Qof Barqooyinka Construction Rebar ee Durable Infrastructure Projects

Qarqaradka dhexeeynta waxaa lagu soo diray magacaan ku saabsan ee ka mid ah qofka ugu yaranka iyo xaaladda la'anta, kamaanteed, macaalada degmada, qoraxda iyo fasikilada nukliyaar. Waxaa laga heli kartaa qarqaradaha oo lacagga leh ≥500 MPa, kuwaas oo ahaantahay microalloying (vanadium, niobium, titanium) ama tratamentada thermomechanical, ku jira inaad ugu yeel kartaa mikrostruktureeda dhexeeya oo ka soo jeedi kartaa lacag (500–600 MPa) iyo amal (Agt ≥7.5% sidoo kale kuma ogolaanso seismic compliance). Qeybta ka mid ah ayaa ku jirin HRB 500 (China), ASTM A1035 (USA, 550 MPa yield), iyo BS 8666 Grade 600B (Europe, 600 MPa), ku yaal amalada rib configurations (kan ku jiran ribs ee three dimensional ribs ee GB/T 1499.2) si aad ugu yeel kartaa lacagga bond strength by 25% carruurta conventional rebars. Fadhiyadaha ka mid ah ayaa ku jirin material usage ka badan (20–30% lacagga adeegsiga Grade 400 rebars) iyo fire resistance adeegsiya, kaalinsan lacag 80% marka deegaan 300°C sidii 2 saac. Xaqqaadka lacagga ka mid ah ayaa ku jirin testing dheer: ultrasonic testing magacaan internal defects, fatigue testing (2 million cycles at 60% yield strength), iyo corrosion potential testing (ASTM G59) carruurta coated products. Dhibaatooyinka ayaa ka mid ah megaprojects kamaanteed, skyscrapers (core wall reinforcements), long span bridges (deck slabs), iyo industrial plants (equipment foundations), carruurta rigorous standards ee ku jirin AISC 341 (seismic steel structures) iyo EN 1992 1 1 (Eurocode 2). Waxaa manufacturers macluumaadka finite element analysis support ka soo baxay si aad ugu yeel kartaa rebar layouts, kaalinsan construction costs marka aad safety margins ka soo galitaan extreme load cases.
