Nonlinear time-history analyses assess how height and soil type affect structural behaviour during seismic events.
Earthquake intensity measures, which quantify ground motion characteristics, serve as input parameters for predicting structural behaviour and response to seismic events. The large number of these measures, differential applicability across different types of structures and impending adoption of new intensity measures in future Eurocode standards require further research. This paper presents the results of nonlinear time-history analyses performed on individual in-plane RC shear walls. The walls vary in height: six, ten and fourteen stories, and are founded on two distinct soil types, A and C. For the analysis, 102 ground motion records were used. Current earthquake intensity measures are evaluated, and statistical processing of the data reveals correlations between specific intensity measures and structural response parameters. The study concludes with insights into the efficacy of the examined intensity measures in the context of shear walls.
