Quantifying the higher-mode effects on the seismic demands of buildings is beneficial not only for increasing awareness of the characteristics of seismic responses of buildings but also in the development of rapid/simplified seismic assessment methods. This study proposes an approach that is applicable to quantifying the aforementioned effects, covering the full range of building heights and deformation types. The vehicle used for this proposed approach is the generalized building model, which is modified from the conventional cantilever beam model. The higher-mode effects on floor displacements, inter-story drift ratios, floor accelerations, and base shears are investigated. |
