The purpose of this research was to investigate the impact that near-field ground motion has on buildings of varying heights, including low-rise, mid-rise, and high-rise structures. Modelling a building with four stories, eight stories, and twelve stories was accomplished with the help of the SAP2000v22 software. The responses: base shear, drift ratio and storey displacement were found to be proportional to peak ground acceleration (PGA) in low-rise buildings, but proportional to frequency content of the ground motion in mid and high-rise buildings, according to the findings of a dynamic analysis that was performed on all of the models. Because of the normalized base shear, it was made abundantly clear that the influence of high PGA and peak ground velocity (PGV) decreases as the number of storeys in the building increases, while the influence of frequency content increases.

摘要

The purpose of this research was to investigate the impact that near-field ground motion has on buildings of varying heights, including low-rise, mid-rise, and high-rise structures. Modelling a building with four stories, eight stories, and twelve stories was accomplished with the help of the SAP2000v22 software. The responses: base shear, drift ratio and storey displacement were found to be proportional to peak ground acceleration (PGA) in low-rise buildings, but proportional to frequency content of the ground motion in mid and high-rise buildings, according to the findings of a dynamic analysis that was performed on all of the models. Because of the normalized base shear, it was made abundantly clear that the influence of high PGA and peak ground velocity (PGV) decreases as the number of storeys in the building increases, while the influence of frequency content increases.
