Equivalent single-degree-of-freedom (ESDOF) representation of typical box-shape unreinforced masonry (URM) building under earthquake-induced loading taking into account typical deformation components in the fundamental mode shape [Δ sh : horizontal displacement due to shear deformation, Δ fl : horizonal displacement due to flexural deformation, Δ open : horizontal displacement contribution of masonry wall openings, Δ in.pl : in-plane horizontal masonry wall displacement (consists of Δ sh , Δ fl , Δ open ), Δ out.pl : out-of-plane horizontal masonry wall displacement due to out-of-plane bending, M: ESDOF generalized mass, K: ESDOF generalized stiffness]
