Abstract:	Protipotresno projektiranje armiranobetonskih (AB) konstrukcij kljub določenim omejitvam še vedno temelji večinoma na rezultatih linearne elastične analize. Pri oceni potresnega odziva se AB-stene, povezane zgolj s ploščami, običajno obravnavajo kot konzolne stene, pri čemer se plošče upoštevajo le kot horizontalne diafragme toge v svoji ravnini, njihov upogibni odziv pa se običajno zanemari. Pretekle raziskave so pokazale, da lahko upogibne lastnosti plošče pomembno vplivajo na odziv sten, še zlasti, če so te visoke in vitke. Plošče lahko povežejo stene v okvirom podoben sistem. V tako povezanih stenah lahko potresni vplivi bistveno vplivajo na njihove osne sile, kar lahko spremeni njihovo togost in nosilnost ter povzroči, da se v nelinearnem območju potresne zahteve med njimi močno prerazporedijo. Te učinke je z elastičnimi metodami težko zanesljivo upoštevati. Zato smo predlagali razmeroma preprost postopek projektiranja, ki temelji na nelinearni potisni analizi. Predlagana metoda združuje N2-metodo in principe načrtovanja nosilnosti. Njeno učinkovitost smo ovrednotili na širšem naboru stavb z AB- stenami, z uporabo nelinearne analize časovnega odziva. V primerjavi z običajnimi postopki projektiranja, ki temeljijo na elastični analizi, predlagana metoda omogoča zanesljivejšo oceno potresnih zahtev, učinkovitejše in varnejše protipotresno projektiranje AB-sten ter zmanjšanje njihovih poškodb.

Title:	Potresno odporno projektiranje AB-sten, povezanih s ploščami z uporabo nelinearne potisne analize
Abstract:	Linear elastic analysis remains a cornerstone of seismic design, despite its limitations in capturing the nonlinear behaviour of reinforced concrete (RC) structures. RC walls connected only by slabs are typically modelled as assemblies of cantilever walls, where slabs are considered to act solely as rigid diaphragms. However, recent studies have shown that in configurations such as elevator shafts with closely spaced slender walls, slabs can provide significant coupling between the walls. In such cases, considerable axial forces can be induced in the wall piers, altering their stiffness and strength and causing notable redistributions of seismic demand in the nonlinear range–effects that cannot be accurately captured using elastic methods. To address this issue, a simple and efficient pushover-based design method for RC walls coupled only by slabs, without coupling beams, is proposed. The method integrates the N2 method and the capacity design principle s. Its effectiveness was verified on various RC wall buildings using nonlinear response history analyses. Comparisons with structures designed using traditional force-based methods demonstrate that the proposed approach predicts seismic response more accurately, improves overall performance, and reduces structural damage.
