Earticle

This paper conducted a numerical analysis of the 2016 Gyeongju and 2017 Pohang earthquakes in order to analyze the damage potential of eccentric short-period structures. First, an analysis of the earthquake records of the Pohang and Gyeongju earthquakes was conducted. Followed by deriving the equation of motion including torsion, the damage potential was analyzed through the response to each earthquake record. In this study, an exact solution related to the natural frequency of the short-period asymmetrical building was derived, and based on this, it was confirmed that the total response depends not only on the variable related to eccentricity, but also on the natural frequency ratio of the excitation direction and the non-excitation direction. Based on these results, the separation of the natural frequency from the parameters related to the eccentricity and the ratio of the frequency of the direction not excitation to the direction of excitation was confirmed through time history analysis.
