uye kuvaka kwakasvibira, space truss inoshanda seyakasimba sisitimu musana wezvivakwa zvakakura zveveruzhinji.
