Significance of Earthquake Incidence on Response of Plan-Irregular Infilled R/C Buildings

“…The case study structure is a two-ways plan-asymmetric building with eccentric infills in the left and bottom frames, used also in [7]. Previous studies have pointed out the influence of the infills-induced shear failure of the columns, resulting in increased strength and stiffness at low hazard levels, and triggering shear-dominated story mechanisms [15], [16], while the response of the bare frames is characterized by increased flexibility due to bond slip effects [17], [18].…”

“…The elastic modal torsional trends computed from Graphic Dynamics, [1] - [7], are used as a basis to highlight the inelastic contribution to the overall response and the relevant polarization with the earthquake angle. In performance-based earthquake engineering, the identification of synthetic structural and modal parameters in the linear range is critical for the choice of optimal spectrum-based intensity measures, [8].…”
