In earthquake-resistant design, spectral matching techniques have traditionally been used to consider the amplitude and frequency characteristics of ground motions. However, it is crucial to highlight that the effects of duration have not received enough attention in designing buildings on liquefiable soils. Recent research has shown that the duration of ground motions markedly impacts structural responses, playing a crucial role in assessing potential damage to buildings. Therefore, this study explores the effects of ground motion duration on the seismic response of shallow-founded buildings on liquefiable granular soils. Nonlinear dynamic analyses based on the effective stress approach are conducted to capture dynamic the responses of buildings. Furthermore, an advanced constitutive model is employed to effectively capture the stress-strain relationship of both liquefiable and non-liquefiable granular soils under cyclic loading. Numerical results clearly demonstrate that shallow-founded buildings experience greater settlement and tilting when subjected to longer-duration ground motions. Overall, the authors' findings indicate that the duration of strong ground motions is of utmost importance and exerts a substantial influence on the seismic response of structures located in liquefiable soils.
