Utjecaj otvora na hladno oblikovane čelične posmične zidne panele ; Effect of openings on cold formed steel shear wall panels
U radu se numeričkim postupkom istražuje utjecaj otvora na cjelokupno ponašanje hladno oblikovanih čeličnih posmičnih zidnih panela (CFS-SWP) s oblogom od rebrastog lima. Prvo je provedena validacija referentnog numeričkog modela u smislu posmične otpornosti i nelinearnog ponašanja CFS-SWP-a. Definiran je i provjeren način sloma CFS-SWP-a s otvorom. Zatim je provedena parametarska studija o utjecaju veličine i položaja otvora, te je utvrđeno da položaj otvora bitno utječe na učinkovitost CFS-SWP-a. Referentni se model može koristiti u fazi projektiranja za prilično točno ocjenjivanje umanjene krajnje otpornosti pojedinačnih CFS-SWP-a za bilo koju veličinu i položaj otvora. ; In this paper, the effect of openings on global performance of Cold Formed Steel Shear Wall Panels is investigated numerically using the ABAQUS software. A benchmark model is first validated in terms of lateral shear capacity and nonlinear behaviour of the CFS-SWP. The failure mode of the CFS-SWP with opening is identified and validated. Subsequently, a parametric study on the effect of size and position of openings is conducted, in which the opening position is found to have a significant impact on the CFS-SWP performance. The benchmark model can be used for design purposes to evaluate with good accuracy the reduced ultimate strength of individual CFS-SWPs for any size and position of openings.
