1. Lingaliro la Axial Force
Pomanga, mphamvu ya axial imatanthawuza mphamvu yosunthika kapena yopondereza yomwe imagwiritsidwa ntchito pachigawo chotsatira mbali yake ndi mphamvu zamkati. Itha kutchedwanso kupsinjika kapena kupsinjika. Muzitsulo zachitsulo, mphamvu ya axial imatanthawuza kuchuluka kwa mphamvu zopondereza ndi zowonongeka zomwe zimagwiritsidwa ntchito pachigawocho ndi mphamvu zometa ubweya. Ndichinthu chofunikira kwambiri chomwe chimakhudza mphamvu yobereka komanso kukhazikika kwazitsulo zachitsulo.
2. Makhalidwe Okhazikika a Axial Forces muzitsulo zazitsulo
Pakukonza ndi kupanga zitsulo zazitsulo, mphamvu za axial ziyenera kuyendetsedwa kuti zitsimikizire kuti chitetezo champhamvu ndi chomveka. Mtengo wokhazikika wa mphamvu ya axial muzitsulo zachitsulo umatanthawuza kuchuluka kwa katundu ndi katundu wogwiritsidwa ntchito pansi pa zikhalidwe zolemetsa zomwe zimagwiritsidwa ntchito pogwiritsa ntchito chitetezo china pazochitika zosiyanasiyana. Ndilo chizindikiro chofunikira poyezera momwe chitetezo chimagwirira ntchito pazitsulo zachitsulo.
3. Lingaliro la Preloaded Axial Force
Mukagwiritsidwa ntchito, zitsulo zachitsulo zimatha kukhala ndi axial deformation ndi kusintha kwachisokonezo chifukwa cha zinthu zosiyanasiyana, monga kusinthasintha kwa kutentha ndi kusiyana kwa katundu. Pofuna kuonetsetsa kuti ntchitoyo ikhale yokhazikika pakatha ntchito yomanga, kuchuluka kwa axial tension, komwe kumatchedwa preloaded axial force, kumagwiritsidwa ntchito pazitsulo zazitsulo panthawi yomanga.
Mphamvu ya axial yodzaza kale imasinthidwa kutengera momwe zinthu ziliri panthawi yomanga. Ukulu wake umatsimikiziridwa ndi zochitika zenizeni ndi zofunikira za polojekiti, ndipo ziyenera kusungidwa mkati mwamtundu wina kuti zitsimikizire kuti sizikhudza ntchito yotetezedwa yotsatila yothandizira zitsulo.
IV. Kusiyana Pakati pa Standard Axial Force ndi Preloaded Axial Force
Ngakhale mphamvu ya axial yokhazikika komanso mphamvu yodzaza ndi axial imatanthawuza mphamvu ya axial yothandizira zitsulo, ntchito zawo ndi matanthauzo ake zimasiyana. Mphamvu yokhazikika ya axial ya chitsulo chothandizira ndi mtengo wokhazikika, chizindikiro chofunikira chofotokozera panthawi yokonza ndi kumanga. Mtengo wake umatsimikizira chitetezo ndi mphamvu zonyamula katundu wothandizira zitsulo. Komano, mphamvu ya axial yodzaza kale ndi mphamvu ya axial yomwe imawonjezeredwa pakumanga kutengera momwe zinthu ziliri. Zimapangidwa kuti zisinthe kupanikizika kwa chithandizo chachitsulo ndikuonetsetsa kuti kukhazikika kwake kwa nthawi yaitali.
Mwachidule, mphamvu ya axial yokhazikika komanso mphamvu ya axial yodzaza kale imatanthawuza mphamvu ya axial ya zothandizira zitsulo, koma zimakhala ndi ntchito ndi matanthauzo osiyanasiyana. Panthawi yokonza, kumanga, ndi kugwiritsa ntchito zothandizira zitsulo, mphamvu ya axial yazitsulo zothandizira ziyenera kuyendetsedwa bwino ndi kusinthidwa kuti zitsimikizire chitetezo chawo ndi kukhazikika.
