## 2 **Introduction**
Nevertheless, in the paper authored by [PERSON], [PERSON], and [PERSON] a method for evaluating the cumulative damage of buckling-restrained braces under multi-hazard events that are expected to occur during the service life of a high-rise building, is introduced [27]. The paper authored by [PERSON] [28] provides a review on the methodologies for seismic site classification according to the Chilean regulations from their implementation in the 1930s to the most recent proposal in 2018-2021. In the last paper authored by [PERSON], [PERSON], [PERSON], [PERSON], and [PERSON] the dynamic characteristics of a multistory RC buildings are estimated, considering two different identification techniques [29]. Data based on earthquake acceleration time histories recorded by accelerometers placed throughout the building are used. This research received no external funding.

My thanks and congratulations to all the authors for submitting their work. My sincere gratefulness to all reviewers for their effort and time spent to help authors improving their papers. Finally, I want to express my gratitude to the editorial team of Applied Sciences for their effective and friendly collaboration. I wish this collection to serve as an inspiration for future research in seismic engineering of structures. The author declares no conflict of interest. References
