WebFeb 1, 2024 · In this paper, the near-field earthquakes with pulse-like components were selected, and the dynamic response condition and seismic response law of adding story structure using the base isolation and story isolation technique by elastoplastic time-history analysis method were studied, and study result the far-field ground motion. WebFeb 1, 2024 · The dynamic response characteristics of the three structures under near-fault pulse-like ground motions are analysed and compared with the far-fault ground motions. The results showed that using the base isolation can significantly extend the period of the main structure and reduce the seismic response on the upper structure.

A modal analysis calculates the frequency modes or natural frequencies of a given system, but not necessarily its full-time history response to a given input. The natural frequency of a system is dependent only on the stiffness of the structure and the mass which participates with the structure (including self-weight). It is not dependent on the load function. It is useful to know the modal frequencies of a structure as it allows you to ensure that the frequ… WebSep 28, 2024 · Design/methodology/approach.
