A Combination-Type Earthquake Intensity Measure for Super High-Rise Building
Abstract eng: As the superior performance of spectral characteristic of spectral velocity over that of spectral acceleration and spectral displacement in the long period range, a new combination-type ground motion intensity measure considering higher modes based on spectral velocity is developed for super high-rise building structures. The proposed IM multiplies the corresponding spectral velocity of some modes. For a super high-rise building with fundamental period more than 9s, the lower three modes are adequate to get an optimal result. The proposed IM and several other IMs are analyzed from the perspective of efficiency, sufficiency and scaling robustness. The proposed IM is proved to be more superior to other IMs. For a super tall building, the IM which considers higher modes is more practical compared to the one considering period elongation.
